How it's made
- Source
- a fighter's drive. A stack of three slightly detuned band-limited saws plus a sub sine make the roaring engine tone; a high sine pair is the turbine whine; pink noise is the exhaust and the air torn around the hull.
- Body
- every tonal layer is scaled by one Doppler curve: it holds high while the ship approaches, falls fast through the pass and settles low as it leaves. A low-pass opens on the approach and closes on the way out (air absorption), and the noise band-pass sweeps up and down with the same curve. The saw stack is soft-saturated for the growl.
- Envelope
- the level builds slowly over the approach (inverse-distance swell), peaks just after the pass at about 50 % of the length and falls away faster; the ship travels across the stereo field in step, with a decorrelated wide noise bed so the roar surrounds the camera.
- Variation
- length, pitch, roar, whine, brightness and travel; `rng` shifts the pass time and the detune a little.
| Parameter | Range | Default | Unit | Controls |
|---|---|---|---|---|
| length | 1.6 – 5 | 3 | s | Length |
| pitch | 60 – 260 | 120 | Hz | Engine pitch |
| roar | 0 – 1 | 0.6 | — | Roar |
| whine | 0 – 1 | 0.4 | — | Turbine whine |
| doppler | 0 – 1 | 0.6 | — | Doppler depth |
| brightness | 0 – 1 | 0.5 | — | Brightness |
| travel | -1 – 1 | 0.8 | — | Negative values travel right to left |
| seed | int | 1 | — | Variation, reproducible |
