Footstep on Thick Carpet

How it's made

Source

a soft sole compresses thick carpet in two overlapping contacts, heel then forefoot 65-105 ms later. Filtered noise models distributed pile compression rather than a hard point impact.

Body

broad, low-Q pressure bands at 95-180 Hz and 230-360 Hz decay within 120-180 ms; no ringing floor.

Fibres

pink-noise friction spans 450-2200 Hz, darkening during release as bent pile stops sliding. A delayed, weaker brush models sole roll and optional toe drag; there are no discrete clicks.

Envelope

rounded 14-27 ms attacks, overlapping heel/toe releases and a 220-300 ms brush. All energy fades by 330 ms with a silent tail to 400 ms. The recording is dry and centred.

Variation

seeded contact spacing, band tuning and noise grains change each step. Load sets pressure, pile sets absorption and softness, and brush sets the amount and duration of sliding friction.

Presets

sock tiptoe is brush-led, soft sole is a balanced walk, deep pile is darker and slower, and toe drag extends the fibrous release without introducing a hard heel strike.
