I am mixing for a 10hour long Audiobook.It consists of a vocal track and another for background music (mp3 file). I wanted to add Automatic level gain to the background music (mp3 file) when the transition takes place between 2 dialogues .As seen in the pic ,each dialogue consists of an audioclip and should be raised whenever a transition takes place from one vocal clip to another.

I was looking for a software DAW/ plugin to achieve this .I tried Cakewalk(sidechain expresssionenter image description here) and Audacity however this kind of effect is not possible .Please let know of any software which could achieve this automated effect.


  • It is possible using sidechain expression in Cakewalk, and similar in Ableton and Cubase.

You want to use a side-chain compressor with a slow attack and a fairly long release time. Drive the side-chain from the dialogue tracks. It may be necessary to use a compressor with look-ahead. Some delay might also be useful if the timing of the compressor action is a bit off.
