Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.

How it's made
Source
a generic large insect holds position with 24–50 Hz wing strokes. Smooth asymmetric pressure pulses gate low air turbulence; a weaker delayed return stroke keeps each cycle from sounding chopped.
Body
broad 130–650 Hz turbulence supports quiet second, third and fifth wingbeat harmonics, modelling periodic aerodynamic loading rather than a pitched call. No narrow high-Q resonances are used.
Membrane
independent noise in broad 0.7–3 kHz bands follows the downstroke, with a softer 3–5 kHz edge; these short, rounded noise swells give dry papery wings without isolated clicks or brittle hiss.
Envelope
continuous 12 s hover, breathing over 2–6 s; stroke shape is smooth at millisecond scale. The texture renderer supplies the 50 ms entry and 750 ms exit fades. No baked room or reverb.
Motion
seeded slow wander changes wingbeat by up to 3.5%, brightness, level and pan together; independent faster flutter varies membrane strength. Narrow stereo represents one nearby source, not a swarm.
Variation
presets offer slow heavy strokes, close dry paper, a rounded soft whir and a tense fast hover; controls set stroke rate, membrane balance, whir balance, spectral openness and positional instability.
