what is the problem with that?

Miller's varispeed example does achieve that. it uses the right inlet of [tabread4~] to prevent loss of precision.

Thanks for the hint, 
 
but how to fill a table with a sound with more than 4000000 samples ?
is there a direct-from-disk solution for that ?
also I need high fidelity playback at nominal speed.
 
Thanks 
 
Antoine

Which one? 
 It's supposed to be possible with tabread4~, by using the onset inlet.
There's an example in one of the help files. I looked at it a year ago and
it was incomprehensible. YMMV.

If you figure it out, please post a simple example patch. This is my
greatest joy-killer in Pd, because I really want to work with audio files
which may be 1-2 hrs long.
