you could try gyre for ideas:

a more recent version is in CVS.

it uses tabreadmix~ from the creb library to stretch the sample, but you 
could also use some variation on the B14.sampler.rockafella.pd example 
patch. even a phase vocoder of some type (although I prefer the dirty 
timestretch sound).

I think acid and live use some combination of techniques to stretch the 
material cleanly without making it sound "chunky" and still preserving 
the transients in the audio. that's a little beyond my grasp at this 
point, anyone have tips?
