With the MP3 Player component, authors can allow a user to play an audio file embedded on the page using a simple player with quick load times and styled to match UC websites.
First, you'll need to upload your MP3 file(s) to DAM. If you're not familiar with this process, visit the Uploading Assets page first. These files should ideally be placed in the 'media' folder underneath your site's DAM folder. Once you've done this, open up the page you'd like to add the MP3 to in Author Mode.
The MP3 Player component can be found in the Multimedia section of the sidekick. Click and drag it onto your page, and then refresh. At this point you should see the player on the page; either double-click or right-click to open up the Edit Dialog.
