+Babylon.js Audio Engine V2 - Comprehensive Guide
+
+Overview
+
+Babylon.js introduced AudioEngineV2 in version 8.0 as a modern, powerful replacement for the legacy audio engine. 
+It's based on the Web Audio API and is now fully decoupled from the graphics engine and scene, 
+making it more flexible and easier to use.
+
+Key Differences from V1
+
+Major Changes
+
+1. Decoupled Architecture: No longer tied to the graphics engine or scene
+2. Async Creation: All audio objects created with async functions instead of constructors
+3. Separate Sound Classes: StaticSound and StreamingSound are now distinct classes
+4. Audio Buses: Sound tracks renamed to "audio buses" with enhanced routing capabilities
+5. Modern JavaScript: Leverages latest WebAudio API features
+
+Migration Summary
+
+| Old (V1)                    | New (V2)                             |
+  |-----------------------------|--------------------------------------|
+| new Sound() constructor     | CreateSoundAsync() function          |
+| Sound with streaming option | Separate CreateStreamingSoundAsync() |
+| SoundTrack                  | AudioBus with chaining support       |
+| Coupled to Scene            | Independent audio engine             |
+
+Creating an Audio Engine
+
+// Create audio engine
+const audioEngine = await BABYLON.CreateAudioEngineAsync();
+
+// Create sounds (but don't play yet)
+const gunshot = await BABYLON.CreateSoundAsync("gunshot", "sounds/gunshot.wav");
+
+// Unlock audio engine (required for browser autoplay policies)
+await audioEngine.unlockAsync();
+
+// Now you can play sounds
+gunshot.play();
+
+Important: Browsers require user interaction before playing audio. Always call unlockAsync() after user interaction and before playing sounds.
+
+Sound Types
+
+Static Sounds (Buffered)
+
+Best for: Short sound effects, UI sounds, repeated playback
+
+const gunshot = await BABYLON.CreateSoundAsync("gunshot", "sounds/gunshot.wav");
+await audioEngine.unlockAsync();
+gunshot.play();
+
+Characteristics:
+- Entire sound loaded into memory
+- Low latency playback
+- Full playback control (looping, pitch, playback rate)
+- Can play multiple instances simultaneously
+
+Streaming Sounds
+
+Best for: Background music, long narrations, large audio files
+
+const music = await BABYLON.CreateStreamingSoundAsync(
+"music",
+"https://example.com/music.mp3"
+);
+await audioEngine.unlockAsync();
+music.play();
+
+Characteristics:
+- Only small chunks kept in memory
+- Memory efficient for long files
+- Limited playback options (no loopStart/loopEnd)
+- Potential initial buffering delay
+- Uses HTML5 <audio> element under the hood
+
+Sound Instances
+
+Each play() call creates a new instance, allowing overlapping playback:
+
+const sound = await BABYLON.CreateSoundAsync("alarm", "alarm.mp3", {
+maxInstances: 2  // Limit simultaneous playback
+});
+
+sound.play();  // Instance #1
+sound.play();  // Instance #2
+sound.play();  // Instance #3 - stops #1 automatically
+
+Key Points:
+- maxInstances controls simultaneous playback limit
+- Volume and stop() affect all instances
+- currentTime only affects newest instance
+- Property changes only affect new instances (not currently playing ones)
+
+Core Features
+
+Looping
+
+Three ways to loop sounds:
+
+// Option 1: During creation
+const sound = await BABYLON.CreateSoundAsync("bounce", "bounce.wav", {
+loop: true
+});
+
+// Option 2: Via property
+sound.loop = true;
+sound.play();
+
+// Option 3: Via play() options
+sound.play({ loop: true });
+
+Volume Control
+
+Volume ranges from 0 (silent) to 1 (100%), with values above 1 for boosting:
+
+// Engine-wide volume
+audioEngine.volume = 0.5;
+
+// Individual sound volume
+gunshot.volume = 0.75;
+
+// Fade in/out with duration and shape
+tone.setVolume(0, {
+duration: 3,
+shape: AudioParameterRampShape.Logarithmic
+});
+
+Available ramp shapes: Linear, Exponential, Logarithmic
+
+Stereo Panning
+
+Move sounds between left (-1) and right (+1) speakers:
+
+const sound = await BABYLON.CreateSoundAsync("gunshot", "gunshot.wav", {
+stereoEnabled: true  // Enable upfront to avoid delay
+});
+
+sound.stereo.pan = -1;  // Full left
+sound.stereo.pan = 1;   // Full right
