It boils down to sth like this: tccat -t dvd -T 1,-1,1 -i \/dev\/scsi\/host8\/bus0\/target0\/lun0\/cd | tcextract -a 0 -x ac3 -t vob | tcdecode -x ac3 | tcscan -x pcm adjust the device to match your DVD-ROM. and replace the last step " | tcscan -x pcm" with " > ripped-audio.pcm" to write the audio into a file; or use " | tee ripped-audio.pcm | tcscan -x pcm" to write to a file and scan for peak values.. use sox or rezound or ... to convert the pcm into your favorite format! good luck, robin
