What frequency is right for you?

Five questions about your goal, available time, whether you can wear headphones, your experience level, and your soundscape preference. Each answer narrows the recommendation toward a specific brainwave band (delta, theta, alpha, beta, or gamma), a delivery method (binaural, isochronic, monaural), a session length, and a layered soundscape. The result is a specific Hz target and an audio protocol you could run starting today.

It's informed by research — not a clinical diagnostic. Brainwave-band-to-goal mapping (delta for sleep, theta for meditation, alpha for flow, beta for focus, gamma for peak performance) reflects well-documented EEG correlations. The specific Hz values come from Arkhitec's preset library, which uses research-informed carriers. Individual response varies. Treat the quiz result as a starting point — try it, adjust based on how it feels.

We don't — the result shows even if you skip the email step. The email capture lets us save your recommended protocol to your Arkhitec early-access profile so it's ready in the app when it launches in 2026. Totally optional. No daily newsletter spam.

Yes. Retake it as often as you want — your goal changes, your context changes, your protocol should change too. A deep-work session at 10am and a wind-down at 10pm need completely different audio stacks. The quiz is designed for repeated use.

Pick the closest match — the recommendation engine still produces a reasonable starting point. If none of the goal options match, 'Concentrate on work' is a safe default for most alert states, and 'Meditate or relax' covers most rest states. You can always ignore the specific Hz and use Arkhitec's broader library to find the preset that feels right.
