Improved sidechaining.

[mromgwtf]

Hai

In normal sidechaining, modulator lowers the volume of the carrier signal. I had an idea about this kind of sidechain plugin, which works like this:

1. You specify the modulator signal
2. The plugin lowers not the volume of the carrier signal, but instead, it lowers the frequencies in carrier signal that come from modulator.
3. So for example, if modulator is a snare signal, which has frequencies around 200hz and high end, the plugin will only lower 200hz and high end of the carrier signal.

You can create this kind of sidechain simply in a EQ, but if you want to be more precise you need a better way to do that.

What do you think? I've been coding in C++/C# a lot, but I've never touched audio processing. If I get into stuff like FFT and VSTs, I may create this kind of plugin. It'll be hard tho, believe me or not.

Interesting. Probably useful if used subtly but I'm pretty sure it could introduce a lot of weird artifacts if you used it too much, the resonance would probably make the carrier signal sound really weird. You could probably use it creatively to get some really cool results though.

I think I'd still use normal EQ sidechaining if I want precision though.

If you mean dip per the frequency response of the trigger, a plugin already exists called spaceboy or something. It was discussed at KVR.

Here's some DSP shit.

Damnnn, thanks for the plugin, and damnnnn, thanks for the papers.

basically like a DeEsser
from what i understand in Fruity you can use peak controller to modulate anything more or less, including a band of an EQ, so there's that

[NinjaEdit]

No problem. I like this as well.

dom crazy!

This is neat, I'll check it out.

How I usually go about this exact thing (in Ableton) is to create a frequency splitter (Multiband Dynamics > Group >Show/Hide Chain List > Duplicate Multiband Dynamics to number of desired frequency bands > solo out designated frequencies) put a Compresser on desired frequency band and sidechain it.

It works great when I am trying to duck other track elements (bass group usually) in the 100/200Hz range for the kick and snare, not very noticeable either which is why I like it a lot.

Just sidechain the eq peak band on your desired frequency.

I do this all the time using FL Studio's Peak Controller. I do it a lot with melodies that occupy the same frequencies of a pad. I Just set the peak controller on the melody insert and then link it to the EQ band of the desired frequency range to create a small "valley" in the pad's frequencies.

This was brought up over on the Image-Line site and there was a guy working on a plugin to do exactly the same thing but more accurately. It's called the "Dynamic Frequency Responder". I have no idea if this thing was ever completed or released but here's a video of it.
