    Machine-Generated Transcript

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    In today’s episode, let’s do a bake-off. I am, of course, an audio nerd, and I enjoy working with various different audio products, testing things out, trying to see what makes my life simpler, easier, or delivers higher quality.

    So today we’re going to be doing a bake-off, and the bake-off we’re going to do is using the iPhone 15 and the Blackmagic video camera. I’ve got a new set of microphones, the newer CM-CM-301. Full disclosure, I paid for these. Trust Insights paid for these. This is unsponsored, un-incentivized.

    If you have gear that you would like to send me to test and evaluate, I’ll be more than happy to do so. However, fair warning, I give honest reviews. So something sucks. If your gear sucks, I’m going to say it sucks. So just fair warning.

    All right. So the first thing we’re going to do is we’re going to get Blackmagic running on the phone here. And you know what would be fun? I wonder if I can do phone. No, I can’t do phone mirroring. So instead, what I’m going to do is I’m just going to turn on the screen recorder on my phone to record what’s going on on screen.

    And the first thing we’re going to do is we’re going to start with the control. I’ve got some fans running in my basement office here because that is how I do laundry. And so our first test is going to be just the bare phone, the bare audio off of the iPhone, the iPhone microphone. Let’s go ahead and go to camera here. And this is a test of the iPhone’s native front facing microphone using the iPhone 15. Okay, so that’s our first test.

    Second test, AirPods, AirPods Pro 2, good headphones. I love these things. Let’s see how well they do for recording audio. I’m going to move these to my iPhone. And let’s not do that. There we go. And let’s go ahead and set up audio source AirPods. This is now using the Blackmagic camera app along with the native microphone on the AirPods. Let’s see how this sounds. Okay. That’s the AirPods.

    Let’s move to my control for today. I’ve been using the Anchor Work M650s. These are decent microphones is the way I would describe them. They are not perfect. They do have some impressive noise cancellation, which I do like. And I especially like the fact that the clips are magnetic, which is super handy. Let’s go ahead and close this up. We’re going to plug this into the phone like so.

    And I’m going to switch audio source. This is a recording of the Anchor Work M650 microphones using the USBC connection on the iPhone. All right. So that’s the Anchor Work, the M650, which is pretty useful. I like the fact that it has the charging case. I like the magnetic clips. What I don’t love about it is sometimes it just loses stuff, which is annoying.

    So today we have the newer CM31. They give you a bag full of wiring, which that part I don’t love as much. Let’s go ahead and get the microphone in the base transmitter turned on here. There we go. So transmitter one is on. Now we need to get this clipped on me. I do miss those magnetic clips. Oh yeah, that’s not great. There it goes.

    And got to get dressed here to go from the transmitter and go straight USBC, which would require me to have a USBC cable. No, no, I’m going to unplug the keyboard at the moment because I don’t need it for this. Okay, so USBC straight into the iPhone. Let’s change USB audio. This is the newer CM31 using the lavalier there and the USBC connection to the base receiver. So let’s see how this sounds on the iPhone 15.

    Plug everything back in here. Now next, we need to actually get the videos off over the phone. So what did we learn? Something really went wrong with the Anchor. Those definitely came way too hot and even set to zero gain. So I think I’ll take that down to like a minus seven gain.

    The newer microphones did not sound terrible. These are like 89 dollar microphones. These are not the high end, you know, 2, 300. Do they sound as good as, you know, a Senheiser or Rode? No. Do I expect them to? Also, no. They were like 89 dollars.

    And they have onboard memory and the fact that I can clip the base station in either by straight USBC or they do have an audio cable to USBC, which I don’t know how useful that would be. So it’s not bad. It’s not bad. Would I use this for like a AAA title video game or a studio recording? No, of course not. Would I use this on stage? Yeah, I mean, that’s good enough, certainly better than using the phone or using your AirPods. It’s good enough.

    Combine that with good post production and you would have a pretty decent recording experience. So if you’re looking for live mics that are rechargeable and not the most convenient carrying case, but get the job done and don’t have a triple digit price tag—they’re not bad. They’re not bad.

    So I’ll put a link to the product on Amazon if you want to go buy it. Again, they did not send me this. I paid for this out of pocket, but I’m probably going to keep it because it’s not bad. And given the issues I had with the Anchor ones, if you’re doing a talk where you absolutely, positively need to have good audio, the fact that the software on the M650s does these really weird, wonky things from time to time is kind of a deal killer for an event where that’s really, really important.

    All of them have mic ins. So if you want to use a lav mic in addition to the transmitter, you can, which is handy. Obviously, if you’re doing that, then you can just clip the transmitter to your belt or behind your dress or whatever, however you choose to wear these things. Not bad, not bad.

    That’s going to do it for this episode. Thanks for tuning in. Talk to you on the next one.

    Mind Readings: Turning a Lavalier Mic Into a Handheld Mic

    In today’s episode, you’ll see a simple hack to transform a lavalier microphone into a handheld microphone. I’ll walk you through how I used a Rode Wireless Go transmitter, a power bank, and a USB-C connector to create a more ergonomic and acoustically sound setup. You’ll learn why this method, while not ideal for a lavalier mic, is preferable to holding it directly in your hand. Discover a cost-effective alternative to expensive handheld adapters and improve your audio quality with this clever hack!

    Machine-Generated Transcript

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    In today’s episode, I’m trying something new. So, what I’ve got here is a Rode Wireless Go transmitter. You see a lot of folks who have transmitters like this. And what I’ve done is gotten a cheap power bank—I mean, it’s like some no-name power bank—and a USB-C to C male-to-male connector. And what I’ve done here is essentially turn this into a handheld microphone.

    Now, to be clear, this is just about the worst possible way to use a lavalier microphone. A lavalier microphone really should be clipped to you to take advantage of the—the way it’s—the microphone’s designed to work. But you do see a lot of people using microphones like this, like a lot of—just holding them in my hand. I can’t tell you the number of YouTubers I’ve seen holding their lavalier microphone like this where they’re spitting on it, making a whole bunch of noise with the microphone. Not ideal.

    So, the next best thing is to use it—use it a bit more acoustically the way it’s designed to work. It’s designed to work in a sort of a bubble area. So, one of the things that—one of the reasons why you have it down here is, A, the convenience, but B, this is out of the plosive range. The—that—those—the B and P plosive sounds—when it’s down here on your chest, you’re not picking that up. When you’re holding it in front of you like this, you’re spitting, essentially, right into the microphone, which is great if doing a rap battle, not so great for trying to make decent audio.

    By having it on a handheld of some kind, you’re kind of getting the best of both worlds where you’re—I’m aiming it at my mouth because that’s—that’s the way it’s supposed to work—but I’m also not having it in the line of where the air is coming out of my mouth.

    So, I would suggest, if you’re going to use these things in a handheld way instead of the way they were designed to be used, that you consider a very simple hack like this. Now, Rode, the company that makes this, does sell a handheld device to hold these things like a broadcast microphone. It’s a 29 piece of plastic. That’s all it is, just a piece of plastic. You could print that yourself on if you had a 3D printer. I decided I would go the next best thing, which is to use a power bank so that while I’m holding this thing and using the microphone incorrectly, I’m at least charging it and at least providing power to the microphone so that it’s—it’s usable.

    And of course, the other end is directly connected to my computer. This would be connected to your phone or your camera or whatever. So, it’s kind of a fun little hack. I’m going to be testing this out at MAICON, the Marketing AI Conference. I’m traveling this week for it, but I wanted to do a field test—well, not a field test, a lab test at home first to make sure that this sounds okay, because if this sounds like garbage, obviously, I’m not going to bother packing it. I’m pretty sure this is going to sound better than—better than talking into it like this.

    So, that would be my advice. If you’re going to have lavalier mics, rig up a little system like this with a USB-C male-to-male connector and a power bank. This Rode piece of plastic that does nothing is29. This whole thing together was like $17, and it works just as well, has some additional benefits, and allows you to—to use these microphones in—in ways that are closer to the way they’re meant to be used.

