Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.
Command
$ sb get 3QQ3C1V2VY@1 --preset cold -o mountain-summit.wav
How it's made
Source
a steady, cold wind at altitude. Thin air and a bare summit mean little low-frequency turbulence and nothing to rustle, so the wind is a quiet, slowly drifting pink-noise veil in a band of ~600 Hz-4 kHz, decorrelated left and right for a wide, open field.
Air
a very faint, high "hiss of space" (5-9 kHz) that is the only sound left when the wind drops, which is what makes the silence feel vast.
Edge tones
wind skimming bare rock edges produces two soft, narrow breathy tones (1-2.5 kHz) whose pitch wanders slowly and which only wake during stronger gusts.
Gusts
sparse (periods of ~10-30 s) swells lift level and brightness together; between them the wind falls to a low, steady floor. No reflections: no reverb, no echo, no tail.
Variation
a slow independent drift moves the band centre so the wind never sits still.
