audio-and-sound

To add background music and sound effects in Phaser 4, use this.load.audio in the preload method to load audio files, then manage playback via this.sound.play or this.sound.add in your scene to trigger sound effects and start looping background music.

Spatial audio in Phaser uses the Web Audio backend to configure listener position and sound source tracking. You can enable spatial audio by adjusting panning and tracking source positions relative to the listener during runtime playback.

You can control audio playback during gameplay by creating persistent sound instances via this.sound.add. These instances support adjusting volume, mute, rate, detune, and executing stop, pause, and resume commands as gameplay changes.

Browser autoplay policies often block audio from playing automatically without user interaction. Phaser handles this by unlocking the Web Audio or HTML5 audio backend, requiring a user input event to initialize the SoundManager before playback starts.

Phaser 4 supports both Web Audio and HTML5 audio backends through its unified SoundManager. This allows you to handle cross-browser differences and configure format fallbacks for consistent audio loading and playback.

The best way to handle cross-browser audio fallbacks in Phaser is to load multiple audio formats using this.load.audio. Phaser's SoundManager automatically selects the compatible WebAudio or HTML5 backend to ensure consistent playback.
