Use headphones for binaural beats. Not recommended for people with epilepsy or photosensitive conditions. Do not use while driving or operating machinery.
What is Liminal?
Liminal is a brainwave entrainment tool. By listening through headphones to specific audio patterns, it gently encourages your brain toward particular mental states — deep rest, meditation, creative flow, or sharp focus.
How binaural beats work
Play 200 Hz in your left ear and 210 Hz in your right, and your brain perceives the 10 Hz difference as a slow pulse — and gradually synchronises to it. This is called the frequency-following response. Different beat frequencies correspond to different brain states: delta for deep sleep, theta for hypnagogic meditation, alpha for calm alertness, beta for active thinking. Headphones are essential — the stereo separation between ears is what creates the effect.
What you can do
Mix up to six simultaneous audio layers: binaural beats, isochronic pulses (work without headphones), coloured noise, a procedural ocean soundscape, an ambient file player (load any audio), and sacred-frequency tones with configurable ADSR envelopes. Each layer has its own volume and pan. Use the brainwave presets to jump to common targets, or build a custom Session Sequence that ramps frequencies through any arc you design, with timed tone cues firing at precise moments. Share any sequence instantly with the ⧉ Link button — the full program is compressed into a URL you can paste anywhere.
Try: Chakra Reset ✦
A 21-minute guided session divided into seven 3-minute segments — one for each chakra. The binaural beat traces a bell curve: opening at 10 Hz mid-alpha, descending through the Schumann resonance (7.83 Hz) into 6.5 Hz theta at the heart centre, then rising back to alpha by the crown. Each segment fires the corresponding Solfeggio frequency tone at the start of its hold phase. The heart segment adds 432 Hz (universal harmony). The session opens with a long Om bell (111 Hz) and closes with an extended 963 Hz crown tone followed by a final Om. Ocean is enabled throughout. Find the Chakra Reset button in the Brainwave Presets section.

The Monroe Institute has pioneered research into altered states of consciousness through audio guidance since the 1970s, including the Hemi-Sync® binaural beat technology that inspired much of this field. Their work remains the most rigorous scientific reference for this kind of practice.
