Phaser Class: SoundManager

new SoundManager(game)

The Sound Manager is responsible for playing back audio via either the Legacy HTML Audio tag or via Web Audio if the browser supports it. Note: On Firefox 25+ on Linux if you have media.gstreamer disabled in about:config then it cannot play back mp3 or m4a files. The audio file type and the encoding of those files are extremely important. Not all browsers can play all audio formats. There is a good guide to what's supported here: http://hpr.dogphilosophy.net/test/

If you are reloading a Phaser Game on a page that never properly refreshes (such as in an AngularJS project) then you will quickly run out of AudioContext nodes. If this is the case create a global var called PhaserGlobal on the window object before creating the game. The active AudioContext will then be saved to window.PhaserGlobal.audioContext when the Phaser game is destroyed, and re-used when it starts again.

Mobile warning: There are some mobile devices (certain iPad 2 and iPad Mini revisions) that cannot play 48000 Hz audio. When they try to play the audio becomes extremely distorted and buzzes, eventually crashing the sound system. The solution is to use a lower encoding rate such as 44100 Hz.

Parameters:

Name	Type	Description
`game`	Phaser.Game	Reference to the current game instance.

`key`	string			Asset key for the sound.
`volume`	number	<optional>	1	Default value for the volume.
`loop`	boolean	<optional>	false	Whether or not the sound will loop.

setDecodedCallback(files, callback, callbackContext)

This method allows you to give the SoundManager a list of Sound files, or keys, and a callback. Once all of the Sound files have finished decoding the callback will be invoked. The amount of time spent decoding depends on the codec used and file size. If all of the files given have already decoded the callback is triggered immediately.

Parameters:

Name	Type	Description
`files`	string \| array	An array containing either Phaser.Sound objects or their key strings as found in the Phaser.Cache.
