Sidechain frequency ducker?

morebutter · 28th October 2007

I would like to set up a frequency dependent sidechain compressor that ducks the main input with the frequency curve of the key input.

For example if the key input was a kick whose strongest frequencies were between 90-110hz, then the main compressor input , lets say a bass, would be compressed mainly in the 90-110hz area. So it would not compress the overall volume of the bass like a normal sidechain compressor but rather just the frequency curve of the key input.

I know I can set this up manually, tuning the frequencies of a multiband compressor according to the key input, however what I'm really after is a setup where it happens automatically according to what the key input frequency curve is.

Is there a multiband compressor plugin that does this automatically--compressing frequencies according to the key input's frequency content? If not then any idea how would I set this up?

This is a pretty cool VST plug. Not sure if it is frequency specific, but i suppose you could eq the keyed track to the appropriate freq.

Thanks I have a couple compressors that have sidechain, what I'm trying to figure out is if there's something out there that does it automatically. Tuning the compressed track will not work because the key input track will vary/modulate widely in frequency for the duration of the track.

To put it in other terms, I'm trying to find a way to make 'holes' in the compressed track for the key track to 'sit' in.
