Command

$ sb get PR0KBS4DGG@1 -o wind-through-tree-hollows.wav

Source: turbulent air (pink noise).
Resonators: N hollows, each a narrow resonance with an inharmonic "wooden" overtone (≈ Helmholtz cavity).
Modulation: one gust envelope raises each hollow's pitch and level; hollows follow one another with a delay (前者唱于而随者唱喁), and only strong wind wakes the higher-numbered ones (泠风小和，飘风大和).
Layers: hollows · low rumble of the air · leaves (use foliage/rustle) · twig snaps (events, use wood/twig-snap, also on the `snap` trigger).

风过树窍 —《庄子·齐物论》：「夫大块噫气，其名为风。是唯无作，作则万窍怒呺……激者、謞者、叱者、吸者、叫者、譹者、宎者、咬者，前者唱于而随者唱喁。泠风则小和，飘风则大和。」
