So me and my friends have a sort of band setup, and we need to be able to record. what ive been doing at the moment is recording with a digital video camera, and then just extracting the sound file. However, the sound file that i get doesnt work with most editing programs, so then i have to convert it again, and it sounds pretty crappy by then. Is there any easier way to do this? Such as using a computer microphone and recording with windows sound recorder? And, would a Rock Band mic work for that?
yeah a rock band mic would work

already tried it
Fender MIA Strat w/EMG SA's
Fender Super 60
Boss RT-20 Rotary Sim
Ibanez AD-9 Analog Delay
EHX Big Muff

I'd recommend a Toneport, if you're on a low budget.
for fans of...

Motion City Soundtrack, Get Up Kids, Jimmy Eat World, Transit, Brand New, Dashboard Confessional, Early November, Fall Out Boy, Jawbreaker, Polar Bear Club, The Story So Far, the Wonder Years, Something Corporate.
yea a toneport interface or something similar for better audio recordings. you will have to track each instrument one at a time but it will be a nice little setup.

then export as WAV and import it to an NLE video program.
