Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.
Command
$ sb get G6PQRB5CA0@1 --preset side-vent -o microwave-running.wav
How it's made
Source
a running microwave: transformer vibration at 50/60 Hz and dominant 100/120 Hz harmonics, cooling-fan turbulence, blade passage, and the loaded glass turntable rolling on its support ring.
Body
the sheet-metal enclosure colours airflow at 430 and 920 Hz with broad, damped resonances; transformer partials fall rapidly above 600 Hz. Roller friction occupies roughly 65–420 Hz.
Envelope
continuous operation, without switching, beeps or door sounds. An 8 s revolution gently modulates roller pressure; three support rollers add a softer 0.375 Hz undulation, never impacts.
Modulation
fan blades pass at 240–360 Hz with 0.25 Hz pitch flutter below 0.3 percent and gentle 0.5 Hz air flutter. Vent colour breathes by 3 percent over 8 s; no exaggerated wind gusts.
Variation
seeded independent air and bearing noise, plus seeded cyclic phases. Mains is 50 or 60 Hz; fan, hum, platter load and vent openness set source balance, spectral tilt and blade speed.
Presets
compact fan-led 60 Hz, transformer-led 50 Hz, exposed bright side vent, and loaded platter. Sources stay close and nearly mono; no room reverb. Periodic layers complete whole cycles in 8 s.
