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.

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

yes, -resize flag and truncated output annoyed me, but making a table big enough at first and load without -resize flag works.

btw I do have a lots of high frequency artifacts. in the example, the playback speed is limited to 1000 sample/sec. But I need to play a 22 minutes long sound file with 44100 samples per second. So I set the play speed to 44100 and here the troubles begin....

ah, I see. you probably mean the "soundfiler_read: truncated to 4000000 elements" message in the Pd console. use the "-maxsize" flag to increase the maximum number of samples. on 64-bit Pd there's practically no limitation. with 32-bit you are limited to about 500 000 000 samples (~3 hours of mono audio)

for direct to disk, nominal speed, use readsf~
