In my case I recorded the entire night, an approach which you should do as well, and then strip silent parts from the recording in an extra step. This way you will not lose material in case your filter is not configured optimally. I must say that I was more in need of a snooring detector than any other detectors though. ;) SoX has two effects, silence and vad (voice activity detector) which can possibly anaylze your recording. One would have to put this inside a script that chops off segments of your recording, and then repeats the same action with the remainder. A research using ixquick gave the following as well: https://github.com/amsehili/auditok The aubio toolkit on Debian offers two binaries: aubioquiet - a command line tool to extracts quiet and loud regions from a file and aubiocut - a command line tool to slice sound files at onset or beat timestamps which sound promising as well. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
