Calm session · 0317
Stress-Line Downshift
Moves from SMR to Infra-Low — 15 Hz easing to 0.3 Hz over 11 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 15 Hz (SMR) to 0.3 Hz (Infra-Low), so its rhythmic emphasis becomes less rapid over the ramp. The authored target begins at 11 min and holds for 17 min.
A quieter listening context
For a calm routine, the signal is designed to feel less urgent and easier to let recede from attention.
Give the transition room
Downshifting after a busy period, gentle breaks, and low-stimulation personal time. Start quietly and let the ramp unfold instead of judging the session in its first minute. The target then holds for 17 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
Infra-low and slow delta targets with the deepest modulation and the slowest spatial orbits available. Ramps are long by design; nothing here arrives quickly.
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 runs on a 125 Hz carrier, below what a phone or laptop speaker reproduces — use headphones or it will sound almost silent. Start quietly, and never use rhythmic audio while driving.
