Time Rewind Spell

How it's made

Source

a reversed magical swell. Pink noise and a stack of detuned sines are played "backwards": the level grows slowly and exponentially to a peak at about 72 % of the length, then is cut off by the release.

Body

the noise passes a band-pass (Q ≈ 1.5) whose centre climbs from 250 Hz to 5 kHz, like tape being wound back; the sine stack (partials 1 : 1.5 : 2 : 3, ±0.4 % detune) rises from 220 Hz to 1.3 kHz and adds a soft chorus-like shimmer.

Ticks

a clock escapement running backwards. Each tick is a high-passed noise click on a 4.5 kHz steel resonance with a slow 10 ms attack and a 1 ms drop (a reversed click). The beats accelerate from ~9 to ~30 per second and swell with the main envelope.

Release

the sucking pull-in is a noise band whose centre falls from 6 kHz to 150 Hz in ~0.5 s together with a falling sine (900 → 70 Hz) and a short low thump at the very end; a closing fade guarantees a clean tail.

Variation

`rng` jitters tick timing and level, the swell peak time and the sine tuning; presets change length, tick density, shimmer and darkness.
