Sidechain audio compression in FCP?
I was wondering if there is a way to do sidechain audio compression in FCP?
I currently do this via a VST plug-in in EDIUS 4 or Vegas 7, making the aux input one track or clip, and the source to be compressed another track or clip.
I’m not sure if there is a VST to AU conversion possible for this type of plug-in, of if there is a native AU plug-in that does this?
What I use it for is for commentary tracks on DVDs. I do a lot of performing arts videos, and I have a director’s commentary track. For this, I need a sidechain compressor that takes the director’s audio as the aux key for the audio compressor on the show audio track, resulting in the show audio being compressed when he talks and released when he doesn’t.
Is there a way to do this in FCP via plug-ins or natively? My local Apple Store didn’t have an answer for this one. I’ve only found one VST plug-in that can do it, it’s called SideKick.
Thanks for any info.

What you describe is an auto ducker. The directors com dips the rest of the audio if I understand your description. No plugin within FCP can do that. Also VST doesn’t work in FCP.
I suggest you either do your audio track with other software or you could automate a mix in FCP, dipping the audio during narration using the mix tool.
If you have FCP studio, you can check if Soundtrack Pro has and auto duck or sidechain compressor plugin.

FWIW feature hollywood films on DVD don’t even do this. They just drop the audio nearly out and leave it there. I’ve never seen one do the auto duck thing. But then, on features they usually talk 95% of the time on the comment track.
