but how to fill a table with a sound with more than 4000000 samples ?
what is the problem with that?
also I need high fidelity playback at nominal speed.
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.

Hi,
I'm looking for the best practice to scratch (change playback speed quickly) large sound file.
I've already tried :
- table and tabread4~ but table length is too limited
- readsf~ : can't change playback speed easily (I didn't try resampling
with block~ yet)
- august/readanysf~ : seems pretty great but can't play backward, it also
has a great feature : the return
- moonlib/sfread2~ : works with both positive and negative speed but only
with 16bit audio file and quite buggy (strange output when it can't find file)
- moonlib/readsfv~ : works only with positive speed
Does someone know how to play large sound file with playback speed control (positive and negative) ?
Thanks
Antoine
