Episode 111: Audio Recording Tips

Summary

Nick and Kai walk through the gear, room treatment, technique, and video setup needed to record clean podcast audio. There’s a running disagreement: Kai thinks content beats audio quality and encourages shipping early with whatever you have; Nick thinks podcasts live or die on sound quality in a way that a text mailing list simply does not. They land on a practical middle ground around a $300–$500 rig that gets you most of the way there.

Highlights

  • Nick’s position: podcast audio quality is non-negotiable in a way that bad mailing list typography is not. Kai’s position: ship the thing first, upgrade later, Apple headphones are fine for early episodes.
  • Kai’s current rig, Focusrite Scarlett Solo interface, Shure Beta 87A supercardioid mic, MXL BCD boom stand, cost under $300 total. Nick puts the ‘nice option’ at around $500. eBay and Craigslist are good sources for used gear, though without Amazon’s return protection.
  • A supercardioid mic has an extremely narrow pickup pattern. Nick demonstrates live by turning his head to the side mid-episode: noticeably quieter even at the same distance. This is what keeps a dog snarfing off the recording.
  • Microphone technique matters as much as the mic itself. Keep your lips just touching the windscreen, stay directly in front of it, and don’t move. Nick describes the alternative: volume drops in and out as you gesture, and it sounds like garbage.
  • For room treatment, start by covering the wall directly in front of you with foam tiles, that’s where sound bounces back into the mic. Add side walls, then ceiling if reverb persists. Bass traps go in room corners for low-frequency problems; Nick notes they’re expensive and awkward but necessary in rooms with a lot of bass.
  • Video framing: camera at forehead height, front-lit with either a window or an LED panel on a tripod. Nick uses iGlasses to control focus and white balance on his built-in iMac camera; Kai uses Webcam Settings for his external Logitech 1080p webcam for the same reason.
  • What’s behind you on video gets noticed. Nick cites a prospective client call where the person was clearly in his grandmother’s living room, undecorated, as a real example of a bad look.

Nick

I think I sound okay. Do I sound okay? You sound good. Five by five. Sound good? Five out of five. Except that one time I had a viral infection and people ignored it. Yeah. Except my mom. But uh no, I I have gear, it’s in front of me. It’s always impressive when I get on video calls and they they’re looking at a boom stand and all this all this Falderall, big pair of headphones. But overall, I I bought barely enough gear that I’m going to sound good. And I just looked at some experts and I went on the website um it’s for jungle enthusiasts. It’s called Amazon dot com and uh bought a bunch of stuff. And that’s about it. I then I moved. I bought a house and my office is about it has like ten foot ceilings. which is very tall ceilings. So I bought some foam tiles to put in the room. And that’s it. End of things that I have done for this podcast. I deliberately took the room that was closer to the back of the house so you don’t hear street noise. Shut the door so you don’t hear my refrigerator. Hired editors so I don’t sound like a charlatan. I don’t know what else to say as far as what the gear is, right? Like you have to get a microphone that has a narrow pickup pattern. Microphones are either good for like a room, like Recording an orchestra, like many things at once coming from many different point sources? Or they have very narrow pickup patterns, which are good for vocals, and you would see it like a rock show or something like that, like somebody singing directly into the microphone. And I have a microphone that’s like an extreme version of one of those. So when you get to like the side of the microphone, I’m going to turn my head to the side and you’re going to hear me speaking like this, right? Hopefully. And I again, I’m just as close to the microphone. But hopefully, you hear that I’m quite a bit quieter. So that’s kind of like the natural pickup of it. So if my dog comes in and starts, you know, snarfing his butt during the middle of my podcast. You mercifully do not have to hear that, even though I do.

Kai

One of the things that always has fascinated me with Audio, and this is something that we probably do not see eye to eye on. Is I don’t think that the audio quality needs to be at 100%. I think the content is more important than the audio quality. And I’m an evangelist for just shipping it. Start a podcast. Use your Apple headphones. Yeah, audio might be like. A C minus for the first 10 or 20 episodes before you upgrade to, say, a oh, what is it, a blue snowball or another good starter mic. But that’s fine. Like the important thing in my mind is the content. You’re saying interesting things. You’re shipping it. Before. There’s a focus on gear. I like there being a focus on content in a podcast or a series.

Nick

Yeah, I so I tried doing a podcast like God a long time ago, and I thought it would be punk to do like something lo-fi by going on getting like a crappy mic USB microphone on my crappy laptop in a crappy space and just having a conversation. And you’ll find that like guests will be willing and that it’ll be like a nice vibe. And then you turn off the podcast and it’s a feral disaster. And I realize the people they care a lot about audio quality. They seem to like a podcast really lives or dies based on the audio quality. Contrast with my mailing list. It’s in Georgia. A crappy font that sucks, like, and no one seems to care. The typography is horrible because it has to be cross-device, and no one seems to care. But I don’t think that’s the case for podcasting. I think you actually have to come correct. And it’s not hard. It just takes a little bit of money to actually buy the gear. and it’s a one time thing, and there’s probably dozens of failed podcasters on eBay putting up their gear so you can get it on the cheap.

