Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.
Command

How it's made
Source
raindrops strike a fabric canopy overhead; Poisson noise impacts at 24–145 drops/s.
Body
yielding cloth makes broad, damped 380–1500 Hz drumlets lasting 22–65 ms, not metallic rings. A 1–4 ms contact transient darkens from 3–7 kHz to 1.2 kHz as the water spreads on the cloth.
Layers
quiet stereo rain wash at 650 Hz–6 kHz surrounds the close canopy; lower ground splashes are 15–55 ms noise sprays at 1.4–5 kHz, with occasional delayed 8 ms secondary droplets.
Envelope
steady 10 s loop with only ±8 percent slow density drift; renderer crossfades the seam. Every drop has a rounded 0.5–1.5 ms attack and exponential decay, avoiding hard impulse clicks.
Variation
independent seeded timing, strength, pan, filter centres and decay for every drop. Density controls rainfall, tension raises and shortens cloth drumlets, ground brings splashes forward.
Presets
sparse soft drizzle, higher tight-canopy taps, dense heavy rain, and open wet-ground splashes.
