I should add that I'm a music producer myself and know very well how music is created. What I'm wondering about if it's feasible having an algorithm that searches for repeated instances of any sound (don't limit yourself to thinking MOD or samples) across a file and then marks these as "same" in order to save space. Any programmers who could tell me that?
