[LAD] Time-Stretch

[Julien Claassen]

Hello Harry!
   I'm not too knowledgeable about this, but I know, that there are more basic 
choices, although I'm not sure for how much of this you will get stretching 
libraries. Tehre the approach of using FFT in the process, which might be 
quite CPU intensive, though I know, that there's good quality windows software 
out there, that uses it to great effect. I've heard some examples and "seen" 
it in action. then there's "simple" resampling. Which will get you the mickie 
mouse or daemon from hell effect, if it uses too much slowing down or speeding 
up. That is what you would get, if you do it with oldstyle tapes. Then there's 
something in between, quality wise. I think they repeat some samples or cut 
some out. I think soundtouch/soundstretch is using this approach. So 
especially if you need to keep in tune with something, I'd go for one of 
those. Resampling might be OK and probably the least CPU hungry, if you only 
need small changes in speed and if you are not going to use it for melodic 
instruments.
   That didn't help much, ey? but I hope I didn't tell you  something you 
already knew and thus could help you to subdivide your list into the different 
methods. So you might be able to discard a whole bunch of the libs you found.
   Kndly yours
           Julien
