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. Sometimes the audio context will be created with a sampleRate of 48000. If this happens and audio distorts you should re-create the context.

Members
-
baseLatency : number

-
The number of audio channels to use in playback.
Type:
- number
- Default Value:
-
- 32

Local reference to game.
Type:
-
mute : boolean
-
Gets or sets the muted state of the SoundManager. This effects all sounds in the game.
Type:
- boolean
-
muteOnPause : boolean
-
Set to true to have all sound muted when the Phaser game pauses (such as on loss of focus), or set to false to keep audio playing, regardless of the game pause state. You may need to do this should you wish to control audio muting via external DOM buttons or similar.
Type:
- boolean
- Default Value:
-
- true
- Source:
- src/sound/SoundManager.js line 128
-
noAudio : boolean
-
True if audio been disabled via the PhaserGlobal (useful if you need to use a 3rd party audio library) or the device doesn't support any audio.
Type:

-
onMute : Phaser.Signal
-
This signal is dispatched when the SoundManager is globally muted, either directly via game code or as a result of the game pausing.
Type:
-
onSoundDecode : Phaser.Signal

The event dispatched when a sound decodes (typically only for mp3 files)
Type:
-
onStateChange : Phaser.Signal
-
This signal is dispatched when the AudioContext state changes, only if using Web Audio.
Type:
-
onTouchUnlock : Phaser.Signal
-
This signal is dispatched when the SoundManager is touch-unlocked. If the device doesn't need touch-unlocking, the signal won't be dispatched.
Type:
-
onUnMute : Phaser.Signal
-
This signal is dispatched when the SoundManager is globally un-muted, either directly via game code or as a result of the game resuming from a pause.
Type:
-
onVolumeChange : Phaser.Signal
-
This signal is dispatched whenever the global volume changes. The new volume is passed as the only parameter to your callback.
Type:
-
touchLocked : boolean
-
true if the audio system is currently locked awaiting a touch event.
Type:
- boolean
-
<readonly> usingAudioTag : boolean
-
True the SoundManager and device are both using the Audio tag instead of Web Audio.
Type:
- boolean
-
<readonly> usingWebAudio : boolean
-
True the SoundManager and device are both using Web Audio.
Type:
- boolean
-
volume : number
-
Gets or sets the global volume of the SoundManager, a value between 0 and 1. The value given is clamped to the range 0 to 1.
Type:
- number
