Can anyone give me a working example of the Sox compand command? The one in the Sox examples ( man soxexam ) does not work on my machine. Everything else works and it's great to have these examples or I'd never figure it out on my own. All I need is a working example of how to expand and how to compress using Sox and I'd be very pleased. This is what does not work: As root, using OSS play my.wav compand 0.3,1 -90,-90-70,-70,-60,-20,0,0 -5 0 0.2 The wav file is 16-bit, 2 channel, 44100 Hz The error message is: /usr/bin/play: line 205: 1576 Segmentation fault sox $volume $fopts $fopts2 "$filename" $arch_defines $device $effects duh? Anybody know how to fix this?
