How it's made
- Source
- air pushed gently as a panel rises into view: decorrelated pink noise in left and right channels, high-passed at 250 Hz so there is no rumble.
- Body
- a wide band-pass (Q ≈ 0.7) whose centre opens upward from about 700 Hz to 2.5-5 kHz while the panel settles, giving the "bloom"; a second, narrower band follows it slightly higher for a touch of breath.
- Glint
- one soft tonal sparkle, a sine with a quieter inharmonic partial (ratio ≈ 2.4), starting just after the swell begins and ringing out in the tail, never sharp.
- Envelope
- smooth fade-in over about 55 % of the length (curved), a short release; the glint has a 6 ms ramp.
- Variation
- `rng` detunes the glint by ±2 % and shifts the swell peak by a few percent.
