Dry Sand Footstep

How it's made

Source

dry beach grains slip and collide under a foot; filtered noise supplies fine friction, with 170-340 irregular grain clusters per second, each softened over 1-13 ms.

Body

yielding sand absorbs the strike; broad noise bands at 90-350 Hz model sole compression, without a pitched cavity or a hard heel click. The forefoot follows the heel by 65-120 ms.

Envelope

heel pressure rises in 12 ms; forefoot pressure in 22 ms. Grain friction peaks twice, then falls over 180-300 ms as displaced grains settle. Output fades fully by 450 ms.

Spectral movement

the contact band opens from 1.4 to 3.6 kHz, then darkens below 1.2 kHz; an overlapping 600-2400 Hz scrape follows the rolling foot. No room reverberation is added.

Variation

seeded grain timing, grain colour, strength and contact spacing vary each step. Weight changes compression, grain size changes texture, drag changes displaced sand, pace changes roll.

Presets

barefoot is soft and fine; walking is compact; deep sand is heavy and slow; toe drag has a lighter body and a longer, brighter sand displacement.
