A compressor with 2 inputs!

Postby Hexo » Thu Oct 03, 2019 9:58 pm

I'm thinking of a compressor that has a side chain input but responds to main signal at the same time. In other words it has 2 conditions in it's code like this:

IF the signal passes the threshold THEN IF the side chain signal passes it's own threshold THEN apply gain reduction.

Do you know any compressor that works in this pattern?
Any ideas?

Best,
Ahmad.

Why not just mix the two signals together and feed that into the sidechain? The compressor will then respond to the combined signal levels.

If that won't work - what's the use case that you're trying to achieve?

I dont know of any compressors that allow the normal input and an external side-chain input to be combined; it's usually just one or the other.

But the solution is simple: just mix together the input signal and the external side-chain input signal, and feed the combination to the side-chain input -- exactly as Desmond describes.

I Think you gave me the proper answer. I planned to reduce my vocals on kicks, but only if the vocal is loud itself.

thank you very much!

Well yeah! That should do it. You've always been there for us. Thanks a lot!

Hi again!
Although I've got my answer but I found something sweet here:

This simple Side-chain Mix knob can lead us to what we discussed earlier in Ableton!

Isn't this just a 'ducker'?

There is probably a pedal that will do it for under a ton.

DMG Compassion has a control to mix between the internal and external side chain.
