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

How it's made
Source
faint air leaking through roof seams; independent pink and white turbulence in stereo, band-limited to 90-4800 Hz, breathing with 5-30 s gusts rather than a constant noise floor.
Body
roof panels flex under changing pressure. Filtered friction excites sliding inharmonic bands near 230-1800 Hz, plus fixed sheet modes at ratios 1:1.53:2.37:3.91 with 0.8-2.8 s decays.
Envelope
sparse creaks every 5-13 s with irregular timing; 80-180 ms onset, two friction lobes, 0.7-1.5 s release. Smooth envelopes avoid turning stress releases into hard impact clicks.
Space
29/47 ms early reflections feed a diffuse hall tail, 3.2-6.2 s decay; high frequencies absorb faster. The long return is integral to the empty building, not an added musical effect.
Variation
seeded panel size, friction duration, tuning, strength and position change per event. Draft, roof activity, panel size and room decay distinguish sheltered, open, tall and cooling spaces.
