Binaural Theta Drone

How it's made

Source

two continuous electronic sine carriers, isolated to left and right headphones; the right carrier is 4-7 Hz above the left. Default 198/204 Hz gives a 6 Hz interaural frequency difference.

Body

fundamentals at 140-280 Hz provide warm low mids. A second harmonic at 0-8% amplitude adds optional body without noise, saturation, bright partials or crossfeed between the two ears.

Layers

each ear has its own fundamental and phase-locked second harmonic; there is no mono beat oscillator. Headphones preserve the frequency separation; mono playback gives ordinary beating.

Envelope

uninterrupted sustain with at most 2% common amplitude breathing per 16 s; harmonic gain moves by 10% of its already small level over the same period. No repeated attacks or release gaps.

Loop

default carriers, offsets, harmonics and modulation complete whole cycles in 16 s. The engine crossfades arbitrary parameter settings and durations; shared modulation never changes the beat rate.

Variation

carrier pitch, interaural offset, harmonic warmth and breathing are independent controls. Four presets cover low 4 Hz, pure 6 Hz, warm 5 Hz and upper 7 Hz pairs. No random pitch wander.