Kai

Oh, there are. There are. No, eBay, eBay and Christlist I found in larger towns are great deals for, obviously, used equipment. like podcast rigs or anything like that, you could definitely save some bucks. But you don’t have the protection of like Amazon’s return policy or eBay backing you if there’s an issue with it. You only have the thing that doesn’t work anymore. I recently upgraded my rig, and I think it’s pretty similar and nearly identical to yours right now. I’m using the Focus Bright Scarlet Solio Solo audio interface with the Sure Beta 87A Super Cardio Eye. And what did I upgrade my stand to? I upgraded to the MXL Mics. MXL B C D stand. And I’ll drop links into show notes for all of these. But altogether, upgrading to this cost me under 300 bucks, I think.

Nick

Yeah, you want, just broadly, a USB preamp for a microphone and an XLR supercardioid microphone. That costs around $100 to $200. And the interface doesn’t really quite matter. You just need to make sure it’s not going to have any hum. And that’s it. I have some cables. I have a boom stand so that I can talk and be on a a camera all day. This is my fifth meeting of the day, right? It’s the last thing I’m doing today. And that’s it. And I have a pair of nice headphones, but honestly, they’re the same pair of headphones I used to DJ with in college. Like, they’re just a crappy pair of $50 Sony headphones. They’re studio monitors. And they’re closed ears. So I uh Don’t have to hear like background noise or anything like that. So there’s nothing but me and the microphone in front of me, and I’m just going. And it works out really, really well. I don’t think you have to overthink this. Like, again, the all in for this, the nice option is about five hundo. If you’re a consultant, that’s a round off error. If you want to start, get a crappy USB microphone off of eBay. Everyone seems to like the blue snowball, but it’s very omnidirectional, so you need to be very careful about your room noise. And they always seem to mount it so it’s low on the table. So let’s talk about why good microphone technique is important when I am talking, my lips are just barely touching the windscreen on my microphone. I’m directly in front of it, and that way I’m able to have a lower volume on the microphone, so that picks up less background noise. The thing that you need to be sweating in that situation is making sure that your face does not move away from the microphone. Because when you’re talking, it’s going to sound like I’m about to go. I’m going to move slightly away from the microphone. I’m going to, you know, move around, do my normal gesticulation. I’m going to have my normal thing. It sounds like garbage, right? I come in and out, right? So, you have to hold your head still and make sure that you’re focusing on the sweet spot of the microphone that’s directly in front of you. And you end up sounding a lot better. I hope that I sound better than I just did.

Kai

I could barely notice a difference in all honesty.

Nick

Okay. Well, that’s fine. I’m my biggest critic and I notice a difference. And if you have on really nice headphones or in-ear headphones or something like that, or you’re our podcast editor, you almost certainly notice a difference. And I think that matters as far as turning out a good product. And honestly, if it’s a matter of like don’t move your head for thirty minutes, we’ve got this That’s fine. This is not a hard ask. It’s a weird thing that does not come naturally to people, but like neither does running a consultancy, and you’ve been doing a lot of unnatural things for a minute. So hop to

Kai

Fair. Fair. It’s a small buy-in to get the equipment you need to produce good audio, and then you really could just freeze there. Like it doesn’t need to be an arms race. I can’t see myself honestly upgrading past this unless I have a need to have a mobile rig like you bought last year. That honestly is the only real circumstance I could see upgrading here. I want to, this diverges from audio recording a bit, but. I really want to upgrade the video sometime soon. Just get a DSLR to use at the desk to record video and be set with that. Yeah. Yeah.

Nick

Yeah, I mean, I could easily blow another five or six grand on just a microphone and a preamp for this. I could blow probably half a grand on cables that are materially identical to these cables, but they make me feel okay. And if you want to stroke your ego, go for it. But like, it becomes very much a game of inches after about $500. And even then, like you’re doing really, really well for yourself, and you’re going to sound like a serious put-together consultant. If you’re recording video, there are two things that have helped me out. And this is sort of like if you’re doing screencasts, but it’s worth mentioning. I’m backlit in this room. Like my ceiling light is behind me. the outdoor windows behind me. So I need to be frontlit. And if you don’t have the luxury of having a window directly in front of your face, you’re going to need an LED panel. You put this on a tripod, you attach it to a switch, you turn it on when you’re recording, you turn it off when you’re being a computer hacker, end of thing. The second thing that I have, I have a twenty seven inch iMac, and I found that the white balance and focus on my default camera settings It does not look good. And so I tried thinking, like, well, do I get like a DSLR and just aim it at my face? And I know some people do that. That seems crazy to me. And I found an app called eyeglasses underscore or lowercase i, then capital G. all one word, like it’s an iPod. That allows you it gives you all of the levers and settings that you need on your camera. Focus and white balance and zoom and stuff like that, so people can see my face a little bit closer up. It allows me to set the monitor a little bit further back, which is good for my eyesight. That’s a tiny gear thing that I found to be really, really helpful. Overall, you want the camera to be about forehead height. If it’s any lower, it’s going to look like the person is looking up at like a god of some kind, and you’re not that. And if you’re too high up, it’s just gonna it’s gonna feel distant and weird. So you need to make sure that it’s like you’re having an actual conversation. And I think that’s it for video. I don’t care about Anything beyond that?