+sound.play();
+
+Note: Set stereoEnabled: true during creation to avoid initialization delay
+
+Spatial Audio (3D Sound)
+
+Position sounds in 3D space with distance attenuation and directional audio:
+
+const bounce = await BABYLON.CreateSoundAsync("bounce", "bounce.wav", {
+spatialEnabled: true
+});
+
+// Attach to mesh for automatic position/rotation updates
+bounce.spatial.attach(mesh);
+
+await audioEngine.unlockAsync();
+bounce.play({ loop: true });
+
+// Or manually control position
+bounce.spatial.position.set(10, 0, 5);
+
+Spatial Features:
+- Distance-based attenuation
+- Directional audio (cone-based)
+- Doppler effect
+- One listener per audio engine
+- Attach to meshes for automatic positioning
+
+Audio Buses
+
+Buses group multiple audio sources for collective control and routing:
+
+Main Audio Bus
+
+The final destination before speakers (created automatically):
+
+// Access default main bus
+const mainBus = audioEngine.mainBus;
+mainBus.volume = 0.8;
+
+Limitations: No stereo pan or spatial audio (final output only)
+
+Intermediate Audio Buses
+
+Route multiple sounds through buses with effects:
+
+const musicBus = await BABYLON.CreateAudioBusAsync("music", {
+spatialEnabled: true
+});
+
+musicBus.spatial.attach(speakerMesh);
+musicBus.volume = 0.6;
+
+const song1 = await BABYLON.CreateSoundAsync("song1", "song1.mp3");
+const song2 = await BABYLON.CreateSoundAsync("song2", "song2.mp3");
+
+// Route both songs through the music bus
+song1.outBus = musicBus;
+song2.outBus = musicBus;
+
+// musicBus automatically routes to mainBus
+
+Features:
+- Chain buses together (no circular routing)
+- Apply stereo and spatial effects to grouped sounds
+- Reduce CPU usage (one spatial calculation for multiple sounds)
+
+Audio Analyzer
+
+Real-time frequency analysis for visualizations:
+
+const sound = await BABYLON.CreateSoundAsync("music", "music.mp3", {
+analyzerEnabled: true
+});
+
+sound.play({ loop: true });
+
+// Get frequency data every frame
+scene.onBeforeRenderObservable.add(() => {
+const frequencies = sound.analyzer.getByteFrequencyData();
+// frequencies is an array of volume levels per frequency band
+// Values: 0-255 (byte) or -∞ to 0 dB (float)
+});
+
+Browser Autoplay Considerations
+
+Modern browsers block audio until user interaction:
+
+// Pattern 1: Unlock on button click
+button.addEventListener("click", async () => {
+await audioEngine.unlockAsync();
+sound.play();
+});
+
+// Pattern 2: Create unmute button
+const unmuteButton = await audioEngine.createUnmuteButtonAsync();
+document.body.appendChild(unmuteButton);
+// Button automatically removes itself when audio unlocks
+
+Advanced Features
+
+Sound Buffers (Shared Audio Data)
+
+Share audio buffer between multiple sounds to save memory:
+
+const buffer = await BABYLON.CreateSoundBufferAsync("explosion", "explosion.wav");
+
+const sound1 = await BABYLON.CreateSoundAsync("exp1", buffer);
+const sound2 = await BABYLON.CreateSoundAsync("exp2", buffer);
+// Both sounds share the same audio data in memory
+
+Multi-Format Support
+
+Browser compatibility for different audio codecs:
+
+const sound = await BABYLON.CreateSoundAsync("music", [
+"music.ogg",  // Firefox, Chrome
+"music.m4a",  // Safari
+"music.mp3"   // Fallback (all browsers)
+]);
+// First supported format is automatically selected
+
+Microphone Input
+
+Capture and process microphone audio:
+
+const micStream = await navigator.mediaDevices.getUserMedia({ audio: true });
+const micSound = await audioEngine.createMicrophoneSoundAsync(micStream);
+micSound.play();
+
+Performance Considerations
+
+1. Use streaming sounds for files > 1MB or > 30 seconds
+2. Enable options during creation (spatialEnabled, stereoEnabled, analyzerEnabled) to avoid runtime delays
+3. Limit sound instances with maxInstances option
+4. Use audio buses to group sounds for collective spatial processing
+5. Dispose sounds when no longer needed to free memory
+
+Legacy Engine
+
+The old AudioEngine (V1) is deprecated but still available:
+
+// Enable legacy engine
+const engine = new BABYLON.Engine(canvas, true, { audioEngine: true });
+
+Migration strongly recommended for better performance and features.

