Audio Envelope pulls together disparate audio files listed in posts (typically in the excepts in posts) and provide a single player to control them. It also keeps track of the play point and can even continue to play the audio on subsequent pages that it is listed on.
This plugin requires at least one audio element. Audio can be added by inserting an audio file URL (ie. link to an mp3 file), or using the audio shortcode. All of the audio shortcodes render using either the HTML5 native audio player or the WordPress built-in media player (MediaElement.js). This plugin requires JavaScript.
