Definitely consider me interested.
I think it would be a fantastic thing to have as a more AudioGuide-esque way of matching samples since more morphology could be retained (I guess theoretically), but then for general matching, distortion, analysis, etc… there would be plenty of uses for that.
Some PLA would also be great for downsampling complex filters (ala the spectral compensation stuff, which presently loses lots of resolution going from 40melbands down to 8 static cross~ filters).
