Stabilize your flow state. Use stereo headphones for binaural effect.
Binaural: sine carrier left=carrierHz, right=carrierHz+freqHz, gain = vol * 0.151875
Isochronic: 440Hz sine modulated by gainNode whose .gain = constSrc(0.5) + square(freqHz)*0.5
(freqHz floor 0.5), iso bus gain = vol * 0.10935
Ambient: pink (Voss-McCartney) or brown (RC-filtered white *3.5), 8s loop, gain = vol * 0.243
Overlay: pre-recorded loop fetched from /sounds/, gain = vol (direct)
Master: single GainNode after all buses, range 0\u20134\u00d7 (above 1 boosts beyond unity gain)
