    "system_prompt": "name audio-and-sound description Use this skill when adding audio or sound to a Phaser 4 game. Covers loading audio, playing sounds, music, volume, spatial audio, Web Audio API, and SoundManager. Triggers on: sound, audio, music, volume, mute. Audio and Sound Phaser provides a unified Sound system via this.sound (a SoundManager) that abstracts over Web Audio API and HTML5 Audio. It handles loading, playback, volume, panning, looping, markers, audio sprites, spatial audio, and browser autoplay-policy unlocking. Key source paths: src/sound/BaseSoundManager.js , src/sound/BaseSound.js , src/sound/webaudio/ , src/sound/html5/ , src/sound/SoundManagerCreator.js , src/sound/events/ , src/sound/typedefs/ Related skills: ../loading-assets/SKILL.md, ../game-setup-and-config/SKILL.md Quick Start class GameScene extends Phaser.Scene { preload ( ) { this . load . audio ( 'bgm' , 'assets/music.mp3' ); this . load . audio ( 'coin' , [ 'assets/coin.ogg' , 'assets/coin.mp3' ]); } create ( ) { // Fire-and-forget (auto-destroys when complete) this . sound . play ( 'coin' ); // Retained reference for ongoing control this . music = this . sound . add ( 'bgm' , { loop : true , volume : 0.5 }); this . music . play (); } } Assets loaded via this.load.audio() in preload() are ready by the time create() runs. Provide an array of URLs for cross-browser format fallback. Core Concepts WebAudio vs HTML5 Audio Phaser auto-selects the best backend via SoundManagerCreator.create() : If config.audio.noAudio is true, or the device supports neither Web Audio nor HTML5 Audio, a NoAudioSoundManager is created (all calls are no-ops). If the device supports Web Audio and config.audio.disableWebAudio is not true, a WebAudioSoundManager is created (preferred). Otherwise, an HTML5AudioSoundManager is created as fallback. WebAudio advantages: precise timing, gapless looping, stereo panning ( StereoPannerNode ), spatial audio ( PannerNode ), per-sound gain nodes, decodeAudio() for runtime decoding. HTML5 Audio limitations: no spatial audio, no real stereo panning (pan fires events but no audible effect), less precise looping, requires instances count at load time for simultaneous playback. Force HTML5 or disable audio via game config: audio: { disableWebAudio: true } or audio: { noAudio: true } . Pass audio: { context: existingAudioContext } to reuse a WebAudio context in SPAs. The SoundManager ( this.sound ) Accessed via this.sound in any Scene. It is a single shared instance across the entire game. Key responsibilities: Adding, playing, and removing sound instances Global volume, mute, rate, and detune Automatic pause/resume when the browser tab loses/gains focus ( pauseOnBlur , default true ) Audio unlock handling for mobile browsers Spatial audio listener position (WebAudio only) Sound Instances Created via this.sound.add(key, config) . Each instance has its own playback state, volume, rate, detune, loop, pan, and seek properties. A sound must exist in the audio cache (loaded via the Loader) before it can be added. State flags: isPlaying (boolean), isPaused (boolean). const sfx = this . sound . add ( 'explosion' , { volume : 0.8 }); sfx. play (); // returns boolean sfx. pause (); // only works if isPlaying sfx. resume (); // only works if isPaused sfx. stop (); // resets to stopped state sfx. destroy (); // marks for removal from manager Common Patterns Playing Sounds Fire-and-forget -- this.sound.play(key, config?) adds, plays, and auto-destroys the sound on completion: this . sound . play ( 'explosion' ); this . sound . play ( 'powerup' , { volume : 0.5 , rate : 1.2 }); Retained reference -- this.sound.add(key, config?) then call play() on the instance: const laser = this . sound . add ( 'laser' ); laser. play (); // Later: laser.stop(), laser.volume = 0.3, etc. Volume, Rate, and Detune Each property can be set per-sound or globally on the manager. Global and per-sound values combine (for rate/detune, they multiply via calculateRate() ). // Per-sound sound. volume = 0.5 ; // 0 to 1 sound. setVolume ( 0.5 ); // chainable alternative sound. rate = 1.5 ; // 0.5 = half speed, 2.0 = double speed sound. setRate ( 1.5 ); sound. detune = 200 ; // cents, -1200 to 1200 sound. setDetune ( 200 ); // Global (affects all sounds) this . sound . volume = 0.8 ; this . sound . setVolume ( 0.8 ); this . sound . rate = 1.0 ; this . sound . setRate ( 1.0 ); this . sound . detune = 0 ; this . sound . setDetune ( 0 ); The effective playback rate is: sound.rate * manager.rate * detuneRate where detuneRate = Math.pow(1.0005777895065548, sound.detune + manager.detune) . Looping // Via config at creation const bgm = this . sound . add ( 'music' , { loop : true }); bgm. play (); // Toggle during playback bgm. loop = false ; bgm. setLoop ( false ); // chainable The LOOPED event fires each time the sound loops back to the