With the announcement of the new ADA rules implementing WCAG 2.1 requirements for audio-assisted descriptions for streaming video (see https://www.w3.org/TR/WCAG21/#audio-description-prerecorded), we would like Alma Digital to accept an additional audio track in its film viewer that would play simultaneously with the video. While we can currently add an additional file to the Alma Digital representation, it cannot play simultaneously with the video.
