Your Microphone (And Other Hardware)
The best thing you can do to improve the audio quality of your podcast is use a good microphone.
At only around $70, the ATR-2100 by Audio-Technica is by far the most flexible and best-value mic in podcasting. It plugs directly into a computer via USB or into a mixer via XLR, so it can grow with you as your podcast grows.
My primary podcasting microphone, also by Audio-Technica, is the BP40. I use a Mackie 1202VLZ4 mixer and a dbx 286s processor. You can hook everything up to your computer using a Focusrite 2i2 interface.
