Anthony Lemos of Audio Aperture Media successfully explains what mixers are for and what all those darn knobs and buttons are. Even if you're not into audio recording, I think you'll enjoy learning about mixers from Anthony. He doesn't use a lot of jargon, rather he breaks things down into simple terms that are easy to understand without a background in audio. I've never been able to figure out the difference between gain and volume, and Anthony's simple explanation finally clarified it for me.

Contact Anthony at @ethancaine. If you're interested in getting started in podcasting, he's very interested in bringing more diverse voices into podcasting and is willing to help you get started for free or very little money, or if you need assistance with a more advanced show he's also very interesting in helping.