    That’s going to do it for this episode. Thanks for tuning in. We’ll talk to you on the next one. If you enjoyed this video, please hit the like button.

    Christopher Penn 0:00

    In today’s episode, we’re continuing our experimentation with Adobe podcast specifically going to be testing it with a variety of different microphones.

    Last time, we tested it just with the onboard audio in a variety of noisy situations.

    And today, we’re going to test moderate background noise, there’s a fan going.

    So there’s a little bit of fan noise.

    And we’re going to test it against a whole bunch of microphones, we’re going to have microphones like the Bose QC AirPods, the Apple AirPods, version one and two, the original Bose headphones, the we’re going to test out these aero packs open comm they have little boom mic, we have the David Clark helicopter headset, which sounds like normally sounds like a instead of a tin can, and the anchor q 45.

    Now what we’re going to do is we’re going to record a few sentences connecting each of these devices to the phone and recording some video and the associated audio that goes with it.

    Generally speaking, generally speaking, you want to record at the best equipment possible.

    That’s why I’m recording this introduction with the Shure SMS seven be great sound in means less work for the algorithm to do for the reconstruction of your audio.

    And that’s a really important point, when you listen to the output that Adobe podcast puts out from its enhanced settings.

    It’s not cleaning up the noise, it is reconstructing your voice based on the input.

    So here’s that’s how it can get rid of background noise that would otherwise be interfering with your voice.

    If you do traditional audio editing.

    In something like Adobe Audition, yeah, you can do noise reduction, noise gates, compressors and all those things.

    But you’re still going to have that background noise, particularly at frequencies where the human voice also operates.

    The way I think and I don’t have confirmation because I’ve not talked to anyone at Adobe about this.

    But the way I think it’s working is it’s understanding what is your voice, basically using that against a pre trained neural network model, some kind of artificial intelligence to reconstruct your voice from scratch.

    And that’s why there are glitches here and there.

    And that’s also why I fed it.

    So audio from a trade show very loud background, but a lot of other human voices, and the algorithm just imploded, right? It was not able to, to construct anything useful, whereas traditional noise reduction techniques might have been able to salvage at least something.

    Either way, that background noise with all those other human voices really threw it for a loop.

    So I’m guessing that that’s how that worked.

    So let’s go ahead and do these tests.

    We’re going to record some video with each of these and then come back to see which one sounds the best.

    Test number one straight audio right off the iPhone using the built in microphone.

    I’m going about a foot away from the mic here talking normally, we’re going to see what Adobe podcast does reconstructing this to sound as close to studio quality as possible.

    Test number one stream audio right off the iPhone using the built in microphone.

    I’m about a foot away from the mic here talking normally, we’re gonna see what Adobe podcast does for reconstructing this to sound as close to studio quality as possible.

    Okay, we’ve got the first generation

    Christopher Penn 3:11

    Apple AirPods pros, and this is generation one.

    Again, I’m still the same distance all of it doesn’t matter.

    These are using the onboard microphones and the AirPods.

    Want to see how they sound then we’re going to put it through a Dolby podcast to see what it can clean up.

    Okay, we’ve

    Christopher Penn 3:26

    got the first generation Apple AirPods.

    Pros, this is generation one.

    Again, I’m still the same distance Oh, it doesn’t matter.

    These are using the onboard microphones and the AirPods want to see how they sound then we’re going to put it through Adobe podcast to see what it can clean up.

    Okay, we’ve

    Christopher Penn 3:42

    got the Apple AirPods revision two.

    So this is the second generation AirPods they all already we already know that they have a better microphone setup thanks to the h2 Processors and Things on board.

    But let’s see now again still another great environment.

    Let’s see how this sounds after Adobe podcast cleans it up.

    Okay, we’ve

    Christopher Penn 3:59

    got the Apple AirPods revision two so this is the second generation AirPods they all already we already know that they have a better microphone so thanks to the h2 processors and things like that.

    But let’s see now again still above a great environment.

    We’re gonna see how this sound after Adobe podcast cleans it up.

    Christopher Penn 4:17

    Okay, we’ve got the first generation Bose QC earbuds This is the gen one these are actually my favorites because they’re the cases wirelessly charges I don’t know why the case doesn’t on version two.

    And to me at least the ear buds feel like they feel better but whatever.

    Anyway, we want to see how the microphone sounds on these and then see how it sounds we wash it through Adobe podcast is the Bose QC your buds gen one.

    Christopher Penn 4:41

    Okay, we’ve got the first generation Bose QC earbuds the gen one these are actually my favorites because they’re the case is wirelessly charges.

    I don’t know whether a staff member to and to me at least the earbuds feel like they feel better but you know, whatever.

    Anyway, we want to see how the microphone On sound zombies and then see how it sounds.

    We wash it through Adobe podcast.

    So this is the Bose QC Yurbuds gen one.

    Okay, we have the Bose QC earbuds Gen twos is the second generation product supposedly has better microphones and all that jazz you know the usual marketing stuff so we’re gonna see again how this sounds, you know moderately noisy environment and then how Adobe podcast cleans it up.

    So Bose QC earbuds generation two, okay, we have the Bose QC earbuds gen two so this is the second generation product supposedly has better microphones and all that jazz, you know, the usual marketing steps we’re gonna see again, how this sounds, you know, moderately noisy environment and then how Adobe podcast cleans it up.

    So Bose QC earbuds generation two, this is the David Clark H 30.

    I think the BT 30 is I don’t remember what model number it is.

    But these are the passive noise cancelling headphones if you they look familiar, it’s because these are basically headphones meant for airplanes and helicopters.

    They just made a Bluetooth version for headphone nerds like me, I guess so that we could wear something it looks like we belong in a helicopter.

    But yeah, at our desks.

    It is fantastic for flying.

    Obviously, if you want noise cancelling that works all the time.

    These are the ones you get downside, they’re super heavy, and they’re really big and cumbersome, but they have good battery life.

    Anyway, the point is to test the microphone, the boom mic on this, which probably sounds like you would helicopter would and then put that through Adobe podcast.

    So these are the David Clark, BT 30 Something brothers.

    This is the David Clark 830 I think it’s the the BT 30 I don’t remember what model number it is.

    But these are the passive noise cancelling headphones.

    If you look familiar, it’s because these are basically headphones meant for airplanes and helicopters.

    They just made a Bluetooth version for headphone nerds like me, I guess so that we can wear something it looks like we belong in a helicopter.

    But yeah, at our desks.

    It is fantastic for flying.

    Obviously, if you want noise cancelling that works all the time.

    These the ones who get downside, they’re super heavy, and they’re really big and cumbersome, but they have good battery life.

    Anyway, the point is to test the microphone, the boom mic on this, which probably sounds like you would a helicopter would and then put that through Adobe podcast.

    So these are the David Clark, BT 30 Something brothers.

    Okay, this is the aftershocks open calm.

    So this is a Bluetooth bone conductance headphone that leaves your ears open.

    So you can hear your surroundings and actually transmits most of the sounds through your your phones.

    It’s got the boom mic on it.

    And that’s what we’re testing today.

    These, by the way are what I wear for when I’m running outside because you can actually hear the traffic around you and not get hit by a car.

    But the microphone we care about today.

    So let’s see how this sounds.

    And then what it sounds like after we put it through Adobe podcast.

    Okay, this is the aftershocks open calm.

    So this is a Bluetooth bone conductance headphone that leaves your ears open.

    So you can hear your surroundings and track your transmits most of the sound through your your bones.

    It’s got the boom mic on it.

    And that’s what we’re testing today.

    These, by the way are what I wear for when I’m running outside because you can actually hear the traffic around you and not get hit by a car.

    But the microphone we care about today.

    So let’s see how that sounds.

    And then what it sounds like after we put it through Adobe podcast.

