Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.
Command
$ sb get 31H44GQZ7J@1 --preset airy -o respawn.wav
How it's made
Source
a reversed-reverb style swell. Pink noise is band-passed by a centre that rises from 300 Hz to about 5 kHz as the avatar "assembles"; a bed of detuned sine partials (the shimmer) supplies the pitched part.
Body
eight sine partials on a major-add9 stack (root, 3rd, 5th, octave, 9th) start spread by up to 3.5 % and converge onto exact pitch at the landing moment, with a 7.5 Hz shimmer tremolo that fades out.
Envelope
noise and shimmer grow on a convex curve (exponent 2.5) to a peak at 55 % of the length. The landing is a soft sine trio (root, fifth, octave; 10 ms attack, exponential decay) with a faint low-passed noise thump.
Variation
`rng` shifts the landing time by a few percent and the start detune of every partial; the presets change the root pitch, the length, and the balance of air, shimmer and landing tone.
