Secondary or alternate audio tracks are commonly used for this purpose.</div>

Audio descriptions (also called "video descriptions", "descriptive narration", and "described videos") add descriptive information of important visual information needed to understand the video content, including text displayed in the video. Where the main audio track of the video fully describes important visual information, audio descriptions would not be needed at all as the requirement would already be met. When audio descriptions are needed, one way to implement them is by providing a second audio track for the audio-video media.</div>
