Boot on Cobblestone

How it's made

Source

a boot heel excites stone with a 2-6 ms filtered noise strike; the sole follows 65-120 ms later.

Body

embedded cobbles have damped, inharmonic modes at 430, 790, 1380, 2310 and 3670 Hz, T60 18-65 ms. A broad 100-380 Hz pressure thump represents boot and ground loading, without a pitched bass drop.

Layers

heel is dominant; the softer sole rolls onto the uneven surface, with 9 irregular grit contacts and a broken friction bed at 650-5700 Hz. The friction darkens as the sole loses sliding speed.

Envelope

rounded sub-ms strike onset; grit rises after contact and dies by 280-350 ms; zero by 400 ms.

Variation

seeded tuning +/-4%, heel-to-sole timing +/-9%, grain timing, bandwidth and strength vary. Hardness changes contact bandwidth; weight adds loading; scuff extends friction; pace shortens the roll.

Presets

everyday leather boot, heavy planted tread, brisk hard heel, and a loose-grit dragging step.

Space

close mono foley with no reflections or reverberation; stone modes are local material vibration.