-Babylon.js AudioEngineV2 - Implementation Guide
+BabylonJS AudioEngineV2 - Comprehensive Guide
 
-Overview
+What's New in AudioEngineV2
 
-The new AudioEngineV2 is Babylon.js's modern spatial audio engine that provides improved performance, better 3D audio positioning, and a cleaner async/await-based API. This project uses it extensively for cockpit sounds, voice alerts, weapon fire, and explosion effects.
+AudioEngineV2 is the modern audio engine for BabylonJS that replaces the older Engine.audioEngine approach. 
+Key improvements include:
 
-  ---
-Key Initialization Pattern
+- Async/Promise-based API: All audio operations are now asynchronous, ensuring proper initialization and loading
+- Better Web Audio API integration: Direct access to Web Audio API features
+- Improved spatial audio: Better 3D positional audio with automatic listener management
+- Modern browser compatibility: Built for current Web Audio standards
 
-1. Engine Creation (main.ts:613-620)
+Key Features and Capabilities
 
-this._audioEngine = await CreateAudioEngineAsync({
+Initialization Options:
+CreateAudioEngineAsync({
+volume: 1.0,                    // Master volume (0.0 - 1.0)
+listenerAutoUpdate: true,       // Automatically update listener position
+listenerEnabled: true,          // Enable spatial audio listener
+resumeOnInteraction: true       // Auto-resume on user interaction
+})
+
+Core Capabilities:
+- Spatial Audio: Automatic 3D positional audio with listener attachment
+- Non-spatial Audio: Standard 2D audio for UI sounds, music, voice-overs
+- Sound Creation: Async loading with createSoundAsync()
+- Listener Management: Attach listener to cameras for spatial audio tracking
+- State Management: Access to sound states (Started, Starting, Stopped, etc.)
+- User Interaction Unlocking: Modern browsers require user interaction before audio playback
+
+How to Initialize and Use It
+
+Initialization
+
+import { AudioEngineV2, CreateAudioEngineAsync } from "@babylonjs/core";
+
+// Create the audio engine
+const audioEngine: AudioEngineV2 = await CreateAudioEngineAsync({
 volume: 1.0,
-listenerAutoUpdate: true,    // Auto-update listener position
-listenerEnabled: true,        // Enable spatial audio
-resumeOnInteraction: true     // Auto-resume if browser suspends
+listenerAutoUpdate: true,
+listenerEnabled: true,
+resumeOnInteraction: true
 });
 
-Critical Configuration:
-- listenerAutoUpdate: Automatically updates the audio listener position based on the attached camera
-- listenerEnabled: Enables 3D spatial audio calculations
-- resumeOnInteraction: Handles browser autoplay policies gracefully
+Unlocking Audio (Required Before Playback)
 
-  ---
-2. Audio Engine Unlock (main.ts:174-176)
+// Must be called after user interaction (button click, VR entry, etc.)
+await audioEngine.unlockAsync();
 
-// Unlock audio engine on user interaction
-if (this._audioEngine) {
-await this._audioEngine.unlockAsync();
-}
+Creating Sounds
 
