Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.
Command
$ sb get FGPKRCB2NM@1 --preset loaded-heel -o combat-boot-stomp.wav
How it's made
Source
a heavy rubber combat-boot heel strikes a hard floor; the forefoot loads 22-48 ms later. Filtered noise contacts last 12-32 ms, with a rounded 1-2 ms attack instead of a digital impulse.
Body
sole compression excites broad 65-220 Hz noise and damped floor modes near 83, 147 and 263 Hz. Their 80-230 ms T60 decays give weight without a pitched bass drop or a hollow drum ring.
Leather
upper folds rub under load in two uneven pulses between 18 and 210 ms; moving 450-1500 Hz noise bands with irregular 65-110 Hz amplitude flutter model dry stick-slip creak, not a pure squeak.
Envelope
the heel leads, the quieter forefoot tightens the punch, and leather settles after contact. All layers decay naturally before a 340-410 ms safety fade; the half-second render ends silently.
Variation
named random streams vary contact timing, mode tuning by 3%, friction and pressure flutter. Weight changes damping and low-body balance; hardness changes contact bandwidth and duration.
Presets
concrete is balanced and dry; tile emphasizes the hard sole slap; loaded heel adds low weight; planted leather emphasizes upper flex and a more separated forefoot. All are close, dry mono foley.
