Wormhole Opening

How it's made

Source

spacetime tearing open, heard as four layers. A brief fabric-rip transient (high-passed noise burst), a swirling roar of turbulent pink noise, a rising resonant core (detuned saws plus a resonant noise band that climbs together), and a sub-bass bloom (sine plus brown-noise rumble) that swells into the opening.

Body

the roar runs through a band-pass whose centre rises exponentially from 180 Hz towards the top while a slow-then-faster modulation swirls it; left and right use independent noise and opposite modulation phase, so the vortex circles the listener. The core resonance follows the same rise at a fraction of the level, Q bounded to stay smooth. The sub drifts upward into the bloom, as pressure builds and releases.

Envelope

slow swell to a thunderous peak at about 45 % of the length, then a long dark decay; the highs close down after the peak so the tail is a low rumble. A 4 ms attack on the rip keeps it click-free.

Variation

length, swirl speed, brightness, sub weight and resonance tension; `rng` offsets tuning and the peak time by a few percent.
