How it's made
- Source
- a hard shoe heel strikes concrete with a 0.35 ms attack and 11–19 ms noise click. The forefoot lands 58–126 ms later with a softer, broader contact, followed by toe friction.
- Body
- a massive concrete slab radiates no sustained pitch; broad 170–700 Hz contact noise models sole compression for 35–55 ms. No oscillators, narrow modes, room tail or reverb.
- Spectrum
- heel energy spans 0.7–8 kHz, darkening over 25 ms as the contact patch expands; toe friction falls from 4.4 to 1.7 kHz over 65–135 ms as sliding speed dies away.
- Envelope
- a sharp heel, delayed toe and asymmetric scuff decay finish before 0.29 s; a smooth safety envelope closes at 0.30 s, leaving a silent tail within the 0.4 s render.
- Variation
- named random streams vary contact timing by 5%, filter colour by 6%, and toe force. Presets change heel hardness, sole load, heel-to-toe timing and friction independently.
| Parameter | Range | Default | Unit | Controls |
|---|---|---|---|---|
| hardness | 0 – 1 | 0.75 | — | Heel hardness |
| load | 0 – 1 | 0.45 | — | Sole load |
| pace | 0 – 1 | 0.5 | — | Roll speed |
| scuff | 0 – 1 | 0.35 | — | Toe scuff |
| seed | int | 1 | — | Variation, reproducible |
