Carrier Eighty

Holds a steady Alpha field at 10 Hz on a 84 Hz carrier.

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

Steady hold

The embedded pulse holds at 10 Hz in the Alpha range for a consistent rhythmic anchor. The authored target begins at the start and holds for 16 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.

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.

Design character

How this one is built

The carrier walked across its full usable span at a fixed beat, plus dedicated sessions for the two noise generators the catalog barely used. Reference material as much as listening material.

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 84 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.
