This is already being done to a large degree. Music information retrieval
systems can extract these kind of descriptors from sound files. People have
used sequences of descriptors extracted from one piece of music to
reassemble fragments of other pieces of music into new peices with the same
descriptor sequence but different sound sources. It's called audio mosaicing
and doesn't require an "linguistic" understanding of the materials...
