thanks for your answer, it's a very interesting example, indeed. but i'm
afraid i don't use PD... :-(  i'm just an old-fashioned csound guy...

yes, i know that with granular synthesis you can in theory stretch any sound
infinitely, but i never could make it sound clean and well. i'm trying with
the fog opcode, but i'm not satisfied with the results. the phase vocoding
approach sounds much better, with long analysis windows and high number of
superpositions i get passable results up to about 15 times.

i'll also try ardour, as suggested.

best,

lj
