Returns:

The new sound instance.

Type
Phaser.Sound.WebAudioSound

addAudioSprite(key [, config])

Adds a new audio sprite sound into the sound manager. Audio Sprites are a combination of audio files and a JSON configuration. The JSON follows the format of that created by https://github.com/tonistiigi/audiosprite

Parameters:
Name Type Argument Description
key string

Asset key for the sound.

config Phaser.Types.Sound.SoundConfig <optional>

An optional config object containing default sound settings.

Since: 3.0.0
Inherited From:
Source: src/sound/BaseSoundManager.js (Line 184)

addListener(event, fn [, context])

Add a listener for a given event.

Parameters:
Name Type Argument Default Description
event string | symbol

The event name.

fn function

The listener function.

context * <optional>
this

The context to invoke the listener with.

Since: 3.0.0

decodeAudio( [audioKey] [, audioData])

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 Argument Description
audioKey Array.<Phaser.Types.Sound.DecodeAudioConfig> | string <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>

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