Leaf Pile Dive

How it's made

Source

a body compresses a deep leaf pile; low-passed pink noise models the soft air/ground thump. Independent friction noise and filtered micro-impulses model sliding faces and buckling dry edges.

Body

a broad 95-180 Hz pressure band dies within 0.35 s; leaf friction fills 450 Hz-7 kHz with low-Q colour, avoiding a pitched cavity. Dry edges are brighter; damp leaves absorb the upper band.

Envelope

contact rises in 18 ms, leaf displacement peaks at 90-170 ms, then collapses by 1.2 s. A weaker secondary shuffle at 0.4-0.7 s models the body sinking into the pile, not a second jump.

Events

38-78 seeded leaf contacts cluster near the impact and spread out to 2.22 s; each has a 1.5-5 ms attack and 12-65 ms release. Late contacts become softer and individually distinguishable.

Modulation

friction pressure opens the low-pass from 2-3 kHz to 4-7 kHz and closes as leaves settle; independent 19/27 Hz random flutter breaks up the wash. Fine edges follow the same pressure envelope.

Variation

dryness controls edge/friction balance and bandwidth, depth lengthens sinking and adds low pressure, force increases displacement and contact count. Seed varies contact times and positions.

Presets

light hop, brittle dry scatter, deep engulfing dive, and darker damp leaves. Dry close stereo; no environmental bed or reverb. A final smooth envelope reaches zero before the 2.5 s boundary.
