Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.
Command
$ sb get K0BG36CE1X@1 --preset long-overhang -o ruler-twang.wav
How it's made
Source
a ruler released over a desk edge; a 3 ms finger scrape excites a bent cantilever.
Body
a 65-180 Hz bending fundamental and short modes at 6.27 and 17.55 times its frequency; a lightly buzzing clamp adds harmonics 2-7. Desk modes at 185, 430 and 970 Hz decay in 55-140 ms.
Modulation
geometric tension relaxes over 180 ms; 12-21 Hz pitch wobble and radiation flutter lose most of their depth in 300 ms. Upper harmonics decay faster than the bending fundamental.
Envelope
2 ms rounded release, 0.48-0.86 s fundamental T60, with a soft final fade by 0.96 s.
Variation
seeded tuning varies by 1 percent and wood modes by 3 percent. Overhang sets pitch; bend sets wobble and buzz, damping sets ring time, and desk controls transferred woody energy.
Presets
long overhang is low and floppy; short overhang is tight and bright; loose clamp buzzes; palm damping yields a short muted wooden twang. The sound is dry and centered.