    Christopher Penn 8:13

    Okay, these are the anchor sound core sound space Do you forgive I don’t even remember the name of the product.

    Because these are the budget noise cancelling headphones are actually really good.

    They’re actually better than the older generation of the Bose ones.

    But again, today we’re testing up a microphone to see how the microphone sounds on these.

    And then we’re going to put it through Adobe podcast to see if Adobe podcast can clean up whatever the sound is.

    I’ve actually never tested these, the microphone on these.

    So I’m curious to sound here it sounds like so this is the anchor sound something or other q 45.

    Okay, these

    Christopher Penn 8:44

    are the anchor sound core sound space.

    Usually, if I don’t remember the name of the product, this, these are the budget noise cancelling headphones are actually really good.

    They’re actually better than the older generation of the Bose ones.

    But again, today we’re testing up a microphone to see how the microphone sounds on these.

    And then we’re going to put it through Adobe podcast to see if Adobe podcast can clean up whatever the sound is.

    I’ve actually never tested these the microphone on me.

    So I’m curious to hear what sounds like so this is the anchor sound something rather cute 45 All right, that was a lot.

    So we can draw a couple of conclusions from this one.

    I clearly have a problem.

    At least when it comes to headphones.

    They are one of my one of my devices.

    One of my addictions along with keyboards, too.

    As with everything, the better the quality going in the better quality coming out.

    We heard on some of the headsets like the David Clarke and the aftershocks.

    The audio quality going into Adobe podcast was atrocious.

    Right.

    So of course it came back it did the best it could and it did better than probably you’d be able to do manually.

    But it wasn’t.

    It wasn’t the level of quality you would expect from something was truly recorded in a studio.

    The Bose headphones the first generation QC stood Okay the second generation will not so much because again, for some strange reason that product got worse in a second generation than its first, the anchor headphones reasonably well, right though that microphone is pretty capable, the AirPods.

    Version one was good to version two was better.

    Here’s the funny thing, though, of all of the microphones that produced a good outcome, a good output from Adobe podcast, the one on the phone did surprisingly well, it did surprisingly, well, somewhat show them like, Huh, that’s interesting that that would have those different capabilities.

    So I think what we can draw, in terms of conclusions are a couple things.

    Number one, if you have to record on the go, maybe you’re at a conference or a trade show, or you’re traveling or whatnot, and you want to get some ideas down, use the best mic available to you, right? For this test, that was the BS, the the Apple AirPods Pro, version two, followed by the phone itself, the phone itself, and that’s really important.

    The reason that’s really important is that as long as the background doesn’t contain human other human voice is in any significant volume.

    If you’re just out and about and you want to jot something down, just turn on your phone, hit record, and then you know that later on, you can clean it up in in post processing.

    And that’s, that’s critical.

    Because we all want to sound our best, right? We all want to look our best, we all want to sound our best.

    But if we don’t have to lug a whole bunch of extra gear with us, there’s some value in that, right there is some value in being able to just have your phone with you, knowing that you can clean it up later.

    Now this is a high stakes production where you know, it’s a feature film or something Yes, of course, you want the best gear, you’re not going to skimp you’re going to get a shotgun mic or your boom mic or your your concealed lavalier mic, whatever the case may be, because you want the best quality audio.

    But if it’s not mission critical, if it’s day in a life, if it is a video blog, like this, your phone and have as quiet an environment as you can make it within reason is good enough, right.

    So when I travel, for example, and I go on the road, I don’t have to lug all this gear with me now if I want to record something in my hotel room, and have it sound good because I can just use the microphone right on my phone.

    And it will still sound great, right as long as there’s not like you know, mariachi band outside the door, if there is other things going on, but that’s freeing, that is freeing to know that as long as I’ve got my phone with me at a quiet place, I can continue to make good quality content with great quality audio with nothing more than the phone itself.

    So I would encourage you to do this with your own gear because I’ve got a specific phone model and all this stuff but do with all your own gear, test this out with your own stuff and see which combinations of the gear you only deliver the best sound without having the full studio setup using a tool like Adobe podcast.

    You might be surprised.

    You might be delighted and then you might find out Yeah, I don’t need to haul around tons and tons of gear just to sound my best.

    Thanks for tuning in.

    We’ll talk to you soon.

    You Ask, I Answer: Audio Quality Hardware vs Software?

    Todd asks, “When it comes to audio quality, what’s more important, software or hardware?”

    There is no cut and dried answer to the question of whether software or hardware is more important for audio quality. It depends on the relative quality of the stuff you’ve already got, and what you’re using it for. If you have good quality software and know how to use it, you can do a lot with it. However, if the audio quality you’re working with is poor to begin with, there’s only so much software can do. In general, try to get the best microphone you can afford and learn how to use it properly.

    In today’s episode, Todd asks, when it comes to audio quality? What’s more important software or hardware? The answer to this question is, it depends.

    It depends on the relative quality of the stuff you’ve already got.

    So if you have a really good piece of software and you know how to use it like Adobe Audition, you can do a lot with that, right? That is, that’s like an appliance.

    A nice high end appliance, you can do a lot with the software, you can do noise reduction, sound removal, amplification, compression, all the the audio engineering techniques that anyone with a good audio engineering background should know.

    However, there is a lower limit to what you can do with the software.

    Because if the the audio quality that you have going in is so bad, there’s only so much software can do.

    Software cannot fix things that are just flat out unlistenable.

    So for example, if you are walking around at an event, and you’ve just you’re just holding your phone up in the air, right with the voice memos on, you’re not going to get great audio quality, it’s going to be very, very difficult to engineer that into something that sounds good.

    Yes, you can reduce some of the noise.

    But things like reverberation echoing sounds very, very difficult to get rid of that.

    If you have a decent audio recorder, for example, and you just use it improperly.

    Again, there’s not going to be much you can do about that.

    I remember the first time I met my friend, Chris Brogan, at an event in BarCamp.

    Boston, he had a little AI river audio recording device not much bigger than this, this microphone.

    And he was trying to record the audio from sessions and was putting this little mp3 recorder on top of the speaker cabinets in in the room.

    Now, if you know anything about if you don’t know anything about audio recording, that’s about the worst possible way to record audio because speaker cabinets themselves are muffled, the audio coming out of them is not great.

    It’s fairly distorted.

    And you get a lot of clipping.

    Clipping is what happens when the signal to noise that you’re recording is greater than what the device you’re recording on, it can handle.

    Think of it like a cup of water, right? Your microphone that you’re using can only take in so much noise after a certain amount it overflows, right and you’ve got more noise flowing in, then you have cup, you’ve got a mess.

    The same thing is true with audio gear.

    This microphone I’m using right here, this is an SM seven beat.

    It is fairly robust, right it can it can tolerate a lot of loudness.

    But if I just sit here and just scream at the top of my lungs, it’s gonna peak out and it’s going to go past what the microphone can record.

    And like photography, you can boost low signal, right? You can make quiet sounds a little bit louder or substantially louder.

    You cannot recover from sounds that are blown out just like you can’t recover from photos that are overexposed beyond a certain point there’s because the information simply isn’t there.

    If I yell really loud, or you know going back to the glass example, if you overflow a cup, you can’t do anything with all the water that has fallen out right you can only work with what’s in the cup and what’s in the cup may not be all the sound so your your software does matter.

    But when it comes to audio quality, try to get the best microphone that you can afford within reason and try to make sure that you’re using it properly.

    There are all sorts of microphones that you can buy.

    So if you have any examples, one of my favorites is this little boom mic quote from a company called V moda and all it is his little mic that plugs into a headset and use where this news Hawk right into it and that is believe it or not for a lot of people going to be more than enough microphone there are other mics there’s so many so many on the marketplace.

    Anchors power cast microphone is pretty good for 40 bucks.

    Logitech yeti microphones are overpriced at I think they’re at 130.

    Now they’re overpriced for what they are.

    The SM seven B is 499.

    It is it is expensive, but it is better sound.

