How it's made
- Source
- two hard wing cases unlatch at 4 and 58 ms, followed by a softer hinge tick near 125 ms. Filtered 1-3 ms noise excites dry shell modes at 1.2, 2.3 and 4.1 kHz; no room is baked in.
- Body
- wing loading produces a 65-145 Hz buzz with six phase-related, falling-strength harmonics. Low-rate frequency wander and unequal stroke lobes roughen the buzz without a harsh saw edge.
- Layers
- stroke-modulated air noise spans 220 Hz to 3.6 kHz, with a broad 650 Hz body band. A short papery unfolding rustle bridges the shell clicks and the first powered strokes.
- Envelope
- wing motion starts 110-270 ms after unlatching and accelerates over about 180 ms. Lift peaks around 400 ms, then amplitude and high-frequency content recede to silence by 1.4 s.
- Variation
- seed changes shell timing, modal tuning and independent air turbulence; size changes shell pitch and wing rate. Presets cover light darting, heavy lumbering, hesitant and brisk takeoff.
