$ sb get D230CTK8WZ@1 -o short-noise-uplifter.wav

Source: a stereo air-noise bed (two decorrelated white/pink mixes) that stands for the turbulence of a rushing, tightening gesture; a thin rising band of the same noise adds the bright "shimmer" on top.
Body: a high-pass whose cutoff climbs exponentially (about 250 Hz to 7 kHz) so the low end thins out while the energy moves up; a band-pass shimmer at 2.5x the cutoff gives a bright, slightly airy edge. An optional soft tonal layer (two detuned saws through an opening low-pass) rises with the noise for a more musical lift.
Envelope: a quick exponential crescendo that peaks at about 92 % of the length, then a short release (about 70 ms) so the riser ends cleanly on the downbeat instead of with a click.
Variation: length, start/end brightness, tone amount and stereo width; `rng` shifts the peak time by a few percent and the noise streams stay decorrelated.

Parameters
Parameter	Range	Default	Unit	Controls
length	0.4 – 2.5	1	s	Length
brightness	0 – 1	0.6	—	Peak brightness
start	0 – 1	0.3	—	Higher values start the rise from a thinner, higher noise
tone	0 – 1	0.15	—	Tonal lift
width	0 – 1	0.7	—	Stereo width
seed	int	1	—	Variation, reproducible

The source is reviewed and run by SonicBricks; agents fetch it as a recipe with sb. It is not published on this page.
