How it's made
- Source
- packed canvas meets the floor over 6-15 ms; low-passed noise models compressed filling and air.
- Body
- broad, damped 65-240 Hz pressure bands carry weight, not a pitched bass drop. Wood adds a short 175/340 Hz floor response; tile adds a restrained 1.6 kHz contact, carpet absorbs both.
- Envelope
- the primary thud dies in 180-300 ms; filling shifts in a weaker contact 90-170 ms later.
- Fabric
- three overlapping 250 Hz-4 kHz friction lobes slump and darken over 0.15-0.70 s as folds settle.
- Hardware
- four diminishing contacts at 65-370 ms excite inharmonic 2.1/3.3/4.9/6.4 kHz buckle modes; each has a 1 ms rounded attack and 50-170 ms decay, with upper modes damped fastest.
- Variation
- seeded timing, tuning and strength vary independently. Weight changes pressure and damping; slump changes fold timing, hardware controls buckle activity, and the four presets vary the floor/load.
- Space
- dry and close, with a narrow spread on cloth and hardware; all motion fades before 0.95 s.
