How it's made
Source
a heavy limp, cloth-covered weight slides over floorboards in three uneven pulls. Pink friction at 65-2400 Hz carries the load; filtered white noise supplies fabric at 650-5200 Hz.
Body
soft 12-22 ms contacts excite floor modes near 92, 173, 307 and 491 Hz, T60 55-170 ms. Broad low-frequency contact noise adds weight without a pitched bass oscillator or long room tail.
Envelope
pulls rise in 40-100 ms, sag and resume, then release in 100-220 ms; total about 3 s. Short secondary scuffs and delayed soft bumps follow each pull as the limp load catches up.
Modulation
shared pull pressure drives friction level and cutoff; random 8-19 Hz micro-slip and slower 3 Hz wander break up the scrape. Cloth folds lag pressure by 25 ms.
Variation
seeded timing, contact strength and mode tuning vary independently; mass lowers modes. Roughness changes grain and brightness; cloth changes rustle balance; gait changes pull timing.
Presets
labored haul, cloth-wrapped slide, snagging pulls and bare-board weight vary rhythm and layers. Dry mono contact keeps the effect placeable; 35 Hz high-pass and a final fade remove DC and clicks.
