Buzzing Fly

How it's made

Source

a single generic fly's 180-280 Hz wing strokes, with 12 phase-locked sine partials; strongest second through fourth partials describe the two asymmetric pressure strokes per cycle.

Body

harmonic amplitudes roll off above 1 kHz; broad 0.7-4 kHz wing-edge turbulence is softly modulated at twice the wing rate. No cavity ring, room reverb or unrelated ambient bed is added.

Envelope

continuous flight with smooth distance swells, random 0.7 Hz effort changes and 5 Hz micro-wander. The texture renderer supplies gentle entry and exit fades over an 8 s render.

Movement

a curved trajectory in metres drives inverse-distance gain, air-loss filtering and pan; its analytic radial velocity drives c/(c+v) Doppler at c=343 m/s, including approach and recession.

Variation

seeded path phase, wing tuning and drift prevent a mechanical cycle. Pitch controls wing rate; speed, span and clearance control flight; air controls the wing-edge noise balance.

Presets

close hover has small motion; circling has broad swells; darting makes rapid passes; distant flight loses upper harmonics and has slower, shallower movement.
