wind

The hill's own wind: filtered noise with slow gusts and two thin resonances — the keening a gap in a cairn makes — crossfaded head-to-tail so the loop has no seam.

7.9 s, 22.05 kHz, mono, stored as PCM rather than Opus, because an Opus clip loses its first few milliseconds on decode and a bed that loops would click there.

game.world.Hillside plays it from two spatial sources: wind_summit over the cairn at full pitch, and wind_tarn down in the hollow at 0.62 pitch, which is what makes the low ground sound like low ground.