Kai

No, I’m trying to think what I’d add here. The light is great. I’m adding links to what we both used to the show notes. So with eyeglasses, that’s for the native I can’t even remember what Apple calls it, but the native I think they call it eyesight. The native eyesight. I use webcam settings. I use an app called Webcam Settings to help me have that same level of control, but I use a Logitech external webcam that records in HD 1080p. And I found the webcam settings app to be very, very nice for the exact same reasons you pointed out. Let’s adjust the color balance. Let’s be able to zoom in. Let’s have a little more control rather than just what I could do out of the box or in the program I’m recording in. So that’s an application that I also recommend for folks. I tried eyeglasses, but it seemed to not be compatible with an external camera. only with a built-in camera. So webcam settings is where I ended up.

Nick

All right. Fair enough. Yeah. Computers. What other audio recording tips? Shut the door. Disconnect your doorbell if you remember. I have like one of them portable doorbells, and unless I’m like expecting a FedEx package, God help us. I usually disconnect the doorbell. Make sure that your computer’s fan is far away from your microphone and hopefully pointed in the opposite direction. If you want a big level up move, buy some foam tiles and treat your room.

Kai

Here’s one thing I’ve always wondered: how are you supposed to identify where you’re supposed to put those foam tiles in a room?

Nick

It is very much trial and error, actually. It’s weird. Basically, you start by well, I’m talking at the wall, right? So if I’m talking at the wall, it’s likely that sound waves are going to bounce back off the wall and into my microphone. So that’s the first place you should be going, is the wall that’s directly in front of you. So right now I’m looking at a wall full of foam tiles. Another thing, if there are um this matters if you have a beautiful and inspiring baritone like I do. There are What are called base traps that you put in the corners of a room. And there’s all eight corners, like they’re the vertices of a cube you have to think about. and they’re fucking expensive and horrible, and um but they suck up all the bass frequencies. The goal is to make it kind of as flat as possible. So it just sounds like a normal Room. Well, it sounds like a voice that’s next to you, and you don’t hear the rest of the room. You don’t hear reverb. You want to deaden as much reverb as humanly possible. So, what I would recommend is Cover the wall in front of you with foam tiles. If that doesn’t sufficiently deaden the reverb, cover the walls next to you with foam tiles and the wall behind you. If that doesn’t deaden the reverb, congratulations, you’re going to sistine chapel this and go to the ceiling. If you’re dealing with a lot of bass issues, like a lot of and you have to listen very carefully on nice studio monitors. Then you install base traps in your room, which are basically like foam tiles that go in the corners and cost five times as much. And you can shuffle things around at will. You want to make sure that those tiles are pointing in different directions. So like it’s a checkerboard, one is horizontal, one vertical, so that it’s like Vanta black. It takes in the sound and the sound bounces around inside of these little fins. And it doesn’t give it a chance to escape. I think that’s the answer. I’m sure some audio engineer wants to murder me for how ham-fisted of an answer that was, but I don’t care.

Kai

But for somebody out there who’s listening to this and saying, Hey, I want to record audio, I want to start a podcast, I want to create a training product, I want to do webinars, anything that uses audio as part of it. I think we’ve outlined the necessary gear you need to get started. And honestly, my upgrading to the gear that we listened to the show notes here was something that just happened in the last two months, three months. And Yeah, there definitely are places you could start earlier than what we’ve outlined here, but this is a great package to level up with and just maintain and know that you’re able to produce good sounding audio consistently.

Nick

One last thing I’m going to say about video. What is behind you matters. People will comment on it. People will judge you on it. If you have a wall of acoustic tiles behind you, that actually kind of looks badass. If you have like a giant feral disaster behind you, that doesn’t look so badass. I had a client call, or a prospective client call, I never hired them, but it was with somebody who was very obviously in his grandmother’s living room. He did not decorate this room. It was not a good look. Make sure that you look good. Make sure that you’re in a room that can’t be judged harshly. That’s it. And then go forth and podcast and don’t overthink it and don’t spend $6,000 even if you’re busy and important because that’s just sad.
