Ah I probably should have mentioned. the friends don't speak through the game console. they usually use skype, but if there's any other way that'd be okayYou could probably get it done by running a record session of Audacity in the background while recording normally.
Then you'd grab both in-game sounds including your friend, and Audacity will cap yours.
You can get him to record his voice in audacity, then you record your voice in audacity, and then after the recording you get him to send his file to you.Ah I probably should have mentioned. the friends don't speak through the game console. they usually use skype, but if there's any other way that'd be okay
