Debut Audio is part of Debut, a set of baseline Drupal Features designed to work independently yet integrate seamlessly together.
Debut Audio provides users with the ability to post embedded audio files from either Archive.org or Podcast Alley. If an audio file already exists on one of these hosts, the user simply pastes in the URL when creating a new "Audio" content type. If the audio file has not already been uploaded, an additional step to upload the file needs to be done as well.
See the Debut Audio project page on drupal.org for more information.
