Source: air dragged around a spinning column: two decorrelated pink noise beds (one per ear), high-passed at 140 Hz, plus a faint tonal whirl of resonant air that follows the same rising pitch curve.
Body: a band-pass whose centre moves with the rotation phase (a Doppler-like brightness swing once per turn) on a rising base sweep, followed by two swept notches that make the rotating phasing; a low-pass opens and closes with the "behind the head" half of each turn so the front of the circle sounds brighter.
Envelope: the rotation accelerates from `startRate` to a faster rate in turns per second (a chirp, so the phase is continuous); the level swells to a peak at about 70 % of the length, then falls quickly to silence. Each ear's level follows the sine of the rotation angle, so the sound circles the head.
Variation: length, brightness, acceleration, spin direction, phasing depth and whirl tone; `rng` offsets the start phase and the peak time by a few percent.

Parameters

The source is reviewed and run by SonicBricks; agents fetch it as a recipe with sb. It is not published on this page.
