Accessibility Statement

SKR4CH is committed to making the SKR4CH Waveform Designer as usable as possible for as many people as possible. We aim for clear layouts, readable text, and keyboard-accessible controls wherever practical.

What this site is

SKR4CH is a browser-based waveform design tool. The main interface is an interactive canvas with multiple control panels, sliders, and buttons. The core editing experience is highly visual and interaction-heavy, which means some accessibility limitations currently exist.

Keyboard access

Where supported by the browser, key parts of the interface can be used with a keyboard:

  • Buttons and controls can be reached using Tab / Shift+Tab and activated with Enter/Space.
  • The canvas is focusable, and the site supports keyboard panning (left/right arrow keys) when the canvas is in use.
  • Sliders and other controls include keyboard support where possible.

Important limitations

Some parts of the Waveform Designer are not fully accessible at this time:

  • Canvas editing requires a mouse or pointer device. Drawing, inserting nodes, dragging nodes, and shaping curves depend on pointer interactions.
  • Zooming and precision editing rely heavily on mouse wheel/trackpad and fine pointer movement.
  • The waveform visuals (drawn/output/harmonics) are not fully described to screen readers, because they are rendered as graphics.
  • Some interaction feedback is provided visually (for example, highlights and waveform previews), which may not be accessible to all users.

Screen readers and ARIA

We use semantic HTML and ARIA attributes where appropriate to label interactive elements and dialogs. However, because the main editor is canvas-based, screen readers may not be able to interpret the waveform display or the detailed editing state.

Visual design and readability

We aim for high contrast and consistent sizing across pages. If any text, controls, or focus indicators are difficult to see, we want to know so we can improve it.

Known compatibility notes

Accessibility support can vary depending on your browser, operating system, and device. If you are using a mobile device or a non-pointer input method, you may experience limitations with the editor.

Feedback and contact

If you experience an accessibility barrier, please contact us at skr4ch@gmail.com and include:

  • the page you were using (for example: “Waveform Designer”, “Download menu”, etc.)
  • your device and operating system
  • your browser (Chrome, Firefox, Safari, etc.)
  • what you expected to happen, and what actually happened

We use this feedback to prioritize accessibility improvements.

Updates

We may update this statement as the site evolves and accessibility support improves.
