01 — Binaural Engine

Dual-frequency precision

Set independent left and right ear frequencies with 0.1 Hz step controls. Your brain perceives the difference as a binaural beat that entrains brainwave activity.

Left ear carrier — cyan channel, 20–500 Hz
Right ear carrier — rose channel, 20–500 Hz
Beat frequency — Delta through Gamma bands
Sine, triangle, square, sawtooth waveforms
02 — Noise Generator

Mask distractions with colored noise

Four noise types — white, pink, brown, and blue — each generated with a 60-second buffer and 1-second overlap-add crossfade for seamless looping with zero audible seams.

White — equal energy across all frequencies
Pink — 1/f power spectrum, natural sounding
Brown — deep rumble, strong low-end
Blue — high-frequency emphasis
03 — Real-time Visualizer

See your sound

Live waveform and frequency spectrum displays driven by the Web Audio API's analyser nodes. Watch the binaural interaction in real-time as you adjust parameters.

04 — 10-Band Parametric EQ

Shape every frequency

Full parametric equalization from 31 Hz to 16 kHz with independent master, left, and right channel controls. Each band adjustable ±12 dB with 0.5 dB precision.

Master EQ — shapes the combined output
Left channel EQ — independent shaping
Right channel EQ — independent shaping
05 — Research-Backed Presets

Science-grounded starting points

Five presets built from published neuroscience research — each with calibrated carrier frequencies, noise configurations, and EQ curves optimized for their target brainwave state.

Deep Sleep — 2.5 Hz delta, brown noise, warm EQ
Relaxation — 6 Hz theta, pink noise
Calm Focus — 10 Hz alpha, pure tone
Concentration — 16 Hz beta, pure tone
Peak Attention — 40 Hz gamma, white noise
