80 hz sine — sub-bass foundation. Amplitude oscillates ±0.10 at 0.064 hz; pitch drifts ±10% over a ~3 min cycle.

124 hz sine — upper bass warmth. Amplitude and pitch independently modulated with offset phases.

248 hz sine — gentle harmonic partial of the 124 hz layer, kept low in the mix.

sawtooth 201 hz — mid-range texture. Fed through two chorus voices and a feedback delay (340 ms, 0.45 feedback). Pitch steps randomly every 6–12 s.

sawtooth 301.5 hz — a fifth above, adding harmonic complexity. Independent pitch-step timing.

brown noise — white noise through a leaky integrator (α = 0.98), scaled ×3.5. Gain breathes slowly.

dub bassline — 16-step sequencer at 41 bpm. Sine through a 280 hz lowpass (Q=2), percussive envelope, into a dub echo chain: 8th-note delay, 0.62 feedback through a darkening 900 hz lowpass. Fades in over 60 s.