    Think of your hardware.

    Think of your hardware like ingredients right? If your software is like an appliance your hardware is like an ingredient A generator, right, the sound that comes out of this is your raw materials, the better the hardware, the nicer the raw materials.

    And then the nice the raw materials, the more you can do with it, right.

    So if you have raw materials such as salad garbage, right, and just like if someone drops off rotten produce at your house, there’s only so much you can do with that, like you can compost it.

    But you can’t really cook with it, you’re not going to no amount of great appliances is going to turn rotten cabbage into anything other than rotten cabbage.

    So with microphones, in particular, get the best microphone that you can afford, for the purposes that you’re going to be using it.

    And then again, learn how to use it, this SM seven B, this is a dynamic mic, it has a lot of things going forward.

    But one of the things that you have to know about mics like this is that they require you to be really close to them.

    So just this I’m now about a foot away.

    And you can tell there’s a big difference in the quality of the sound even though it’s the same same $499 microphone, and if I’m using it the wrong way.

    It you may as well not be using it at all right now again, you can fix that particular mistake to a degree in software, but it’s better to know how to use the technology.

    A, an expensive piece of hardware used improperly is a bigger waste, right? So get the technology that you know how to use that you can afford to use that you can afford to use well, that little headset microphone.

    It’s pretty foolproof.

    It’s pretty foolproof.

    So if you use that, and you don’t get one of these things, you’ll be better off if you don’t know how to use this, but you do not have to use a headset mic, you’re gonna get better sound of the headset mic because you know how to use it.

    So that’s the answer.

    There is no cut and dried answer.

    It depends on what you’ve got depends on your use case, your intended outcome and what you’re capable of from a knowledge perspective, but it’s a really good question given the prevalence of now podcasters and live streamers and YouTubers and Tiktok errs.

    Everybody in their cousin is generating content with these more sophisticated tools, but you got to know how to use them.

  • Bakeoff: Apple AirPods Pro Gen 1 vs Gen 2 vs Leaf Blower

    In this episode, I test out the new Apple AirPods Pro Generation 2 versus the previous generation and the Bose QC Earbuds Generation 1 for noise cancellation and microphone quality in the most absurd conditions: with a leaf blower.

    The new Apple AirPods Pro are pretty impressive. The noise cancellation is good, the microphone is good, and they’re comfortable.

    This review is entirely unsolicited and I paid for everything out of pocket.

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    Christopher Penn 0:00

    So today we’re gonna test out the new Apple AirPods the second generation pro versus the first generation for noise cancellation.

    And for for mic stuff I’m doing in the car because cars are one of the best places to do this sort of stuff because they’re, they’re almost, you know sound insulated a little bit.

    So let’s get started.

    Here’s what we’re going to do, we’re going to use this little sleep machine noisemaker and I’m also going to turn on the sound detection on my Apple watch.

    So right now okay, so let’s do this.

    Let’s start with a benchmark here 34 decibels with nothing.

    So let’s do 10 clicks on here 1-234-567-8910 It’s about 42 decibels, so about 10 More

    1-234-567-8910 58 decibels 1-234-567-8910.

    About 70.

    So 4458 and seven years sort of the where this thing goes.

    So that’s those are three levels.

    Let’s go ahead and do AirPods number one

    Unknown Speaker 1:40

    Okay, here we go.

    Christopher Penn 1:41

    This is first 1041

    Unknown Speaker 1:42

    decibels

    Christopher Penn 1:57

    I can just start to hear it now.

    Unknown Speaker 2:03

    54 decibels definitely hear it now 69 decibels.

    So there’s the first AirPods take those out.

    Christopher Penn 2:24

    Okay, got the second set of AirPods.

    And now Now this is where it’s saying noise levels reduced by AirPods on the watch.

    So I can’t actually get a good reading but I can count the number of clicks like we’ve been doing.

    So here we go first 10 clicks

    now it’s saying on here 24 decibels noise reduced by AirPods.

    That’s firsthand.

    I can feel it.

    I can’t really hear it.

    Unknown Speaker 2:51

    Let’s go to the second 10.

    I can hear it.

    But it’s definitely quieter than the others that are AirPods.

    Okay, can I more feel up in here, I can tell there’s a white noise that was taken up there instead of 10.

    Unknown Speaker 3:16

    Yep, now this is saying on here.

    Noise level 4748 decibels, so it’s at 70.

    So that’s a pretty big reduction bias

    Christopher Penn 3:35

    so when it’s a max going here, this is about 70 decibels.

    When it’s guys cranked up and on here it’s saying 4647 So it’s chopping about 25 decibels off which is pretty impressive.

    That’s up there with actual hearing protection right your average hearing protection noise reduction levels between 20 and 30 decibels depending on how it adjusts.

    That’s That’s pretty impressive.

    For calibration.

    Let’s go ahead and do the Bose QC your

    Unknown Speaker 4:02

    bucks now.

    Now I switched over to the Bose QC earbuds the

    Christopher Penn 4:10

    first generation ones so let’s see how we’re doing here

    Unknown Speaker 4:18

    Okay, there we go.

    45 hear it now 55 That’s somebody I heard on 55 on that one.

    So this was the third third way in, alright.

    Christopher Penn 4:53

    Okay, next what we’re gonna do is we’re going to try testing this microphones against them.

    When I’ve done this.

    I’ve said Have a leaf blower on my grill here, I’m just gonna stand roughly here to start winding up as long as it sounds, it’s gonna be both the wind and the noise

    Unknown Speaker 5:27

    Okay, next up, we have the Generation One AirPods got some nice cross breeze here, but we’ll see how the sounds of the gen one AirPods.

    Christopher Penn 5:35

    Okay, now we have the generation to AirPods we’ll see how these sound.

    So that was the test to see how each of these three microphones sound in really adverse conditions, you probably wouldn’t be standing in front of a leaf blower, but if you had to be, what’s the other sound? All right, well, there you have it.

    That was the noise cancellation test inside the vehicle, and then the microphone test.

    In terms of my thoughts, these are pretty impressive.

    These are pretty impressive.

    The noise cancellation was good.

    I felt like they were definitely better than the Gen ones.

    In terms of the noise cancellation, I could pick up and detect the noise right around 5560 decibels.

    But it was definitely more muted with the generation twos versus the generation ones for the same amount of noise.

    So it was detectable.

    But it was less but it was still there.

    And the Bose around the same level as well.

    The microphones is where these things stand out.

    The gen one microphone is okay.

    Right? It’s It’s decent, the Bose QC ear buds microphones is awful.

    It you sound like you’re in a tin can all the time.

    These, the microphone sounds good if you listen to carefully just between the gen one and gen two is a big difference in the microphone.

    The quality to the point where if I was out and about and I was going to shoot some video, impromptu I hadn’t planned to shoot or anything like that.

    The mic on these is good, right? It’s not as good as I can with the wireless lavalier that I’m using the RODE Lavalier.

    But for out and about, this is good enough, this is good enough to get good quality audio that you would be happy to have in your YouTube videos or wherever else as you use video.

    The other thing I think is really impressive about these is the noise cancellation having the meter on the Apple Watch that tells you how much it’s cutting the noise by 2025 decibels.

    That is at the level of actual hearing protection, right when you start cutting 20 to 25 decibels, you’re at a point where you no real hearing protection, that you know your earplugs cuts that noise down.

    So if you are again on the road at an event at a concert or something, and it suddenly gets really loud, pull these guys out and put them in your ears and you will reduce the amount of noise and potentially take dangerous noise levels back down to safe noise levels.

    That’s pretty cool.

    Right? So combination of hearing protection, good microphone, good microphone, and good noise cancellation? Is it as good as Apple says? Is it double the previous versions? Not really.

    You know, I would expect double to be because Decibels are logarithmic, I expect double to be you know, five or six decibels greater in terms of the ability to cut they cut a route and same route but they cut it differently so I can detect it.

