I was approached by a friend's band yesterday, and I'm going to be helping them with an album, for free, and they brought something up I hadn't thought of. They want to single out a kick drum hit on a commercial CD, and replace all the kick hits on thier tracks with it. Kinda like sound replacer, except I think they'll be doing it manually. At first I was thinking it would fall into the 'sample' category, being well under 1 second. But then realizing they would be doing it for the whole entire album, I began to wonder. I'm not worried about the technical aspect of doing this, it's an easy enough task from that point of view, given I/they can find a lone kick hit to use. It's the legal/ethical issue about it. Anyone have any experience or thoughts on something like this?
