SoundPlayer

Vaadin component for playing mp3 sounds.

With SoundPlayer component you can play sounds in the users browser. Sounds must be in MP3 format. Component API features: load, stop, play, pause and a listener callback interface for player state changes. SoundPlayer is based on gwt-sound and SoundManager2 client-side implementations and requires Flash 8 plugin or newer to be installed. Also install gwt-sound.jar to your project.

Sample code

// Play a resource file
SoundPlayer player = new SoundPlayer();
mainWindow.addComponent(player);
player.play(new ClassResource("intro.mp3", this));

// Play a publicly available MP3
SoundPlayer player = new SoundPlayer();
mainWindow.addComponent(player);
player.play("http://www.a1sounddownload.com/freesounds5/alarmring.mp3");
