Thank you very much! I have found a solution before I got your answer, but your solution seems to be a lot better. I fell kinda stupid, actually. I created a big sound file where all tracks were all 1 and the tracks that I wanted to silence all 0, then used multiply, them trimmed to the size of each original sound file. I'll do some more work with the same files, so I'll test this "remix" effect. On 03/27/2016 04:58 PM, Måns Rullgård wrote: > Eduardo Mezêncio <eduardomezencio@xxxxxxxxxxxxx> writes: > >> Hi!