    But it’s less loud the same decibel levels.

    If I had to pick one of the three as my every day, this would be it.

    This is it now because we paid for these that they’re better than the Bose QC additional ones.

    Now I have not tested any of the Bose QC earbuds, generation twos.

    They just came out and having heard this now it’s a tough sell.

    It is a tough sell because they’re more expensive at 50 bucks more expensive than these.

    They don’t do everything the apple’s devices do you know the instant pairings stuff like that.

    And the noise cancellation on these is really good.

    Like it’s, it’s better than the Gen ones for the Bose side of things.

    And it’s good enough that I would be happy just with this on an airplane, I wouldn’t need to use the other ones which do better on an airplane than the Gen ones do with this.

    This is pretty good.

    So in terms of which one if I had to just pick one, this is the gen two AirPods pro Apple did an amazing job with these.

    And while it might not live up to marketing’s claims, it certainly lives up to my expectations about what a second generation product should be able to do.

    And, yeah, I like it.

    I like it a whole bunch.

    So that’s the show, I would love to hear your experiences if you’re testing out this gear to if you got a better way of doing some of these tests.

    Certainly the leaf blower test.

    I mean, that was just ridiculous, right? No microphone is going to do well in that environment where we’re pumping 650 cubic feet of air per second at these microphones, but I will say having reviewed the footage,

    it is most intelligible with these it’s still not intelligible, right? It’s you know, it’s like standing inside of a tornado.

    It’s still not intelligible.

    But the other shoe sets the version ones on the Bose QC UCS.

    You couldn’t hear anything.

    I was just pure noise these you could make out some of my voice.

    And that again, pretty impressive for a ridiculous test condition.

    So that’s, that’s the show.

    like to hear your thoughts, leave them in the comments.

    Thanks for tuning in.

    I’ll talk to you soon.

    Mitch asks, “With the return of the Levelator, what’s the best audio leveling solution for podcasting?”

    For those unfamiliar, the Levelator is a piece of software that promises one-click cleanup of audio to ready it for podcasting. Other solutions, such as Auphonic, do similar tasks – but the Levelator is free. And for those who have it, tools like Adobe Audition can bring extra polish but are decidedly not one-click.

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    In today’s episode, Mitch asks, with the return of the Levelator.

    What is the best audio leveling solution for podcasting? Well, for those who are unfamiliar, but Levelator is a piece of software that promises sort of one click cleanup of audio to Reddit for podcasting.

    There are other solutions.

    Levelator stopped working for a while because of various operating system updates and the fact that the software vendor basically has moved on to other things.

    But there are still folks who are committed to maintaining it, and they do.

    And so, other tools like Auphonic, for example, do similar tasks, but the Levelator is free.

    And obviously, for those who own it tools, like Adobe Audition can bring a lot of extra Polish but not really the one click solution.

    So what we wanted to look at today is how do these things sound.

    So let’s go ahead and flip things over here.

    And we’re going to put these audio tracks in.

    So let’s start with this first.

    Here.

    Let’s go ahead and play this.

    The quick brown fox jumped over the lazy dogs.

    The quick brown fox jumped over the lazy dogs.

    The quick brown fox jumped over the lazy dogs.

    The quick brown fox jumped over the lazy dogs.

    So that was this microphone is the first on the V moda boom headset is the second one, the apple AirPods Pro is the third one and then just the onboard laptop sound I wanted to do that because I wanted to have it for different types of audio sources to see how each one sounds.

    Now with the tool I’m using for video Camtasia it does have a built in leveler.

    So let’s look at that one first.

    You can see there’s already a bit of a difference the these the spectrogram here is a little more dense, a little more colorful.

    Let’s go ahead and listen to this.

    This is Camtasia quick brown fox jumped over the lazy dogs.

    The quick brown fox jumped over the lazy dogs.

    The quick brown fox jumps over the lazy dogs, The quick brown fox jumped over the lazy dogs.

    Okay, so that was Camtasia good, right? Not great yet, but okay, not too bad.

    Let’s now listen to Auphonic which is one of the more popular tools out there.

    Hang on for a second here.

    There we go.

    The quick brown fox jumped over the lazy dogs.

    The quick brown fox jumped over the lazy dogs.

    The quick brown fox jumped over the lazy dogs.

    The quick brown fox jumped over the lazy dogs.

    You can see in the spectrogram that the the colors there are brighter and more intense.

    If I click back to the original you can see there’s definitely a big difference right? It’s a much bigger difference than you see with Camtasia Auphonic brings a lot more vocal ohms and it’s at the right volume level.

    For podcasts which is a target loudness of minus 16 Fs, which you can see down here in the corner.

    Now let’s go ahead and look at the Levelator.

    And here we go.

    The quick brown fox jumped over the lazy dogs, The quick brown fox jumped over the lazy dogs, The quick brown fox jumped over the lazy dogs, they’re quick brown fox jumped over the lazy dogs.

    Again, very similar sound to Auphonic.

    Right? It’s there is a, a qualitative difference between this one here you can see there’s less of the purple fringing here in Auphonic.

    There’s a bit more of that, in in with Levelator pulled together.

    So the Auphonic seems to have a little bit better noise reduction.

    But when you look at the the sort of the colorful sections here, there the Levelator is seems to be doing a better job of enriching some of the tones now Should you use? Well, if you can run the Levelator on your machine, if you have a Mac, and you’ve gotten it out of the App Store, and I believe it’s still available for Windows, and you’ve got a single audio file that you’re trying to, to work with, it’s kind of hard to argue with this.

    And it’s free.

    It’s not as good at things like the the noise reduction, as Auphonic.

    But it also is free, right? And it’s still better than say Camtasia is built in level which is not great.

    Or and it’s all of it is better than what you get when you just have the raw audio file by itself.

    So, conclusions if you are if you’ve already bought Auphonic keep using it, right? Why wouldn’t you keep using the thing that you paid for? If you had have not bought it? Look at the Levelator it again, it’s free and it does a really good job.

    The other levels and tools that are available, like if you wanted to do something in audition, you could there’s certainly ways to do all that what these tools do as as set of new tricks if you want a very distinctive sound, but honestly, for a lot of people, that’s a heck of a lot of work and adds a lot of production time.

    Whereas dragging and dropping a file onto another app, really definitely is the way to go.

    So, in conclusion, should you use one of these tools or others? It depends on what you’ve got and what you’ve already bought.

    I would say that in terms of what they output Auphonic the Levelator put out very close quality, and their quality is both better than not doing it at all.

    So pick whichever one works for you, and and do that.

    So a good question, Mitch.

    You Ask, I Answer: Recommended Setup for Webinars?

    Paul asks, “What’s your recommended audio, video, and lighting setup for webinars and events?”

    Great question. As David Tames once taught, great video begins with great audio. Get the mic near your mouth!

    Lighting will do more to improve video quality than almost any camera, as long as the camera isn’t absolute junk. Go for a three point lighting system – and it’s okay to use cheap lights.

    In today’s episode Paul asks, What’s your recommended audio video and lighting setup for webinars and events? This is a great question and it’s less about the gear and more about how you use the gear like cooking for example, a master chef can do amazing things with the stuff in anybody’s household whereas someone who’s incompetent can be put in a five star kitchen and still burn water.

    So let’s talk about a few things number one audio as David to mess over at Keno It teaches great video begins with great audio, you want to get the microphone near your mouth.

    Now, if you’re using a boom mic like this, which is a this particular mic because it’s a cardioid mic.

    It picks up the sound right here, no sound here.

    But you have to know the kind of microphone you’re using.

    There are some microphones where the element is not on the top That’s actually on the side.

    And so, read the manual to make sure where your microphones element is actually picking up your voice.

    Now with a microphone like this, you want to test you turn on a video recorder like this, and test to see how you sound because it will sound different in different places.

    Let’s bring up this diagram here.

