In a failed attempt to create an effect that would mimic the weird reverb in Pavement’s The Hexx, I made this effect, which I think sounds pretty cool and is worth sharing. It is some kind of echo that constantly detunes the sound downwards. It sounds really nice to me, although it obviously won’t fit in just any song…
I won’t go into the details of how works. Just like some other pitchshifting effetcs, it is based on the Doppler effect, and uses delay lines with varying lengths (read Miller Puckette’s book for more info on delays).
Please note the use of audio send and receive objects ([send~], [receive~]), that make the patch a little cleaner.

And here’s a sound sample :
