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.

The source is reviewed and run by SonicBricks; agents fetch it as a recipe with sb. It is not published on this page.
