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.
