Meaning
Audio description conveys important visual information through additional spoken explanation when it is not already available from the main audio.
A practical example
A tutorial that silently changes a control may need a spoken account of what changed for someone who cannot see the screen.
What to check
Captions and description solve different access needs. Review the visual-only information rather than assuming a transcript alone makes the video understandable.
