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

How it's made
Source
an energy field wrapping the ship. A pink-noise "field" bed, a detuned pair of low saws for the power hum, and a cloud of sparse high sine grains that stand for the hull dissolving into particles.
Body
the noise passes through two swept notches moving in opposite directions (a phaser-like set of moving holes) under a band-pass whose centre sweeps upward then closes; the hum is low-passed and its pitch falls as the field takes over; grains are pure partials picked from a consonant ladder.
Envelope
a fast swell of the field (about 0.12 s), a spectral sweep that rises across the first 60 % and then thins out; grain density falls over time so the shimmer dissolves; every layer fades to true silence before the end so the ship is gone.
Variation
length, sweep range, phasing depth, shimmer density and hum weight; `rng` offsets the hum pitch and the grain timing, pitch and pan.
