Our target
Frequency Master is designed with WCAG 2.2 Level AA in mind. It has not yet received an independent conformance audit, so we describe this as a target rather than a certification.
What is built in
- Keyboard access to generator controls, presets, navigation and forms.
- A skip link, semantic headings, labelled fields and visible focus states.
- Text alternatives for meaningful images and decorative images hidden from assistive technology.
- Layouts that reflow for narrow screens and browser zoom.
- Reduced-motion support through the operating-system preference.
- Status messages that do not rely on colour alone.
Audio-specific limits
The core experience contains sound, but every control and frequency value is available visually and programmatically. Audio is never started automatically. Some subjective properties of a sound cannot be represented fully in text.
Tell us about a barrier
Use the feedback form and select “Accessibility”. Include the page, control, browser and assistive technology when possible. We will prioritise reproducible barriers.
