How it's made
- Source
- a steady air jet locks to a slide whistle's pipe mode; a sine-dominant voice carries the tone.
- Body
- shortening effective pipe length raises f=c/(4L), from 520 to 1900 Hz by default; weak 2nd/3rd partials (about -32/-38 dB) add edge colour. Band-passed turbulence tracks the moving fundamental.
- Layers
- a quiet 650-5200 Hz air bed and Q=5 pipe-filtered breath sit beneath the tonal core; no reverb.
- Envelope
- air enters over 18 ms, tone locks over 35 ms, pressure swells slightly, then releases over the last 95 ms. Default excitation ends at 700 ms, leaving about 100 ms of silent render tail.
- Modulation
- a gentle terminal vibrato and sub-percent slow pressure wander avoid a sterile sweep.
- Variation
- seeded tuning varies +/-0.6 percent; length, register, rise span, air and wobble set the gesture. Presets give a quick high double-take, low broad lift, airy reveal and lingering wobbly surprise.
