Split Field Stillness

Holds a steady Theta field at 5.5 Hz on a 136.1 Hz carrier.

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

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 33 min.

Why this journey

Exploratory listening

These sessions foreground the engine’s less conventional behaviors so you can hear how the signal design changes the experience.

How to use it

Let the pattern settle

Comparing unusual trajectories, delivery modes, envelopes, and modulation techniques. 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.

Available in the player

Choose the spatial feel

This session starts in poly-rhythmic 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.

Design character

How this one is built

The collection that exercises the parts of the engine nothing else reaches. Native binaural, monaural and poly-rhythmic sessions rather than isochronic ones with alternatives, alongside multi-waypoint beat curves and the only duty cycles in the catalog that are not 50%. Organized by technique rather than by outcome, which is why the bands range from 1.5 Hz to 22 Hz inside one collection.

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. This session’s poly-rhythmic delivery requires stereo headphones. Start quietly, and never use rhythmic audio while driving. Read the full safety notes.
