How it's made
Source
a soft, breathy sine tone whose pitch sags downward, like a small resonator losing its drive. Two sine voices detuned by about 0.4 % beat slowly and give the tone a warm, living body.
Body
a fundamental at 500–700 Hz glides down 4–7 semitones; a quiet octave partial (2×) glides with it and is low-passed along the same curve, so the sound darkens as it falls and the tail ends as a pure sine.
Envelope
a 12 ms raised-cosine style onset (no click), a gentle hold of about 60 ms, then a long exponential-like fade to silence over 0.35–0.5 s. The glide is fast at first and settles, like a decaying spring.
Variation
`rng` detunes the two voices by a fraction of a percent; `pitch`, `fall` and `length` set the register, the size of the drop and the duration; `softness` sets the octave partial and the low-pass height.
