In μAcousmatix battles, you mayn't use samples in ways where said samples are readily identifiable as their acoustic or electronic source. Instead, you must create new and novel textures!

Usually, though not exclusively, this entails samples being chopped to <100ms in length, and perhaps even shorter for percussive sources. If I hear a single bona fide snare in your submission, I'm going to be unhappy, so get hacking!
