Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.

How it's made
Source
the untuned receiver of an analogue TV picks up thermal and atmospheric noise: broadband white noise from the tuner front end, plus a thin low-level mains-related buzz from the deflection circuits.
Body
the audio stage band-limits the noise (high-pass ≈ 80 Hz, low-pass 6–14 kHz) and a slow-moving band emphasis around 2–4 kHz makes the hiss shimmer; sparse unipolar impulses (high-passed at 1.5 kHz) add the crackle of static discharge.
Envelope
a channel change is a hard cut: a 2 ms attack, a slightly hotter first 40 ms while the tuner re-locks, a flat sustain with irregular level flutter (about 25 Hz, from lowpassed noise), then a 6 ms release so the cut is abrupt but click-free.
Variation
`rng` varies the crackle pattern, the flutter and the band-emphasis wander; macros set length, brightness, crackle amount and the buzz level; presets span a short clean cut, a standard channel change, a dark far-station hiss and a crackly storm.
