Focus session · M01
Gamma Work Sprint
Holds a steady High-Beta field at 38 Hz on a 317 Hz carrier.
Choose the full transition or begin at the advertised audio target. You can scrub and extend either path in the player.
Frequency journey
How the rhythmic pulse embedded in the sound changes from the opening moments to its destination.
The embedded pulse holds at 38 Hz in the High-Beta range for a consistent rhythmic anchor. The authored target begins at the start and holds for 12 min.
Sustained focus
For focused work, the rhythmic structure is meant to act as a stable backdrop rather than compete with the task.
Let the pattern settle
Deep-work blocks, reading, writing, and tasks that benefit from a consistent sound field. 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 isochronic 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.

How this one is built
Gamma-rate modulation for working blocks, held steady rather than ramped. Deliberately the shortest focus sessions in the catalog: fast modulation is the most fatiguing to sit with, so the design compensates with duration rather than depth.
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.
