Spotlightr does support uploading audio files. We listened to your feedback and implemented an Audio Player option for them. It is very convenient if you wish to embed podcasts, audiobooks or songs on your site.

If you wish the player to look like an Audio Player, you can activate the audio player with basic controls. This is done in your Publish options.

Just activate the Audio player in your Publish options and then copy your embed code as you would a video.

Your audio player will look like this:

To change the colors of the player, simply apply a different theme to your Project.
