Audio Signal Generator

Plays steady tones and modulates them at an exact low rate you choose — as a frequency offset between the ears (binaural), a loudness pulse (isochronic / monaural), an opposite phase wobble in each ear (ipm), or a level swing between the ears (ild). The readouts and the visualizer state precisely what the signal contains. It generates and measures signals — it makes no claims about what listening to them does.
