The Audio component is used to add an audio player to accompany the text on the page. We support uploading an mp3 file or linking to audio hosted on Panopto. The Add New Media and Add Existing Media dialogs work the same as with the Image component.
Rather than a caption, the Audio component has a Blurb field which allows you to add a few sentences to introduce the audio clip. There is also a field for a Transcript of the audio, for people who are not able to listen. This should always be included to meet our Web Accessibility best practice.
