Quick guide
Pick a beat frequency that matches your goal — delta (0.5–4 Hz) for sleep, theta (4–8 Hz) for deep meditation, alpha (8–13 Hz) for calm focus, beta (13–30 Hz) for alert work, gamma (30–40 Hz) for intensity of attention. The carrier is just the pitch that carries it; 100–400 Hz is comfortable for most people. Sessions of 15–30 minutes are typical. Don't use entrainment audio while driving, and if you have epilepsy or a seizure disorder, talk to your clinician first.