    You see, there’s nine numbers I put on this diagram, the nine different places you could position this mic, what you want to do is turn on a video recorder like this and test it, position one, position two, this is probably you’ll never use this position three, position for position five, position six, position seven, position eight, position nine.

    And then you’ll go back and watch the video listen to the video and see how each position sounds get a sense of Okay, that’s where I want my mic.

    If you don’t have a windscreen on your mic, you want one because what you don’t want to hear is breathing.

    Most of you look back at this chart, position five and position eight Where this mic tends to work best but position five you will hear breathing even with a windscreen you’ll still hear it position eight down here by your chin with is still aiming at your mouth is the probably the best position for this mic.

    Regardless of the microphone type you own like you know you have this is an example of a boom mic you know positions two and five are probably the best positions for it.

    You want near your mouth and you want to aim at your mouth wherever the microphone element is aimed at at your mouth.

    So that’s audio.

    Again, you don’t need expensive gear you just need to use it well use it properly.

    To lighting will do more to improve video quality then pretty much any camera people like what camera should I get you know what’s the best camera.

    If the light sucks, it doesn’t matter.

    You can even there are systems or software that you can use your smartphone as a webcam for for recording video.

    These cameras work great in Good in good light.

    In crap light, they work terribly.

    It’s one limitations of this type of camera.

    If you have a webcam either built into your computer or into into you have a separate one, again, great lighting matters.

    Let’s look at three examples.

    This is just a single overhead light, you can see looks terrible, right? This is an overhead light and the the, the ring light that is in my particular cameras.

    So there’s two points of light you can see it’s better.

    It’s better, but it’s not great.

    Now I have a cheap yard sale lamp I got it like off the side of the street somewhere for like $1 with a naked bulb on and nothing fancy just a standard light ball overhead at a 45 degree angle from me.

    This is I mean this is what you’re seeing me with this video on now you can see there’s a world difference even between the two point setup and a three point setup.

    So you want that three point lighting setup.

    Simple overhead light to fill up the background, right, a light in front of you and then this strong The overhead light that creates very pleasing shadows.

    Now, where you put the camera matters to, there’s fundamentally three levels, you can pull it out, you can put it at above your head.

    This is what looks like when people are looking up the camera looking down on you.

    There’s at or near eye level, which is where I prefer to have the camera.

    And then there’s people who put the camera super low where you’re looking up somebody’s nose.

    This is not a good look.

    Most laptops, if you’re using the webcam on the laptop, the laptop is down, looking up your nose.

    The angles are wrong, you it’s unflattering for some people, and it just looks weird.

    It it creates this impression the person is looking down upon you, right? This is not something you want.

    If you look at how, for example, most news broadcasts where they’re trying to portray the person in a neutral friendly light, it’s at eye level, you’re looking at a person II and you want to create that same impression.

    So if you have a laptop and you’re using the laptop Top as far as a camera source, stick something under it stick some books, milk crate, whatever you got anything to get it to roughly about eye level.

    Eye or just slightly above eye level is where like to aim things when you’re doing instructional things, if you’re doing a straight live stream, it’s okay to have a camera be dead center with you, right? This is this is me dead center.

    If you’re doing instructional stuff like this where you want to have space, try and have the camera slightly offset so that you have space to display images, picture and picture stuff if you’re doing that kind of thing.

    I also tend to personally like to have the camera at an angle you can see this is a standard bookshelf so you get the vertical lines, okay? But the horizontal lines are at an angle, it gives you depth and perspective.

    If you shoot against a straight background like where you’re just straight against the wall, the background doesn’t really pop out because there’s no depth.

    It’s just a big flat space, even if there’s books and decorations on it still looks very flat.

    So having your camera at an angle to your background creates a sense of depth and a sense of space.

    Be aware if you care about these things of what’s in your background too if you look down here you got a milk crate with some wires that are sticking out right if I was doing a segment where I was going to be on like broadcast TV, I might want to clean up some of that stuff right? When you’re on camera wear stuff that is not busy, right? We’re planes.

    Limited patterns, no plaid.

    Right? Oh, Paisley.

    Things that the cameras depending on the quality of the camera may not be able to pick up well.

    But again, it’s less about the gear and more about how you use the gear.

    Inexpensive lights like we’re talking.

    Go on Craigslist seems throwing away a free lamp, right.

    Simple, simple stuff.

    Keep it simple.

    And instead focus on how you’re using it.

    What angles the camera.

    Where’s the microphone? Though how you lighting the room that’s going to give you the most mileage for the gear you’ve got to create better quality video.

    And obviously if you want to spend money and you’ve got the money to spend on high end gear, great, go for it, but take care of the surroundings and take care of the environment.

    First, it’s going to give you a much better bang for the buck.

    So good questions on this fun and challenging topic.

    Live Video any kind of video is is tough for a lot of people because they’re very concerned about how they portray themselves.

    totally get it.

    But use these tips to make the most of what you’ve got.

  • You Ask, I Answer: Leveling Software for Podcasting?

    You Ask, I Answer: Leveling Software for Podcasting?

    Mitch asks, “What’s the best leveling software for podcasting? What are the recommended techniques and settings?”

    Way back in the day, everyone and their cousin used something called the Levelator. That has since been discontinued; in its place, I use the desktop edition of Auphonic, the multitrack edition. Watch the video for details and a walkthrough.

    Machine-Generated Transcript

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    in today’s episode, Mitch asks, What’s the best leveling software for podcast? And what are the recommended techniques and settings? So leveling? For those who aren’t familiar is the process of taking an audio file and making the volume consistent.

    When you’re doing a podcast when you’re doing any kind of video, or audio, you want the experience to be evenly normalized so that it’s not loud in some parts and quiet in other parts.

    you’ve likely had this experience if you’ve watched regular television, where you’re watching a show and then suddenly a commercial comes on.

    It gets way louder like whoa, that’s that was a little intense.

    Leveling fixes that leveling.

    Also, depending on on how you use the software can help make audio easier to hear, particularly for things like noisy environments like a commute, a gym, etc.

    Not much of a problem.

    home because people can just turn the volume.

    But if you’re trying to listen and deal with background noise of any kind, leveling helps fix that.

    Way back in the day, in the early days of podcasting, this was a great piece of software from the conversations that were called the level later.

    That has since been discontinued.

    It’s been discontinued for a couple years.

    So the question a lot of folks have is, what’s the replacement? The software that I use is one called off phonic.

    Now there’s a bunch of different versions of this all phonic you can find over at all phonic calm.

    And they they have two different versions.

    They have their their web service version, and then they have desktop applications.

    I am a big fan of desktop applications, because software is a service, you know, upload to the web and do stuff like that is fine for some applications.

    It’s not my favorite.

    I would rather have a piece of software that runs on my desk that I can use.

    So how does this thing work? I use the most Track addition, there’s two desktop additions, there’s a single file addition.

    And then there’s a multitrack multitrack, obviously by its name requires you to have at least two audio files that you want to level, both independently and together, merge them together into one.

    If you do any kind of recording where you are recording two different tracks, for example, using software like audio hijack audio hijack is a fantastic piece of software that allows you to record one microphone and then and then like your your Skype or zoom or Google Hangout session, record the second one that gives you two different audio files that you then have to merge together.

    If you only record a single audio file, a you’re playing with fire, and B, you’d want the single track desktop edition.

    So let’s look at how this works.

    When you first jump into all phonic you get this environment here now, caveat, if you do only record one off audio file at a time but you want the flexibility of someday maybe needing to be able to merge two together, I would use the multitrack edition.

    And what I do in those cases is when I have a single file, I simply make a copy of it.

    And I have two files that work perfectly with the the multitrack edition.

    Generally speaking, when it comes to this sort of thing, let’s go ahead and do this.

    Let’s do this call it you ask an answer.

    And you get a chance to choose what algorithms you want.

    You want the adaptive leveler to make sure it’s turned on.

    You want cross gating, and you want the volume three is set to minus 16 l u Fs.

