How it's made

Source
bent book leaves slip off a thumb, each releasing a 1-3 ms filtered noise tick at 2-6 kHz.
Body
flexible paper recoils as broad 450-1800 Hz noise, damped within 18-45 ms, without pitched ringing.
Layers
each release drags a 20-55 ms fibrous scrape behind it; a quiet 700-3500 Hz friction bed connects the leaves. Thicker stock lowers the bending band and strengthens the individual flaps.
Envelope
18-52 releases accelerate by about fivefold over 0.85-1.5 s, swelling then relaxing as the thumb clears the book. A soft last-leaf settling rustle dies within 110 ms; no card bridge or closing impact.
Variation
seeded timing jitter, strengths, filter tuning and narrow pan keep the flutter irregular. Presets contrast thin dense leaves, worn fibrous paper, sparse thick stock and a brief fast search.
Space
dry close perspective; high-pass at 180 Hz, rounded attacks and low-pass below 8 kHz avoid rumble and brittle edge fizz. The final 100 ms is silent.
