A: Gaussian noise

B: Signal Tones

C: Gaussian noise with ‘tone holes’

How can i create holes in gaussian noise?

I have a track with gaussian noise and a track with a tone signal, i want to take the 'negative" of the tone track. Picture C describes how i imagine it would look.

    My first instinct is phase inversion. I feel like we can do this with sidechaining again though.

    A couple filters to isolate the frequencies you want to remove, and then a gate? Idk I might have to fiddle around in Reaper later and see what I can come up with. It’s been like 15-20 years since I spent much time in front of a DAW. Imma think on this.

      I am also trying with Reaper right now, sadly i didnt have much luck with phase inversion.

      Maybe i can track the tones somehow and then shift a notch compressor or something like that over the noise. So if for example there is a 300hz tone in track B, it will move the notch compressor to 300hz in track A. No idea how to track individual tones sady

        You could maybe EQ/filter down to the tone frequencies and then pass it to a gate… a notch filter (or a couple) should work.
