20-Second Clarinet Solo compressed to <1k

I think that this is probably the sonic equivalent of vector graphics. "In order to get this done, they created a model of the clarinet itself -- essentially replicating each aspect of the sound rather than creating thousands of digital samples from a performance of it. The resulting file occupies less than a kilobyte despite including all of the audio materials. By comparison, the same clarinet sample would occupy 32KB as a MIDI file."
