About tone generation

A tone generator holds one tone in the room and lets the figures circle around it. Somewhere near 20Hz, sound begins to behave like pressure more than note, and by 10kHz it has already narrowed into something finer and less willing to stay put. In this case the browser does the shaping itself through the Web Audio API, so the tone arrives with very little distance between asking and hearing.

Waveform types

A sine wave is the plainest version of a tone, almost bare, with very little clinging to it. A square wave comes in corners, carrying odd harmonics that give it a hollow, clipped body. A sawtooth wave keeps more of the upper grain, so it feels brighter and more exposed. A triangle wave sits close to sine, though not fully smoothed out, as if a few edges were left behind on purpose.