-Why this matters:
-- Modern browsers require user interaction before playing audio (autoplay policy)
-- Must be called BEFORE loading audio assets
-- Must be called during a user gesture event (button click, VR trigger, etc.)
-
-  ---
-3. Listener Attachment (main.ts:183-189)
-
-const camera = DefaultScene.XR?.baseExperience?.camera || DefaultScene.MainScene.activeCamera;
-if (camera && this._audioEngine.listener) {
-this._audioEngine.listener.attach(camera);
-debugLog('Audio listener attached to camera for spatial audio');
-}
-
-Spatial Audio Setup:
-- Attaches the audio listener to the VR camera (or fallback to main camera)
-- With listenerAutoUpdate: true, the listener position updates every frame
-- Critical for accurate 3D audio positioning in VR
-
-  ---
-Sound Creation Patterns
-
-Pattern 1: Static Sounds (Non-Spatial)
-
-Used for cockpit UI sounds like voice alerts (voiceAudioSystem.ts:75-83):
-
-const sound = await audioEngine.createSoundAsync(
-`voice_${fileName}`,
-`/assets/themes/default/audio/voice/${fileName}.mp3`,
-{
-loop: false,
-volume: 0.8,
-// No spatial properties = plays from camera position
-}
-);
-
-When to use:
-- Cockpit computer announcements
-- UI feedback sounds
-- Music/ambient background
-
-  ---
-Pattern 2: Looping Sounds with Dynamic Volume
-
-Used for thrust sounds (shipAudio.ts:25-32):
-
-this._primaryThrustSound = await this._audioEngine.createSoundAsync(
-"thrust",
-"/thrust5.mp3",
+// Spatial sound (3D positioned)
+const spatialSound = await audioEngine.createSoundAsync(
+"soundName",
+"/path/to/audio.mp3",
 {
 loop: true,
-volume: 0.2,
+volume: 0.5,
+spatialSound: true,  // Enable 3D positioning
+maxDistance: 100     // Distance attenuation
 }
 );
 
-Dynamic Volume Control:
-public updateThrustAudio(linearMagnitude: number, angularMagnitude: number): void {
-if (linearMagnitude > 0) {
-if (!this._primaryThrustPlaying) {
-this._primaryThrustSound.play();
-this._primaryThrustPlaying = true;
-}
-// Dynamically adjust volume based on thrust magnitude
-this._primaryThrustSound.volume = linearMagnitude;
-} else {
-if (this._primaryThrustPlaying) {
-this._primaryThrustSound.stop();
-this._primaryThrustPlaying = false;
-}
-}
-}
-
-  ---
-Pattern 3: One-Shot Sounds
-
-Used for weapon fire (shipAudio.ts:43-50):
-
-this._weaponSound = await this._audioEngine.createSoundAsync(
-"shot",

-Benefits:
-- Load once, play many times
-- No need to track playing state for one-shot sounds
-- Automatic sound pooling/overlap handling

-1. Sequential Voice Playback System
+Checking Sound State
 
-The VoiceAudioSystem demonstrates advanced sequencing (voiceAudioSystem.ts):
+import { SoundState } from "@babylonjs/core";
 
-// Queue a sequence of voice clips
-public queueMessage(
-sounds: string[],              // e.g., ['warning', 'fuel', 'danger']
-priority: VoiceMessagePriority,
-interrupt: boolean,
-repeatInterval: number,
-stateKey?: string
-): void {
-const message: VoiceMessage = { sounds, priority, interrupt, repeatInterval, stateKey };
-
-      // Priority-based insertion
-      const insertIndex = this._queue.findIndex(m => m.priority > priority);
-      if (insertIndex === -1) {
-          this._queue.push(message);
-      } else {
-          this._queue.splice(insertIndex, 0, message);
-      }
+if (sound.state === SoundState.Started || sound.state === SoundState.Starting) {
+// Sound is currently playing
 }
 
-Features:
-- Priority-based queue (HIGH, NORMAL, LOW)
-- Sequential playback: "warning" → "fuel" → "danger"
-- Interrupt capability for critical alerts
-- Auto-repeat with configurable intervals
-- State tracking to prevent spam

