Use the laboratory responsibly.
Effective 16 October 2026
Educational purpose
Frequency Master provides interactive audio tools and educational editorial content. It does not provide medical diagnosis, treatment, professional engineering certification or a guarantee of any personal outcome.
Your listening setup
You are responsible for your playback equipment, listening level, environment and duration. Begin at low volume. Stop if listening causes discomfort, pain, ringing, dizziness or other unwanted effects.
No medical use
Do not use this site instead of qualified medical care or as a medical device. Do not delay treatment because of content or a frequency listed here. See the medical disclaimer.
Acceptable use
Do not attempt to disrupt the service, overload forms, introduce malicious content, impersonate another person or use the site to harm, harass or mislead. Automated submissions and attempts to bypass technical limits may be blocked.
Free member accounts
Creating a free feature account requires a unique nickname, email address and password. Surname and phone are optional. The public studio remains available without an account. You must confirm your email before member features become available. Keep your sign-in details private and contact us if you suspect someone else is using your account. Double modulation is included in the free member level. Registration also presents a separate, explicit Google Analytics choice; its purpose and controls are explained in the Privacy Notice. Analytics consent is not hidden inside these terms. Future paid features, if introduced, will have their own terms before purchase.
Feedback and contributions
You retain ownership of original ideas and text you submit. You give Frequency Master permission to read, analyse and use non-confidential suggestions to improve the project. Nothing is published with your identity automatically.
Accuracy and availability
We aim to cite reliable sources and correct material errors. Research changes, sources may be revised and browser or hardware behaviour varies. The service may change or become temporarily unavailable.
Intellectual property
The Frequency Master name, logo, interface, original text and generated sound designs are project materials unless a different source or licence is stated. Linked research remains the property of its respective authors and publishers.
Updates
Material changes will appear with a revised effective date. Continued use after a change means the updated terms apply from that date.
