Feature request: Use frequency shift to generate binaural beats

Opened this issue · 0 comments

It appears that binaural beats are generated through amplitude modulation, which is understandable if you want to peg the beats to a specific rate. However it is my understanding binaural beats are also generated by pure tones that are slightly off in frequency. I think it would be interesting to slightly shift the frequency of just the left audio track to generate a subtle beat effect.