    There’s a whole bunch of interesting audio theory but for the moment, that’s generally the best setting.

    When it comes to each of the individual tracks, just make sure that adapter noise gate and high pass filter on noise and hum reduction is auto foreground is auto and the same is true for the second track.

    Then you have your own Track named whatever you want.

    Now again, if you want to get super technical, you can go into the preferences that specify all these different types of algorithm changes.

    Do you want it to be a WAV file? Do you want to be an mp3? Most people, most of the time, probably want a WAV file as the initial export when you’re taking like an interview that you’ve recorded, because in a lot of cases, you’re going to take that file and do something with it, you’re going to add music to it and things like that.

    The same for sample rates and bit depths and stuff.

    Chances are, you’re going to want to leave that as is you can change the directory.

    One thing that’s nice about what all phonic does is if you have intro and outro audio, you can automatically so it to the output file.

    I personally don’t do that I use an editor or Adobe Audition to do that because I would prefer to be able to manipulate it as needed.

    But if you wanted to put that into your workflow, give a consistent intro and outro that you always Use a never changes.

    This would be the way to do that.

    So let’s go ahead and go ahead and process these files.

    What it’s going to do is again, take those two files in this case, because they’re identical, you’ll just get the same thing out.

    It’s going to merge them together.

    Do all of the leveling the noise reduction, the sweetening of the audio to make it sound great.

    One catch, do not use this on music at all, every will, the level later had the same warnings it will sound like somebody sneezing into a tin can or something like that it just does not come out sounding good.

    And you can see here it’s starting to spit out the master track and the each track individually leveled.

    Now let’s look at what this has done.

    And this is the original file you can see here there are spots in this audio file which are really, you know, quiet spots that are that are particularly loud.

    Let’s go ahead and now open up the level file.

    And you can see it’s a lot.

    It’s a much better looking file.

    Let’s go back to this original one here.

    See how it’s not quite as rich or leveled and there’s some value in consistencies.

    In the revised version, things look a lot better, things look a lot cleaner, it’s ready to go.

    So to recap, make sure that you’ve got the correct addition for the way that you work.

    You do the workflow again, I like multitrack.

    I don’t mind a little workaround if you’ve only got one audio file but having that flexibility for recording from multiple pieces of software is is very helpful helpful.

    Minus 16 l u Fs is the setting you want adapt a level and cross gates.

    And then make sure that you’re the form background stuff and the noise and hum reduction or auto.

    You can do ducking you can specify which track should sound more prominent.

    I personally think that For what I’m using this for is in podcasting, you don’t need those things.

    Having again having the option to have it is terrific because you want that level of flexibility they are working on a version didn’t beta right now that is capable of dealing with music and fixing music to so if you’re a musician, you’ll want to keep your eye on that.

    Because that could be very interesting and very exciting for target loudness.

    Unless you’re doing something other than podcast, I was sick the minus 16 l u Fs, even if you’re going to use that audio with video so I will edit for example the audio from my speaking videos and use the exact same setting it sounds fine.

    It’s what people are used to hearing when it comes to podcasts.

  • The Great Mic Bakeoff: Microphones for Smartphone Video Creators

    The Great Mic Bakeoff: Microphones for Smartphone Video Creators

    As mentioned in this week’s newsletter, testing your gear to understand what’s good and what’s not in specific use cases is essential. In the Great Mic Bakeoff, we look at 8 different types of microphones for use in shooting video on your smartphone. Which microphone works best for overall audio quality? Which is the most portable? Which provides a good balance of portability and quality?

    The mics tested (see them all in this Amazon list):

    • Apple’s onboard mic on the iPhone X
    • V-Moda Boom mic
    • Kimafun wireless headworn mic
    • PoP lavalier mic
    • David Clark HBT-30
    • Bose QC-25
    • Aftershockz Aeropex
    • Apple AirPods

    The winners? For overall audio quality, the V-Moda sounds the best, but requires headphones to plug it into. For portability, Apple’s AirPods are a blend of okay audio quality with maximum portability.

    All the mics tested are available in this Amazon List. Disclosure: all links are affiliate links for which my company, Trust Insights, earns a commission and thus I benefit indirectly.

    Watch the video to hear audio samples from each of the mics.

    Machine-Generated Transcript

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    In today’s episode, one of the things that I advise people to do, in fact, this was the topic in my most recent email newsletter, about testing your gear, is to do those tests to figure out what gear works best in any environment.

    And so today, we’re going to do an eight way Bake Off with eight different kinds of microphones that plug into the smartphone with your choice.

    I’m using an iPhone but these obviously all work with pretty much any phone that has either a regular audio in jack or an adapter or Bluetooth connection.

    So we’re going to be testing things like the Bose QC 25 the whoops the David Clarke HPC 30s the arrow packs, the aftershocks, arrow packs, Apple’s iPods, the V moda boom mic all sorts of stuff to see which microphones sound the best from recording simple video from your phone.

    Links to the different microphones will put in the show notes and in the Amazon storefront, full disclosure, FTC disclosure, anything you buy is going to obviously generating a nonzero commission for my company TrustInsights.ai will receive some small financial benefit.

    None of these have been given to me, I had to buy them all.

    And so these are the these companies did not solicit these reviews in any way.

    We have the chemo fun 2.4 gigahertz microphone, a level your mic, so all sorts of different kinds of gear for different environments.

    What you’re going to hear is a test setup.

    Here in the office, off of the phone, I’ve got a desk fan running, that’s pretty decent amount of background noise so that you can hear the difference between the different types of microphones and not only in how much noise they make, how well they pick up my voice, but also whether they pick up the surrounding noise or not.

    So give a listen to this, enjoy it.

    And then if you hear it We’re seeing microphone that makes sense for specific use cases for your business by all means go go grab it and, and stuff.

    I’m not going to put any prices on stuff.

    It’s just we just want to listen to audio quality but I can say for the most part of it, the headsets are expensive but like the blog was like 12 bucks, the headsets are three or four or 500 depending on where you get them from.

    Anyway, watch the video.

    Listen to the differences in the microphones.

    I’m not going to edit the audio at all so that you can hear the difference.

    Enjoy.

    first test native iPhone microphone, have the desk fan running here to get some ambient background noise.

    second test level your microphone coming straight into the lightning jack already I can tell this is a lot hotter.

    We’re peaking a fair amount on the video.

    Third test the V moto boom microphone, which is this one here.

    Head worn microphone Fourth test the David Clarke bluetooth headset using the boom microphone on this this is a Bluetooth microphone.

    Next test to the Bose QC 20 IQZ 25 This is the Bluetooth microphone built into the headset itself.

    Next is the chemo funnel wireless 2.4 gigahertz microphone This is a technically a wireless microphone but there is a dongle that goes into the phone via the lightning jack.

    And finally the aftershocks arrow facts.

    This is the Bluetooth bone conductance microphone that I’m will be interested to see how it turns out to see if it’s just using the standard air microphone or if it is using the the bone conduction as a form of microphone as well.

    Of course, how could I forget Apple’s own air pods see how these sound recording video as well.

    So got a wide variety of different types of microphones to test you So they have it eight different microphones.

    Now I would say for the type of video creation that I do, which is mostly talking head, the lava Lee are sounded pretty good.

    The chemo fun.

    had one mic sounded really good.

    The boom the Wii motor boom mic also sounded really good.

    So if I was making videos just in this kind of environment where wired or wireless didn’t matter, I definitely would use one of those three.

    If I’m pure wireless, and I want to remain pure wireless.

    The bows were not bad.

    And the air pods actually surprisingly were not bad at all.

    They you can tell they’re a little more hollow sounding.

    They don’t have quite as much depth, but overall, not terrible.

    And the aftershocks were a disappointment and the David Clarke’s the David Clarke’s really do sound like you’re in helicopter right? So if you are going for that very specific type of effect, these are the ones have you’re looking for high fidelity voice quality for like a webinar.

