im having trouble getting a good recording - so what i have at my disposal: > A pretty powerful laptop >Power amplifier >12 channel mixer >8 wireless mics >$100-$600 budget (or up to 1k, if the difference is WELL worth it) my method so far: theres a grey little wire that i can connect to the side of my laptop. (like when connecting headphones, but the port thingy beside it) and that records everything anyone says on any mic that i turn on via mixer. on my laptop there is a FREE recording tool which i use... called "sound recorder" well. my problem is, when two or more people start singing into the mics. oh the nastyness most uglyest metalic weird noise comes out when i save it. i know ill probably need to put in a little more cash, but whats the most important things i need to at the very least record everyone singing clearly?
