Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.
Command
$ sb get Y5S1SJC89B@1 --preset torch-hiss -o laser-beam-loop.wav
How it's made
Source
a continuous cutting beam. The emitter's power stage hums as a mains-locked buzz: two slightly detuned saw oscillators near 160 Hz (beating at ~1.5 Hz) plus a square sub an octave lower for weight.
Shimmer
the beam's plasma flickers; a 2.3–3.4 kHz tone pair is amplitude-modulated at 20–28 Hz (whole cycles per 4 s) so it fizzes rather than sings, and a slow drift moves the carrier pitch.
Sizzle
where the beam meets the target, vaporised material spits as fine high-passed noise (above 4.5 kHz) plus sparse crackle impulses; a band-limited noise around 2.8 kHz breathes with the cut.
Envelope
held on target, so the level is steady; only slow drift (0.3–0.6 Hz) of the buzz filter cutoff and of the sizzle level keeps it alive. The loop length holds whole modulation cycles.
Variation
`rng` sets the detune, the drift paths and the crackle pattern; presets change the pitch, buzz brightness, shimmer depth and sizzle amount (thin cutter, heavy industrial beam, hissing torch).
