I want to start recording my acoustic songs to watch and look for mistakes and other issues.

Can anyone recommend a good webcam that does a decent job with both audio and video?

if you're just checking for mistakes and such, any webcam with a microphone will suffice, it all depends whether you're computer/laptop is able to record without lagging on the video, also i'va had a problem with my mac webcam it tends to speed up the audio to a ridiculous speed so if doesn't match the audio, but this is a quick fix, so just go into you're local computer or electronics place and ask for a cheap to mid priced webcam with a mic, that will be absolutely fine for what you want
