Theta Gamma Coupling

Holds a steady 5.5 Hz Theta phase modulating a 41 Hz gamma layer.

Choose the full transition or begin at the advertised audio target. You can scrub and extend either path in the player.

Audio movement

Frequency journey

How the rhythmic pulse embedded in the sound changes from the opening moments to its destination.

Steady hold

The embedded pulse holds at 5.5 Hz in the Theta range for a consistent rhythmic anchor. The authored target begins at the start and holds for 20 min.

Why this journey

Long-form restorative listening

The restrained movement is designed for low-demand listening where continuity matters more than stimulation.

How to use it

Let the pattern settle

Low-demand routines, quiet breaks, and extended periods of unwinding. Start quietly and give the stable pattern a few minutes to recede behind what you are doing. You can also start directly at the target, scrub the journey, or extend the hold in the player.

Signal, not a scan. The line shows the modulation rate generated in the audio. It is not an EEG reading and does not promise that brain activity will follow the curve. Listening responses vary.

Choose the spatial feel

This session starts in phase-amplitude coupled mode. You can change how the beat is delivered without changing the frequency journey, or add a Shepard-Risset carrier drift for a continuously falling timbre.

Monaural
Two tones summed before they reach you, so the beat exists in the air rather than being built in your head. Smoother and less percussive than isochronic, and it works on speakers.
Binaural— needs stereo headphones
Two carriers a few hertz apart, one per ear. The beat is constructed in your brainstem, so it needs stereo headphones to exist at all.
Poly-rhythmic— needs stereo headphones
Each ear gets its own carrier and its own beat, related by the golden ratio rather than driven in lockstep. Needs headphones — on a speaker the two channels sum and the distinction is lost.

Design character

How this one is built

Phase-amplitude coupling walked across the gamma band rather than parked at 40 Hz. A slow phase governs a fast burst, and the coupling rate moves from 30 Hz to 80 Hz across the collection while the slow layer stays in theta and alpha.

Listen responsibly

Brainwavest is a wellness and relaxation tool, not a medical device. Session names and guidance describe design intent, not a promised physiological result. Binaural mode requires stereo headphones. Start quietly, and never use rhythmic audio while driving. Read the full safety notes.
