How it's made
- Source
- an energy field gripping an object. Modelled as a low pull hum (detuned saw pairs at ~55 Hz plus a 110 Hz sine) and a mid "beam" tone near 520 Hz with weak 2nd and 3rd partials.
- Body
- the hum is low-passed (~220-680 Hz) so only a warm pull remains; the beam tone is low-passed with a gentle slope so no partial rings harshly; a band-passed pink-noise field adds the energy "air".
- Envelope
- continuous. The beam pitch rises and falls once per 8 s (+-4 %) as the object is dragged closer; a 2-10 Hz vibrato (the warble) deepens at the swell peak; a slow 0.25 Hz amplitude swell breathes.
- Modulation
- the detuned hum pair beats at 0.25 Hz (slow phasing); the noise band-pass sweeps in opposite directions in left and right channels (0.125 Hz), giving a phasing, widening stereo motion.
- Variation
- rng sets the beam pitch (+-3 %) and noise streams; presets change warble speed and depth, hum weight, brightness, phasing depth and beam pitch.
