How it's made
Source
curtain rings scrape a rail while folds rub together; filtered pink and white noise model the cloth and sliding friction, with 12-25 irregular, softly attacked ring contacts per pull.
Body
short inharmonic ring bands at 1.3, 2.2 and 3.7 kHz decay over 18-65 ms; a broad 350-1500 Hz cloth band gives weight. Metal raises the contact brightness; damped runners suppress ringing.
Envelope
a 60 ms pickup, accelerating slide and slowing finish occupy 0.85-1.55 s; fabric lags behind the rings, then folds settle over 150 ms. A low-passed 70 ms end-stop stays below the slide.
Events
contacts bunch toward mid-travel, then two quieter contacts mark rings gathering at the stop.
Variation
seeded timing, contact strengths, tuning and fold flutter; length, fabric weight, ring metal and contact count distinguish sheer runners, brass rings, velvet and a brisk opening.
Space
dry close perspective, with a modest left-to-right traverse and no added room reverb.
