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.

for direct to disk, nominal speed, use readsf~

Thanks

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.