    Definitely not you really do sound like you’re almost phoning it in.

    So lots of different options there.

    In terms of costs, certainly the lava leaders the cheapest, you can get a halfway decent lovelier mic for like 11.

    Right? The chemo funds around50 which are okay.

    The air pods, you know hundred 70 that was going to run you the Wii motor boom Micah sound30 now I think so that’s, that’s quite affordable.

    And then the Bose head count everything about was cost an arm and a leg so.

    So based on what you’ve heard, based on what you saw, in terms of portability in terms of size in terms of stuff you want to lug around, what are you going to choose for the type of content you’re creating, I would say if you are really concerned about size, and you want the lightest possible work, the air pods didn’t sound horrible, right? They would need some post production to to be things up if you’re okay, with a little bit more cargo, the lovely I think it’s probably your your next best choice.

    It is wired though, so it’s not truly wireless.

    But again, if you’re just carrying around a phone on, on a stick or whatever, it should be fine.

    So enjoy this.

    Hopefully it was useful to you and informs your microphone purchases going forward.

    Take care and talk to you soon.

    Machine-Generated Transcript

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    In today’s episode, Amy asks, I saw this cool setup you’re using at the marketingprofs conference, would you mind sharing what hardware and software used I’m in the event space and tried to do more independent recordings like this

    great question. So Amy was referring to the fact that the, unless explicitly forbidden, I tend to record all of my keynote talks. Because a, I want to know how I sound and I said anything that was useful and be because a lot of cases I want to be able to produce the content and distribute it very, very quickly. Typically, when I do my own video, I will have the video edited and available within 24 hours of the event. So one of those things where

    it’s, it’s helpful to the attendees, they if they wanted to remember something, they couldn’t remember exactly what

    I said, Hey, here’s the video, here’s the audio etc.

    So let me describe some of the equipment that I used do this and some of the software and there’s a separate

    video that

    I have. It’s up on the trust insights YouTube channel, how I do the actual editing process, but I can describe some of it here. So first, let’s talk about the hardware. This little contraption here is a three part tripod and there’s two

    pieces the clamp is by square jellyfish. By the way, all this all the technology pieces are links in the blog post. So check the show notes to get to the actual URLs for all these pieces. They are affiliate links on Amazon. So full disclosure. So there’s the the the smartphone tripod mount. I love this out. Because it rotates

    it can really do portrait or or landscape mode for your phone. I don’t know why anyone would ever record themselves in portrait. But if you want to do video chat or something that’s useful, and it’s just got the expandable clamp so it can take up to a gigantic phone.

    This is a mount by ultra pod. This is the ultra pod to I used to use the grill apologize amounts, but the legs keep breaking on me. So this one’s handy. x is equal to go tabletop or I’ll fold up and I can

    take the Velcro and just sort of strap it

    to a pole and then adjust the head so that I can it’s it’s the correct orientation. I do this a lot with lighting polls. So if there’s an event that has lighting of some kind of strapped to the pole, you know, clamp it down and it’s ready to go. And of course the the smartphone goes in here now the video and the audio are separate.

    So I don’t try and do the audio on the same thing. What I do next

    is

    I will take I have a task cam Dr. 05 which is a very nice audio quarter that the mic goes right in the top here. And then I have the the team of fun the head

    worn headset which is a wireless thing so there’s a piece down here this is piece over here has about a range of 10 ish feet I think give or take and so it’s it’s not bad for for that what I do with that is very straightforward. I take the

    put the chemo fun on the podium usually, or the lectern or whatever is nearby. And then I will record the audio from that on on this got

    here. And this gives me your mp3 or WAV format. Typically for voice, you can restore an mp3 format. I know that if you are doing something high fidelity, like sing or music, you definitely want to record and wave but for voice, it’s fine.

    Um, one of the thing I’ll do is I’ll take a power pack, you know, this little,

    these little ribbon thing is that people give away a conference and trade shows these are fun because

    I stick on the back of the power pack of this. Typically I will put

    on the band of the tripod, right. So I’ll weave this this through here. And this way, I can plug in my power cable right to the smartphone, the phone mount, and that way I don’t have to worry the phone running out of battery wallets do recordings. One critical thing at least for iPhones, I don’t know about Android,

    make sure it’s an airplane mode. When you’re recording video,

    I have had

    unfortunate cases in the past where

    I’ve been recording video, and it went of call came in or something. And that interrupts the app and the video app. I don’t know why Apple doesn’t fix that. But so be it. So those are the major hardware pieces. Remember, audio and video are separate. The audio is at the podium, the video is typically in the back of the room, I’ll try to put as far back as I can, because

    you want to capture the audience if you can, at least as a speaker. So you can see their reactions like everyone’s like, on their phone, playing games, whatever. Okay, clearly no one’s paying attention to this part need to rewrite that part of the speech.

    Now the editing process the audio comes in from the task cam

    take that into Audacity. I like the audacity editor. Because frankly, it’s free.

    And it’s really really good. It now if you are already paying, especially if you’re at an institution, an organization if you’re already paying for Adobe Creative Cloud, then use although we audition to do the audio editing because you’re paying for it will use it.

    The things to do there are trim it normalize that because you can get some

    interesting effects. And you want to do dynamic compression on the audio. So like right now what we’re doing

    here because I’m speaking in a relatively narrow band of audio, meaning I’m not yelling, and I’m not whispering I can just do your typical leveling, but you want to do normalization if you’re doing public speaking, because as a public speaker, some the old have a lot more variants and how loud you are. And so you want to normalize that then

    make a WAV file of that take that take put it into campaign Asia, put your video into camp Asia, and then you line up the audio in the video together so that they are in sync but not a header behind each other. This gives you one additional benefit at least as a speaker and it gives you the house

    and by that I mean house noise because the phones in the back of the room. So the phone is going to pick up some the reverb right. So you want to to do a little ducking incantation to reduce that but for things like q amp a from the audience and especially as a speaker and an events manager if you’re in the if you’re producing audio for events you want applause right you want you want the sounds of the event that people Leo cheering or or laughing along lines and

    the head one Mike does a really

    good job of getting rid of the surrounding noise. So you want to bring some of that back in when you

    when you are doing the editing to. And that’s what the phones audio is going to give you gives you the ability to bring in out the house sounds as you need them.

    And then I’ll take that WAV file typically. And also I’ll take the stage at video once it’s done. And then I’ll feed it to a free tool called f f. MPEG. It is a command line tool. It is a technical tool it is not there is no user interface you have to type commands into the command line but is a very, very powerful tool for converting one type of media to another. And what I will do is I’ll take the final video file and I will have that turned into an mp3 that then becomes either a podcast episode or I will send it to an app called otter Ott er otter.ai that will do machine learning transcription of the audio so for the event I’ll take the transcript I’ll take the audio and turn into a transcript and that way

    you can see the video you can download the audio if you want to listen to it the car you can get the slides as a PDF but you can also get the transcript of the talk as a PDF

    now

    if you if you are running an events company you will want to polish it up because

    it comes out very much as is for a speaker you can find get away with either depending on how much time you have and if you have a VA or not but I really like that because it gives everybody those your talks in the format that they’re most comfortable consuming they Some people like to listen Some people like to watch some people like to read so that’s sort of the process

    for turning a talk into lots of different media and for giving it to people in the form of that they want all this hardware probably after all said and done probably about $200 total

    except for the phone to pay whatever you pay for the phone

    this guy I think it’s like 25 bucks the headsets 50 this guy’s 72 I think there’s anything else

    that’s that’s about it contagious a couple hundred bucks I believe

    but you don’t need to use it you could use like I movie or Windows Movie Maker I personally wouldn’t but I like camp Asia because it can also do is like picture in picture and and diagrams. If some talks at the video isn’t great. I will like show the slides I’ll have the slides been picking a picture and picture whatever if I want to talk to be like really, really well professionally edited.

    Or if I can’t see the screen in the video I captured so that’s the process watch the other video
