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.

    The project is to invert the MFSK-64 protocol, its used to send text over Ham radio (in this case i generate the tones with Fldigi). I want to make a fusion between data and music. But the tones itself would be rather annoying to listen to, so my idea was to send “sound holes” where the tones would be, and then to decode holes instead of tones. This would allow me to use any music i want, and just encode the data into the holes, a song missing a few frequency’s here and there is still listnable.

      Very neat! I dig it, that’s a fun project.

      I’ve reinstalled Reaper, I gotta basically completely re-learn it before I can do much. I used Ableton and Reason mostly, again, like 15+ years ago. But it’s definitely doable with the right setup of notch filters and gates

        I think it could be done, just a matter of time and tools.

        I have tryed this tool here https://nsspot.herokuapp.com/imagetoaudio/ when take a picture of the waterfall display, then invert it with krita and send it thru the converter a second time. Problem is that is rather crude, it makes the pixels in wich i can take the screenshot the bottle neck and the results are not fine enough for musik.

        Have fun with reaper, i am a total audio noob so i have been playing with it for a few days but still discover new stuff constantly :D
