Today's episode is a work in progress by Bill Sethares. From his description:

I've been working on mapping procedures to take the partials (overtones) from a sound (the source) and move them somewhere else (the destination).
The application is to create sounds (currently planning on using Kontakt [from Native Instruments]) that have spectra specially designed for particular tunings.

As I've been playing with the algorithms, I have been "trying them out" on complete mixes and have some interesting sounding results... for these two
pieces, the destination was set as all integer multiples of 65 Hz. So all of the "notes" are squished down to one big harmonic sound.
The source in this piece is Scott Joplin's Maple Leaf Rag. See if you can hear it through the rush of harmonic partials. Neat stuff.
