Now with "find > place where gate works", I'd work wonders ;) -ge:open-threshold-%, close-thold-%,volume-mode Threshold gate. Initially gate is closed. It is opened when volume goes over 'othreshold' percent. After this, if volume drops below 'cthold' percent,gate is closed and won't be opened again. If 'value_mode' is 'rms', average RMS volume is used. Otherwise peak average is used. When closed, passing audio buffers are trucated to zero length. I could be wrong and I haven't used this gate myself, But .... I think you need to do something like this: 1)process original input file with -ge outputting to song1.wav If I understand "When closed, passing audio buffers are trucated to zero length." correctly, then nothing will be written to song1.wav after volume drops below the threshold. So, 2)get length of song1.wav and save it in a variable, like maybe position_variable. 3)process original input file with -ge outputting to song2.wav with -y:<position_variable> . -y sets the starting position. 4) get length of song2.wav and add to position_variable 5) return to 2), increment song<n>.wav and repeat untill finished. hope that helps, Eric Rz.
