?Download my Sounding Your Best as a Podcast Guest worksheet here!?After fifteen years in the voiceover industry, almost three years of hosting the Audio Branding podcast where I talk about the power of sound, and having been a guest on a number of podcasts myself, I've learned a thing or two about creating quality audio. I hope some of the lessons I've learned can help you find just the right sound for your own setup. I'm going to talk mostly about being a guest on podcasts, but this will give you some tips on how to improve your sound if you're a host as well.  Either can be a challenge, between all the different equipment each side might have, how far apart they might actually be, and making everything line up so that it still sounds seamless.  But here are a few tips I've learned about how to create the best sound impression – specifically as a podcast guest.The first step, and probably the most important, is to have a separate microphone. I’ll talk more about choosing the right mic for your needs in just a bit, but for now, the important thing is to just make sure that it’s separate from your computer or phone. It doesn’t have to be the most expensive mic out there: just having a dedicated device can make a world of difference in the sound quality.Just as a dedicated microphone makes a huge difference in the outgoing sound quality, headphones make the same difference when it comes to the incoming sounds and keeping the two separate. You don't need expensive headphones either, and they can be any style you like: in the ear, over the ear, either way is fine. But there's one tip I've learned through hard experience that might not be obvious, and that's to make sure that "echo cancellation" is turned off.Echo cancellation is a feature you'll find on remote recording services like Squadcast, Riverside.fm, and Zencastr. It works by cutting off your microphone when someone else is speaking so that background sounds, the sort that you'd have if you're listening through speakers rather than headphones, don't carry through your mic. That isn't necessary if you're in a quiet room and wearing headphones, and turning echo cancellation off means that your voice comes through quicker, cleaner, and much more smoothly.Speaking of keeping things quiet, the recording environment can make all the difference. Is there a lot of traffic or noise outside? Closing the door and moving away from the windows can make a bigger difference than you might think in keeping those background noises out of the recording. Is your phone turned off? Are any white noise sources like fans also turned off? We’re often surrounded by ambient sounds that we hardly notice, and it’s worth taking a moment to listen carefully and make sure the room really is silent.And what about the room itself? A lower ceiling is always better when recording, and you'll want to avoid glass, hardwood, or being in a large room that might echo. If you aren't on camera, a closet filled with clothes can make for a surprisingly simple and effective recording space: the small space, low ceiling, and layers of fabric all help absorb the room noise. If you'll be on camera, a smaller room with less hard surfaces, with rugs or carpet on the floor and a fabric backdrop like a wall curtain or blanket over a wardrobe, can help the sound quality while also making a good impression – not to mention hiding an unmade bed or laundry you haven't put away.As for choosing the right microphone, there are a few things you’ll want to consider. First, do you want to use a condenser mic or a dynamic mic? A condenser mic can be the perfect choice for a quiet, sound-treated room, and it offers a more nuanced sound for recording the human voice. But if you don’t have the option of creating such a dedicated recording...
