What it is
Brown noise and pink noise generation — locally synthesized, no streaming required. Sensory Diet Synthesizer is a core component of the P31 Labs sovereign cognitive infrastructure stack — built to run offline, deployed to the edge, and designed without dark patterns.
Brown/pink noise generated from white noise via IIR filter in Web Audio API. Binaural beats use two OscillatorNodes with 40 Hz offset. WebGL color field is a fragment shader with simplex noise.
Core features
Brown noise and pink noise generation — locally synthesized, no streaming required
Binaural beats: delta (2 Hz), theta (6 Hz), alpha (10 Hz), gamma (40 Hz)
Slow-breathing color bath: WebGL color field that cycles at breath rate
Over-stimulated vs. under-stimulated calibration: different presets for each state
