I am trying to use sox to increase the amplitude of audio stream in an mjpeg file, but before doing so, i am using sox's "stat" to determine the max. amplitude without clippping.
So my command line is: $ lav2wav file.eli | sox -t wav - -t wav /dev/null stat -v but both lav2wav and sox both use up negligible CPU in doing this job, and it takes far too long. lav2wav's CPU usage is about 2% and sox's CPU usage is about 4.5%. Seems like there is a bottleneck somewhere but where I am not sure. I have tried putting a "buffer" between them but no help. I am using mjpeg-tools version 1.6.1.90 and sox version 12.17.4. Any ideas? b.
