Since 4.0

The ace:audioPlayer component renders an HTML5 <audio> element.

See the ICEfaces Showcase Live Demo of this component, complete with source code.

Getting Started

To start using the AudioPlayer component it is enough to specify an audio resource in the value attribute and the MIME type of such resource in the 'type' attribute.

<ace:audioPlayer id="audioPlayer"
		type="audio/mpeg" />


TagLib Documentation
This section covers attributes involved in the typical use-cases for this component. For reference, the complete taglib documentation for this component is available here.

The value attribute specifies an audio resource, which can either be a string representing a relative path to the audio file in the server, or a byte array that contains the encoded media, or a JSF resource.

The controls flag will render the playback controls if set to true.

The loop flag will cause the player to keep playing the media repeatedly.

The autoplay flag will cause the media to be played at the moment the component is loaded on the page.

If muted is set to true, the audio will be muted. Note that in many OS's, this attribute is not dynamic, meaning that it's not possible to change it programmatically. Once it is set to a certain value in the markup, it cannot be changed again at the markup level. However, the user will still be able to change it using the native player controls (if provided).

The type attribute is used to specify the MIME type of the media file.
