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)
