You're doing the best animations on youtube. Binaruals are also great! Btw, do you know what is the best base frequency for isochronic tones for theta and gamma frequencies? Does base frequency matter or it can be random?
To be totally honest, I haven't experienced isochronic tones for any longer than 30 seconds ... I find them really annoying. :)
With that said, based on what I do know about them, I don't think the pitch matters as long as your brain hears the pattern with the appropriate timing.
