I use a program which plays regions of various .wav files. Its

SoX can be used in simple pipeline operations by using the special filename
`-' which, if used as an input filename, will cause SoX will read audio data
from `standard input' (stdin)
Can't quite do it though. aplay gets -f FLOAT_LE -c 2 -r 48000 I've tried:
| sox -t raw -r 48k -c 2 -L -e float - dump-SOX-test.wav
sox FAIL formats: bad input format for `-': data encoding or sample size was not specified
| sox -t wavpcm -r 48k -c 2 -L -e float - dump-SOX-test.wav
sox FAIL formats: can't open input `-': WAVE: RIFF header not found
I'm guessing though really.
Have you tried directly with the trim and/or splice commands SoX
provides to extract the audio regions of the original file?
