Sounds pretty neat! I wonder what kind of new instrument/effect plug-ins this will spawn. I haven't read the paper yet, but I'm curious about the 'vibrato' problem that the article mentions. I'm guessing the issue is analyzing a signal in a way that doesn't lose the vibrato when it encodes (ie: to sines, noise, transients), not a limitation of decoding a signal (ie: if it were possible to obtain perfect data)?
