- The page calls 432 and 528 Hz tuning traditions “lore” and says brainwave effects remain under study, not medicine.
Field notes
The generator exposes sine, triangle, square, and saw waves, with binaural and isochronic modes sharing a beat-rate control; its note recommends headphones for binaural playback and isochronic beats on speakers. The 40 Hz option is described as 1 ms clicks of a 10 kHz tone, fixed at the study protocol's pitch, with the page characterizing evidence as mice plus early human trials. The Chladni plate is listed as free, while other live visualizers sit in Pro.
