WCAG 1.4.2 Audio Control
This page demonstrates how to meet the WCAG 2.1 criterion 1.4.2: Audio Control (Level A).
- Goal: If audio plays automatically for more than 3 seconds, users must have a mechanism to pause, stop, or control the volume independently of the system volume.
- What to do: Provide accessible controls for any auto-playing audio.
- Why it's important: Unexpected or uncontrollable audio can interfere with screen readers and make content inaccessible.
What to Avoid: Inaccessible Audio
Below is an auto-playing audio clip without any controls. Users cannot pause, stop, or adjust the volume. This fails WCAG 1.4.2.
Why this fails: There is no way for users to pause, stop, or control the audio. This can interfere with screen readers and create a poor user experience.
Example: Accessible Audio Control
Below is an audio clip that plays automatically. Use the provided controls to pause, stop, or adjust the volume.

Why this works: The audio element provides built-in controls, allowing users to pause, stop, or adjust the volume as needed.
Best Practices Summary
- Avoid auto-playing audio whenever possible
- Always provide accessible controls for audio
- Ensure controls are keyboard accessible
- Test with screen readers to verify usability
