If you have read any of the podcasting book out there, you may have been confused by the choices in microphones. These books recommend a number of mics under a 100 dollars, but you can often find better sound for less.
A USB mic or mic/headset can cost around 30 to 40 dollars and provide a clean, noise free, professional sound. Most podcasting set ups that use a mixer/mic combination also uses a jack that plugs directly into the computer sound card. The sound card is typically located right next to the fan and the power source. This will cause a lot of interference.
I don’t regret spending 150 buck for a set up, but I wish I had known just how good a USB mic can sound before I did.
Don't forget the pop filter
You Need:
Pantyhose (knee high work best)
Wire hanger or wire
Tape
Instructions
Loop the wire leaving a 6 to 7 inch stem
Insert into the pantyhose and pull tight
Use tape to attach the pantyhose at the bottom of the loop
Trim off extra pantyhose
That’s it.
I agree with Daryl about thinking twice before buying an expensive condenser microphone. I did my first 10 or so shows with a USB dynamic microphone and it worked fine. To be honest with you, my sound quality actually got worse for a while I was trying to figure out the mic, mixer, and my room dynamics. I still think I pick up more room noise and echo then I did with my cheap mic. The advantage of a condenser mic is that you get a richer sound.
