How it's made
- Source
- three events in sequence. (1) Dry hinge friction as the lid is lifted: a stick-slip sawtooth whose pitch climbs with the opening speed, plus a rasp of band-passed noise. (2) The lid reaching its back stop: a dull thump. (3) The reveal: a rising, bell-like chord of stretched sine partials with a few random glints.
- Body
- the creak is shaped by the wooden box cavity (two resonances around 380 Hz and 900 Hz) and rolled off above 3 kHz so the saw never turns shrill. The thump is a pitch-dropping sine (110 → 50 Hz) plus a damped wood-mode strike. The chord notes are a fundamental, 2.01x and 3.02x partials; the upper ones decay faster.
- Envelope
- creak swells over 0.1 s, holds with irregular stick-slip pulses and cuts off at the stop; the thump decays in 0.25 s; chord notes strike in 3 ms and ring for about 1 s, staggered 70 ms apart.
- Variation
- `rng` jitters the stick-slip pattern, mode tuning, note detune and glint times.
