stress relief Alpha band
Instant Calm
10 Hz beat · 432 Hz carrier · 3 phases · 10 min · beginner
The shortest session here, and the one to start with if you have not tried structured audio before. Ten minutes, ten hertz, nothing complicated.
The beat and carrier in the heading are the main phase — the part of the session it was built around. They are not what plays for the whole length. Every programme here opens in the alpha band, wherever it is going afterwards, and most come back up before they finish. The full phase plan is on this page, and it is the honest picture of what you would actually hear.
Hear it
Thirty seconds rendered at the parameters of the phase named above — not an excerpt cut from the paid file, so the full deliverable never loads on a public page. The figures the player draws are computed from the audio or from plate mathematics; none of them is a measurement of your hearing.
What this actually is
Ten hertz sits in the middle of the alpha band — the most-studied rate in the category, and the one most consumer products build around. It is a distinct, steady flutter that most people notice within the first minute.
Alpha runs from eight to thirteen hertz. It is the most-studied band in the consumer category and the one people usually mean when they say brainwave audio, which also makes it the band with the most overstated marketing around it.
The full phase plan
Three phases in ten minutes, and the only programme in the catalogue that stays inside one band from start to finish. Eight hertz for three minutes, ten for five, ten and a half for the last two — it drifts slightly upward rather than settling down, which is what makes it usable in the middle of a day.
| Phase | Role | When | Beat | Band | Carrier |
|---|---|---|---|---|---|
| Emergency Calm | induction | 0–3 min | 8 Hz | Alpha | 396 Hz |
| Stabilization | main | 3–8 min | 10 Hz | Alpha | 432 Hz |
| Centered Return | emergence | 8–10 min | 10.5 Hz | Alpha | 528 Hz |
Where the 432 Hz carrier comes from
Alternative concert pitch. An alternative tuning for the A above middle C. Verdi argued for a pitch near this value in the 1880s, and an Italian decree of the period adopted it.
The historical argument about orchestral pitch is real and documented. The modern claims that 432 hertz differs from 440 in its effect on a listener are not established, and we make none.
The carrier is the pitch you actually hear. The binaural difference — the part that makes this a structured session rather than a tone — lives between the two channels and is set by the beat, not by the carrier. Choosing one carrier over another is a tonal choice, the way picking a key is a tonal choice. It is not a functional one.
What this is
Instant refers to the length, not to a result. Ten minutes at ten hertz — the most-studied rate in the category — drifting slightly upward rather than settling down, which is what makes it usable in the middle of a day.
Who it is for
A first try, or a break in the middle of something. It is also the excerpt the preview player uses, so you can hear this one before deciding anything.
This is one of the starting points a session is built from, published in full — phase plan, parameters and an excerpt you can hear — so you can see what you are buying before you buy it. What arrives is rendered to the plan on this page, in three formats, at one price.
