Moth at the Lamp Shade

How it's made

Source

thin wings displace air and brush a fabric-covered shade; filtered noise models papery friction. Smooth 22-45 Hz wing strokes occur inside irregular 0.22-0.85 s bouts, with a weaker return stroke.

Body

broad friction bands move around 1.3-3.6 kHz; a low-pass at 3.2-6.2 kHz softens the paper edges. Shade contacts excite short, damped modes near 430, 970 and 1830 Hz, lasting 25-65 ms, without a ring.

Envelope

bouts rise over 15-35 ms and taper over 80-170 ms; individual contacts have 3-6 ms attacks. One to three light taps follow the flutter within each bout, so collisions belong to the wing motion.

Events

random bouts at 0.45-2.1/s breathe slowly; jittered visits every 2-5 s limit long empty gaps.

Variation

per-bout speed, filter sweep, duration, tap timing and strength vary from seeded streams. Macros control activity, wing speed, paper brightness, contact balance and a narrow nearby stereo field.

Presets

hesitant isolated brushes, restless rapid flutter, soft fabric rubbing and distinct paper taps. Dry close perspective, no lamp hum or room bed; -33 LUFS preserves the small scale and transient headroom.
