How it's made

Source
one sustained sinusoidal pressure wave, nominally 440 Hz; no noise or added harmonics.
Body
continuous log-frequency portamento rises, falls below its origin, then turns upward again. A 0.45-1.1 Hz vibrato bends pitch by 0.6-2.8 semitones; slow drift adds at most 0.07 semitone.
Envelope
a 240 ms rounded emergence, a gently breathing body, and a 1.1 s withdrawal ending at 3.3 s.
Space
a quiet 43 ms reflection and low-wet room diffusion leave a thin, damped trail, not a second voice. The direct tone stays central; only the reflection is offset. A final fade clears the tail by 4.05 s.
Variation
seeded vibrato phase and drift keep the gesture organic without changing its identity. Pitch, glide span, vibrato rate/depth and room amount distinguish low, high, close and restless presets.
