Thanks for reply.
I wanted to try by myself and I made last night a
quick hack for extreme time stretching by using FFTs.
I like the results very much.
Here are some demos (the links will work only for few
days):
Original sound is this:
http://zeus.integrasoft.ro/~nop/1stretch_paul_in1.ogg
Stretched (over 60x) is this:
http://zeus.integrasoft.ro/~nop/1stretch_paul_out1.ogg
Please tell me your opinion about the stretched sound.
The program is not complete (is just a quick hack
written in about one hour), but if you are interested,
I can put it somewhere on net (and make it usable and
improve the quality :) ).

>>Hi.
>>I found out a very interesting page and a webcast

>>And on this page ( http://www.notam02.no/9/tech.htm
)
>>I found that for this was used CLM and SND.
>>How can I do the same?

bit

>Halfly pseudo, it can look like this:
>(let* ((read0 (make-readin filename #:channel 0))
> (read1 (make-readin filename #:channel 1))
> (gr0 (make-granulate #:expansion 22.0
#:length >0.15 #:hop 0.03))
> (gr1 (make-granulate #:expansion 22.0
#:length >0.15 #:hop 0.03)))
> (do-X-number-of-times
> (output-to-file file-object (granulate gr0
(lambda >() (readin read0)))
> (granulate gr1
(lambda >() (readin read1))))))
>Very simple. You have to tune the length and hop
sizes >though, plus volume
>and stuff.
