Thunderstorm Bed

How it's made

Source

thousands of rain impacts merge into independent stereo pink and white noise; nearby ground splashes are 1-3 ms attacks with 8-25 ms decays, scattered at 25-100 events per second.

Body

rain occupies 450 Hz-8 kHz. Thunder is turbulent pressure noise, not a pitched oscillator: a 35-240 Hz body, 90-650 Hz rolling branches and a brief 180-1800 Hz arrival.

Envelope

steady rain breathes by 10 percent over several seconds. Thunder arrives every 7-17 s, with 80-650 ms attacks and irregular secondary swells over 6-10 s as channel segments arrive.

Propagation

distance softens the arrival, removes upper frequencies and lengthens the roll; later branches are darker. Low frequencies stay near centre while rain and delayed rolls spread.

Variation

seeded timing, distance, strength, envelope lengths and pan differ for every discharge. Presets cover distant rain, balanced storm, close heavy squalls and a receding weather front.

Long arc

a slow rain drift and a 30 s broad storm crest preserve the bed between thunder rolls; receding weather progressively darkens and weakens the thunder without stopping the rain.
