Making Audio Content Accessible

You’re most likely here because you need to make sure your web audio content is accessible to people with disabilities.

You might have a specific problem, like:

  • how to make an audio player keyboard accessible so it can be used by assistive technology
  • how to provide audio content in alternative formats
  • how to avoid keyboard traps
  • whether to start audio automatically
  • what controls need to be provided

Perhaps you need a comprehensive list of likely issues with audio web accessibility – and how to address them. Or maybe you just want to ask a direct question and get a clear, expert response.

You’re in the right place.

OzWiki will tell you what you need to know to make the web audio content accessible. The Audio section details 18 accessibility problems and how to address them, demonstrating compliance with 15 WCAG Level A success criteria and three Level AA success criteria.

WCAG SC 2.1.1: Keyboard

All functionality of the content is operable through a keyboard interface without requiring specific timings for individual keystrokes, except where the underlying function requires input that depends on the path of the user's movement and not just the endpoints.

Note 1: This exception relates to the underlying function, not the input technique. For example, if using handwriting to enter text, the input technique (handwriting) requires path-dependent input but the underlying function (text input) does not.

Note 2: This does not forbid and should not discourage providing mouse input or other input methods in addition to keyboard operation.
