OpenBCI Video

OpenBCI into Touchdesigner via OSC mapped to Sine Wave

This is a rudimentary demo of an OpenBCI signal (in this case, FFT of channel 5) mapped to an audio generator (Sine wave generator).

As I move my arm the frequency tends to go up, though there is not any fine control at this point. But there is a clear difference between the at rest tones and more excited tones with arm movement.

The base frequency of 420 Hz is manipulated +/- the re-ranged values coming from the BCI input. A similar normalized value is used for the circle radius (which is hard to see here since it ranges outside the viewer most of the time). This continues what I demonstrated here:
