How it's made
Source
leather folds rub under load; band-limited pulses at 65-190 Hz model repeated stick-slip releases, with irregular speed and pressure. Filtered noise supplies the sliding surface grain.
Body
broad, damped bands around 220-430 Hz and 650-1900 Hz colour the flexible hide; no metal ring.
Envelope
three unequal flexes overlap within 0.65-1.05 s, each with a 15-45 ms pressure rise and soft release. The middle flex is strongest, and the final relaxation is shorter and quieter.
Modulation
slip rate rises then falls with movement; independent smooth jitter perturbs rate and contact amplitude. Moving mid bands track tension, keeping the squeak tight rather than whistling.
Layers
low fold friction, resonant stick-slip and fine 0.8-4 kHz surface rub; dry mono close foley.
Variation
seeded rate offsets and random pressure wander; tension changes pitch, grain changes roughness, body changes hide thickness, and movement changes the action length.
Presets
jacket bend, heavy saddle shift, taut seam squeak and supple worn leather vary all layers.
