Are there any puredata patches?
I don't know anything about that.
The concept is pretty simple, so you should be able to deal with binaural beats in any environment.
- Play pink noise at volume 10.
- Play a sine wave at 100 Hz at volume 90 in one channel.
- Play a sine wave at 100.5 Hz at volume 90 in the other channel.
100 Hz is the carrier frequency. 0.5 Hz is the entrainment frequency.
In the SBaGen timings, "->" slides frequencies to the target so that there isn't an abrupt change.
