WAV files have a bit of information that contains what the sampling rate is, the channels and the bits per sample: hydrogen,ttyp4,/home/johng,504$file /tmp/quarter.wav /tmp/quarter.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 8 bit, mono 22254 Hz so, if you want, you can use sox to convert the raw audio data into wav: sox -t cdr rawcddata.cdr somefile.wav -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."Received on Mon Sep 19 2005 - 07:55:48 UTC
