How it's made
Source
a message leaving an outbox, heard as air rushing past (pink noise, high-passed at 300 Hz) plus a small bright tonal flick as it clears the edge (two sine notes with a stretched inharmonic partial).
Body
the air layer goes through a band-pass (Q ≈ 1.4) whose centre rises quickly from ~500 Hz to 3.5–7.5 kHz over the first 90 ms; the flick notes ring like a tiny glass bell, partial ratio ≈ 2.76.
Envelope
whoosh swells over ≈ 90 ms and releases into an airy 60–250 ms tail; the flick notes start 70 ms and 105 ms in (a rising interval), 2 ms onset ramp, 70–110 ms decay; the whole sound ends by about 0.35 s.
Variation
`rng` detunes the notes by ±1.5 %, shifts the whoosh peak by a few percent and decorrelates the left and right air streams; presets change tail, brightness, interval and flick weight.
