[PD] time stretching with pd

[henrik wurster]

hi again folks,

many thanks for the help offered in my last request concerning the bonk object.
so maybe this time I will make a complete fool of myself, but is it possible to
time-strech .wav files with pd (meaning changing the length but not
the pitch of sample?
knowing that it works in applications like live, I feel that this
can`t be a simple operation;).
but maybe there are some abstractions already contained in pd dealing
with this issue ?
interested to hear your respondings...
with best regards,
- henrik
