Problem: delivering a narration track that describes on-screen action for blind or low-vision viewers on YouTube. Conditions: Advanced features access; YouTube Studio on computer > Languages > video > language. Method: the language's original or dubbed audio track must be uploaded first; then, next to Descriptive audio, Add > Select file > Publish. The file must be a supported audio-only format and roughly the same length as the video. To replace a track, delete the descriptive audio for that language and upload again. YouTube describes the track as narration placed in natural pauses in the audio. Failure modes: no descriptive slot appears if the base-language audio track is missing; an audio file that is much shorter or longer than the video. Limitations: this page gives no writing guidance (tense, density, extended description), which earlier candidates cover from ACB/DCMP/Netflix/Ofcom; supported file types are not listed inline; availability is gated.
