Default Reaper action that will lower the volume of a music track when voice audio comes in ?

I have a music bed of soft strings on one track.
I want the volume of this track to lower when my voice narration comes in.

Some radio stations use side-chaining.
But is there a Reaper action that will look through a voice audio track and produce volume envelopes on the music track ?

Side-chaining for me, comes in a little too late, I want to lower the volume 0.5 seconds before the voice starts, - the side-chaining comes into play at the point when it sense the voice about to speak.

Just increase the attack time of the sidechain compressor?

If you really need a faster attack, you could try the trick shown in this vid, basically a sidechain compressor fed by an identical track shifted 50ms earlier to make the compressor react faster.

Just sidechain ReaComp. It's got a pre-comp setting. Or maybe something more tailor made like some of these: https://sonic.supermaailma.net/plugins I think some of the JS versions of those are included in Reaper.

Aha, a copy of the audio track displaced to act as the sidechain. Genius !

great idea

and it would be very kewl to have something that would do it on the vol envelope...

however we do have automation items so that you could create one and copy it along the music track where your voice comes in and later leghten or shorten it as needed
