**MELEK Sleep & Focus** is the brainwave-entrainment surface of the ecosystem, published at sleep.melek.salon. It generates **binaural beats**, **isochronic tones** and a **40 Hz gamma preset** live in the browser — nothing is pre-recorded or downloaded.

## How it works

- **Binaural beats** — two slightly different tones, one in each ear, whose difference is the entrainment frequency. Headphones are required for these.
- **Isochronic tones** — a single tone gated on and off at the pulse rate; these work on speakers.
- **40 Hz gamma preset** — the gamma-band preset at 40 Hz, the frequency studied in the Gamma Entrainment research line.

Presets cover the classic EEG bands; gamma is the 40 Hz preset. The tone is synthesized in the browser from a carrier frequency and a beat frequency, so a session can run without streaming anything.

## Honesty note

The surface describes what each band is, not what it will do for a given person. The blurbs state the frequency and the type; they do not promise a clinical outcome. For the research context, see Gamma Entrainment and Display Refresh and Flicker Delivery.
