Audio object

The Audio object holds MP3s.

Note: Although SmartBuilder will play any .MP3 format, it is beneficial to encode your .MP3s at a size that is optimal for online viewing.  We suggest:

  • Layer-3, 44100Hz
  • 128 Kbps, mono

You can choose whether or not to preload your audio.

You can choose whether the audio starts to play when it is shown or not. Even with Autoplay checked, if an audio object is hidden, or placed in a non-visible Display, it will not play until it is shown.  Uncheck autoplay only if you want to start the audio with an action, or a user's click.

User tip: Putting an Audio object in a feedback display with {Autoplay = on} and {Display Controller = off} is a great way to add audio without having to add new actions.

You can choose whether the controller is displayed or not.

You can also choose which type of controller you wish to display.

You can also determine whether the audio loops or not.  A loop count of 0 will play through the audio 1 time and then stop.

You can set the volume for this specific Audio object.

Note: You can set the audio for the entire lesson dynamically using the Page Controller > setAudioVolume response method.  You can also use the volume controller widget to further expose this control to the end learner.
