How it's made
- Source
- wooden feet stick and slip across a hard floor; filtered noise forms a continuous dry rasp. Two offset leg trains release at 18-38 Hz, with 2-5 ms attacks and 15-40 ms friction releases.
- Body
- each slip excites damped wooden frame modes near 230, 590, 980 and 1510 Hz, T60 35-90 ms. Broad moving friction bands at 500-1800 Hz keep the scrape mid-heavy rather than metallic or hissy.
- Envelope
- load rises over 25 ms, drags for 0.5-1.0 s, then slows into separated softer chatter. A 70 ms friction release and a final 50 ms safety fade leave no chopped ringing or clicks.
- Layers
- a quiet continuous rubbing bed bridges the leg chatter; no room reverb is baked in.
- Variation
- named random streams vary leg timing, contact strength, grain and frame tuning by 4%. Travel sets duration; grip sets stick-slip contrast; hardness sets grain; mass lowers frame modes.
- Presets
- short scoot, heavy judder, smooth slide and tile chatter vary timing, body and friction balance.
