Focus session · 0509
High-Pressure Composure
Moves from High-Beta to Alpha — 22 Hz easing to 10 Hz over 2 minutes.
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 gradually slows from 22 Hz (High-Beta) to 10 Hz (Alpha), so its rhythmic emphasis becomes less rapid over the ramp. The authored target begins at 2 min and holds for 16 min.
Sustained focus
For focused work, the rhythmic structure is meant to act as a stable backdrop rather than compete with the task.
Give the transition room
Deep-work blocks, reading, writing, and tasks that benefit from a consistent sound field. Start quietly and let the ramp unfold instead of judging the session in its first minute. The target then holds for 16 min by design. 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
Mid-beta targets with an SMR floor. Carriers are chosen to stay clear of the frequency range most speech and alerts occupy.
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.
