How it's made
- Source
- buckling tymbals excite noise at 150-500 pulses/s, with rounded pulse edges and rate wander.
- Body
- each abdomen colours the pulses with a 4-8 kHz band (Q 3.2-5) and a weaker upper shoulder. Noise excitation, modest Q and an 11 kHz low-pass keep the piercing buzz free of pure whistles.
- Envelope
- independent 4-10 s phrases rise smoothly, crest and subside, with a quiet sustained floor. Offset phases and slow random amplitude motion prevent synchronized, mechanical chorus breathing.
- Layers
- 3-10 positioned individuals overlap above a diffuse stereo bed of distant resonant insects. Faster tymbal modulation remains independent of the much slower calling phrases.
- Variation
- seeded streams vary tuning by 12%, pulse rate by 18%, phrase speed, phase, level and pan. Density selects individuals; pitch, pulse rate, phrase length and distance change useful perspectives.
- Space
- distance reduces high-frequency detail and foreground level without adding baked-in reverb.
