[PD] Good Time Stretching patches/advice?

[Jaime Oliver]

you can control the reading position, not just make automatic playback. Try different window sizes, with and without phase locking to see if you find something you are looking for. tHere are other phase vocoder algorithms out there, I think Alexandre porres made one for pd, maybe one of tom Erbe’s externals?

best,

I really need an infinite stretch though. If I go ahead and use [I07.phase.vocoder.pd], do I need to modify it so that it reverses its reading of the array once the end is reached, or so it cross-fades into a rewind, or is there a better solution?
