As a WordPress plugin, this is easy to install. Just search for ‘Audio Envelope’ from the WordPress Plugins directory. If you do this within your site, you can easily install and activate it from there.
The player will only display when there is audio on the page. This is by design. This player is meant to enhance existing audio.
To use it, add some audio to your page. You can do this by pasting a URL to some audio (like an mp3 file). You can also place this audio within an audio shortcode.
We think the best way to use this player is to create posts with audio in it. That way, you are managing your playlists by how you organize your content within your site.
For example, this page includes separate posts that make up this example. Each post includes audio. In our case, we have also added the audio to our excerpt.
