createAudioContext(game)
Focus
Focus

Description:

Method responsible for instantiating and returning AudioContext instance. If an instance of an AudioContext class was provided through the game config, that instance will be returned instead. This can come in handy if you are reloading a Phaser game on a page that never properly refreshes (such as in an SPA project) and you want to reuse already instantiated AudioContext.

Parameters:

name type description

Reference to the current game instance.

Returns:
Description:

The AudioContext instance to be used for playback.

Type:
  • AudioContext

decodeAudio([audioKey], [audioData])
Focus
Focus

Description:

Decode audio data into a format ready for playback via Web Audio.

The audio data can be a base64 encoded string, an audio media-type data uri, or an ArrayBuffer instance.

The audioKey is the key that will be used to save the decoded audio to the audio cache.

Instead of passing a single entry you can instead pass an array of Phaser.Types.Sound.DecodeAudioConfig objects as the first and only argument.

Decoding is an async process, so be sure to listen for the events to know when decoding has completed.

Once the audio has decoded it can be added to the Sound Manager or played via its key.

Parameters:

name type arguments description
audioKey string | Array.<Phaser.Types.Sound.DecodeAudioConfig> <optional>

The string-based key to be used to reference the decoded audio in the audio cache, or an array of audio config objects.

audioData ArrayBuffer | string <optional>
