How it's made
- Source
- a small bolt of arcane energy modelled as a pitched "singing" core (a sine plus a soft triangle one octave up) that glides upward as the bolt accelerates, wobbling a few cents as it steers toward its target.
- Body
- a band-passed pink-noise wake (Q ≈ 3) follows the core pitch at 1.5x, giving the zippy airy whoosh; a trail of tiny 3–9 kHz sine pings, each 20–60 ms long, sheds behind it like sparks and thins out over time.
- Envelope
- the core swells in 40 ms, holds as the bolt closes in, then is cut by the impact; the whoosh peaks just before impact; the soft pop is a 2 ms noise tick plus a sine dropping 420 → 90 Hz over 90 ms.
- Variation
- `rng` shifts the pitch by ±3 %, the wobble phase and every spark's pitch, timing and pan; macros set length, pitch, wobble depth, sparkle density and pop weight; presets change these physically.
| Parameter | Range | Default | Unit | Controls |
|---|---|---|---|---|
| length | 0.4 – 1.2 | 0.8 | s | Flight time |
| pitch | 0 – 1 | 0.5 | — | Pitch |
| wobble | 0 – 1 | 0.4 | — | Homing wobble |
| sparkle | 0 – 1 | 0.6 | — | Sparkle trail |
| pop | 0 – 1 | 0.5 | — | Impact pop |
| travel | -1 – 1 | 0.6 | — | Negative values travel right to left |
| seed | int | 1 | — | Variation, reproducible |