start. The LOOP event fires when the loop property changes. Seeking sound. seek = 5.0 ; // jump to 5 seconds in sound. setSeek ( 5.0 ); // chainable console . log (sound. seek ); // current playback position in seconds Setting seek on a stopped sound has no effect. Stereo Panning sound. pan = - 1 ; // full left sound. pan = 0 ; // center sound. pan = 1 ; // full right sound. setPan ( 0.5 ); // chainable Uses StereoPannerNode , if it exists, on WebAudio. On HTML5 Audio, the pan property fires events but has no audible effect. Audio Sprites and Markers Audio sprites combine multiple sounds into a single audio file with a JSON config (generated by the audiosprite tool). The JSON must be loaded separately. // In preload this . load . audioSprite ( 'sfx' , 'assets/sfx.json' , [ 'assets/sfx.ogg' , 'assets/sfx.mp3' ]); // In create this . sound . playAudioSprite ( 'sfx' , 'explosion' ); this . sound . playAudioSprite ( 'sfx' , 'coin' , { volume : 0.5 }); // Or add for retained control const sprite = this . sound . addAudioSprite ( 'sfx' ); sprite. play ( 'explosion' ); The JSON spritemap entries are automatically converted to markers with name , start , duration , and optional loop . Manual markers -- you can also add markers to any sound: const sound = this . sound . add ( 'longtrack' ); sound. addMarker ({ name : 'intro' , start : 0 , duration : 5 }); sound. addMarker ({ name : 'loop' , start : 5 , duration : 20 , config : { loop : true } }); sound. addMarker ({ name : 'outro' , start : 25 , duration : 3 }); sound. play ( 'intro' ); // Later sound. play ( 'loop' ); Marker API on BaseSound: addMarker(marker) , updateMarker(marker) , removeMarker(markerName) . Background Music Pattern this . bgm = this . sound . add ( 'theme' , { loop : true , volume : 0.4 }); this . bgm . play (); // Stop on scene shutdown: this.bgm.stop(); The manager's pauseOnBlur (default true ) automatically pauses all sounds when the tab loses focus. Spatial Audio (WebAudio Only) Spatial audio uses the Web Audio PannerNode to position sounds in 2D/3D space relative to a listener. // Set the listener position (typically your camera or player) this . sound . setListenerPosition ( 400 , 300 ); // Or update directly: this.sound.listenerPosition.set(x, y); // Create a spatialized sound with a source config const enemy = this . sound . add ( 'roar' , { source : { x : 800 , y : 300 , refDistance : 50 , maxDistance : 2000 , rolloffFactor : 1 , distanceModel : 'inverse' , panningModel : 'equalpower' , follow : enemySprite // auto-track a Game Object's x/y } }); enemy. play (); You can set sound.x and sound.y directly on a WebAudioSound to reposition it at any time. If follow is set to an object with x / y properties, the spatial position updates automatically each frame. setListenerPosition() defaults to the center of the game canvas if called with no arguments. Muting // Per-sound sound. mute = true ; sound. setMute ( true ); // Global this . sound . mute = true ; this . sound . setMute ( true ); Querying Sounds this . sound . get ( 'coin' ); // first sound with key, or null this . sound . getAll ( 'coin' ); // all sounds with key this . sound . getAll (); // every sound in the manager this . sound . getAllPlaying (); // all currently playing sounds this . sound . isPlaying ( 'coin' ); // true if any 'coin' sound is playing this . sound . isPlaying (); // true if any sound is playing Removing and Stopping this . sound . stopAll (); // stop all sounds, fires STOP_ALL this . sound . stopByKey ( 'coin' ); // stop all sounds with key, returns count this . sound . pauseAll (); // pause all, fires PAUSE_ALL this . sound . resumeAll (); // resume all, fires RESUME_ALL this . sound . remove (soundInstance); // destroy + remove specific sound this . sound . removeByKey ( 'coin' ); // destroy + remove all with key, returns count this . sound . removeAll (); // destroy + remove everything Decoding Audio at Runtime (WebAudio Only) this . sound . decodeAudio ( 'key' , base64StringOrArrayBuffer); // Or batch: this.sound.decodeAudio([{ key: 'sfx1', data: buf1 }, { key: 'sfx2', data: buf2 }]); this . sound . on ( 'decoded' , ( key ) => { /* one done */ }); this . sound . on ( 'decodedall' , () => { /* all done */ }); Configuration Reference SoundConfig Property Type Default Description mute boolean false Whether the sound is muted volume number 1 Volume, 0 (silence) to 1 (full) rate number 1 Playback speed (0.5 = half, 2.0 = double) detune number 0 Detuning in cents (-1200 to 1200) seek number 0 Start playback position in seconds loop boolean false Whether the sound should loop delay number 0 Delay before playback starts, in seconds pan number 0 Stereo pan, -1 (left) to 1 (right) source SpatialSoundConfig null Spatial audio configuration (WebAudio only) SpatialSoundConfig Position: x (0), y (0), z (0) -- source position in world space.
