Frontier session · G16
Three Stage Descent
A staged journey: 12 Hz → 6 Hz → 1.5 Hz, over 20 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 moves through 12 Hz → 6 Hz → 1.5 Hz, creating distinct phases instead of one straight ramp. The authored target begins at 20 min and holds for 14 min.
Exploratory listening
These sessions foreground the engine’s less conventional behaviors so you can hear how the signal design changes the experience.
Give the transition room
Comparing unusual trajectories, delivery modes, envelopes, and modulation techniques. Start quietly and let the ramp unfold instead of judging the session in its first minute. The target then holds for 14 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
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 runs on a 128 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.
