Frontier session · S19
Wide Gate Study
Holds a steady Theta field at 5 Hz on a 216 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 5 Hz in the Theta range for a consistent rhythmic anchor. The authored target begins at the start and holds for 23 min.
Exploratory listening
These sessions foreground the engine’s less conventional behaviors so you can hear how the signal design changes the experience.
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.
- 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.
- Poly-rhythmic— needs stereo headphones
- Each ear gets its own carrier and its own beat, related by the golden ratio rather than driven in lockstep. Needs headphones — on a speaker the two channels sum and the distinction is lost.

How this one is built
A deliberate study of two parameters the rest of the catalog holds constant. Carrier and beat are fixed at 216 Hz and a single rate so that envelope shape and duty cycle are the only things changing — from a tenth-duty gate to nine-tenths, and across all six envelope shapes.
