WordPress 5.0 shipped in December with a group of blocks on board that bring built in functionality for users. During WordCamp US 18 Contributor Day, the design team evaluated potential blocks for future development.
The native WordPress Audio Player Block can be used to display a simple audio player for podcasts using a hosting platform like Soundcloud or Castos.
The player is added by selecting the Audio Block and entering a URL. The user has no control over the background color or the ability to add a podcast album cover.
Once inserted, the user can only set how the audio is played. No styling on the block is provided.
