    detune: number

    Global detuning of all sounds in cents. The range of the value is -1200 to 1200, but we recommend setting it to 50.

    game: Game

    Local reference to game.

    gameLostFocus: boolean

    Flag used to track if the game has lost focus.

    jsonCache: BaseCache

    Local reference to the JSON Cache, as used by Audio Sprites.

    listenerPosition: Math.Vector2

    The Spatial Audio listener position.

    Only available with WebAudio.

    You can modify the x/y properties of this Vec2 directly to adjust the listener position within the game world.

    locked: boolean

    Mobile devices require sounds to be triggered from an explicit user action, such as a tap, before any sound can be loaded/played on a web page. Set to true if the audio system is currently locked awaiting user interaction.

    mute: boolean

    Global mute setting.

    pauseOnBlur: boolean

    Flag indicating if sounds should be paused when game looses focus, for instance when user switches to another tab/program/app.

    rate: number

    Global playback rate at which all the sounds will be played. Value of 1.0 plays the audio at full speed, 0.5 plays the audio at half speed and 2.0 doubles the audio's playback speed.

    volume: number

    Global volume setting.

      If you call this method with no parameters it will default to the center-point of the game canvas. Depending on the type of game you're making, you may need to call this method constantly to reset the listener position as the camera scrolls.

      • Optionalx: number

        The x position of the Spatial Audio listener.

      • Optionaly: number

        The y position of the Spatial Audio listener.
