City Street Rain

How it's made

Source

distant pavement impacts merge into stereo pink/white noise, high-passed at 420 Hz; nearby drops add random 1.2-6 kHz noise splats with 0.7 ms attacks and 7-30 ms decays.

Body

shallow gutter turbulence occupies 140-1500 Hz, with small 1.8-5 mm entrained bubbles; broad filtering and short damping avoid a pitched drain whistle.

Traffic

wet tyre spray swells over 0.8-1.5 s and recedes over 2-3 s, with a lower rolling layer; approaching spray opens from 1.2 to 6.5 kHz, then darkens while crossing the stereo field.

Envelope

rain breathes on a 0.12 Hz random drift; gutter flow wanders independently at 0.35 Hz. Passing vehicles arrive every 7-21 s with jitter, not a continuous undifferentiated hiss.

Space

opposite building fronts give quiet 47/93 ms reflections, low-passed at 2.8/1.9 kHz; no long reverberant tail is added to the outdoor scene.

Variation

seeded drop strength, colour, length and position; tyre direction and speed vary per pass. Presets separate quiet backstreet, busy avenue, close gutter and dense downpour balances.
