Hive Swarm Hum

How it's made

Source

asynchronous flying wing strokes, 155-340 Hz, modelled as 10-26 band-limited saw voices. Independent phase, tuning and 0.4-1.3 Hz flight drift smear the harmonics into a dense mid buzz.

Body

wing harmonics roll off above 1.1-3.7 kHz; a broad 650-1250 Hz turbulence band adds air. No fixed high-Q cavity or reverberation: this is an open, dry hive entrance rather than a box drone.

Envelope

continuous colony activity breathes over roughly 5-14 s; individual levels wander separately. A 180 ms opening and 900 ms closing taper prevent edge clicks at any requested duration.

Events

nearby insects swell and retreat over 1.4-3.1 s, at 0.12-0.65 arrivals/s, with a small falling pitch contour and stereo travel. Smooth envelopes keep flybys embedded in the colony bed.

Variation

named random streams vary phase, pitch spread, drift, level and flight position per insect. Density sets voice count, wing rate sets insect size, brightness sets harmonic reach and air balance.

Presets

sheltered low hum, busy hive entrance, bright wide airborne swarm and close passing traffic differ in population, wing rate, filtering, movement depth and foreground-to-background balance.