-2. Sound State Monitoring
+Unlock Pattern
 
-public update(): void {
-if (this._isPlaying && this._currentMessage) {
-const currentSound = this._sounds.get(currentSoundName);
-const state = currentSound.state;
+// CRITICAL: Unlock audio BEFORE entering VR and loading sounds
+// Unlock must happen on user interaction (button click, VR entry trigger)
+await audioEngine.unlockAsync();
 
-          // Check if sound finished
-          if (state !== SoundState.Started && state !== SoundState.Starting) {
-              this._currentSoundIndex++;
+// THEN load audio assets
+await loadAudioAssets(audioEngine);
 
-              if (this._currentSoundIndex < this._currentMessage.sounds.length) {
-                  this.playCurrentSound(); // Next in sequence
-              } else {
-                  // Sequence complete - check for repeat
-                  if (this._currentMessage.repeatInterval > 0) {
-                      this._queue.push({ ...this._currentMessage });
+Listener Management
+
+// Attach listener to camera BEFORE entering VR
+// This ensures spatial audio follows the user's head position
+if (camera && audioEngine.listener) {
+audioEngine.listener.attach(camera);
+}
+
+Spatial vs Non-Spatial Audio
+
+Spatial Audio: Use for environmental sounds (explosions, thrust, collisions)
+- These sounds have 3D positioning and distance attenuation
+- Attach sound sources to mesh positions
+
+Non-Spatial Audio: Use for UI, music, cockpit computer voice
+- These sounds play at constant volume regardless of position
+- Perfect for HUD feedback and narration
+
+Performance Considerations
+
+// Reuse sound instances rather than creating new ones
+// Use sound pooling for frequently played sounds (explosions)
+// Dispose sounds when no longer needed
+sound.dispose();
+
+Migration from Legacy Audio
+
+Old Pattern
+
+const sound = new Sound("name", "url", scene, callback, { loop: true });
+
+New Pattern
+
+const sound = await audioEngine.createSoundAsync("name", "url", { loop: true });
+
+Key Differences
+
+1. Async/Await: All operations are promise-based
+2. No Scene Parameter: Sounds are managed by the audio engine, not the scene
+3. Explicit Unlocking: Must call unlockAsync() after user interaction
+4. Listener Management: Explicitly attach listener to camera for spatial audio
+5. State Checking: Use SoundState enum instead of callbacks
+
+Example Implementation Pattern
+
+class VoiceAudioSystem {
+private _audioEngine: AudioEngineV2 | null = null;
+private _sounds: Map<string, StaticSound> = new Map();
+
+      async initialize(audioEngine: AudioEngineV2): Promise<void> {
+          this._audioEngine = audioEngine;
+
+          // Load all voice clips
+          for (const fileName of this.VOICE_FILES) {
+              const sound = await audioEngine.createSoundAsync(
+                  `voice_${fileName}`,
+                  `/assets/themes/default/audio/voice/${fileName}.mp3`,
+                  {
+                      loop: false,
+                      volume: 0.8
+                      // Non-spatial for cockpit computer voice
                   }
-              }
+              );
+              this._sounds.set(fileName, sound);
           }
       }
 }
 
-Sound States:
-- SoundState.Starting - Sound is initializing
-- SoundState.Started - Sound is currently playing
-- SoundState.Stopped - Sound has stopped/finished

-Asset Loading Strategy
+Performance Metrics:
+- Tokens Consumed: 20,906 tokens
+- Time Taken: Approximately 15-20 seconds for research and response generation
 
-Two-Phase Loading
-
-Phase 1: Visual Assets (main.ts:147-149)
-ParticleHelper.BaseAssetsUrl = window.location.href;
-await RockFactory.init(); // Load meshes, particles (no audio)
-this._assetsLoaded = true;
-
-Phase 2: Audio Assets (main.ts:179-180)
-// AFTER audio engine unlock!
-await RockFactory.initAudio(this._audioEngine);
-
-Why separate phases?
-- Audio engine MUST be unlocked before loading sounds
-- Unlock requires user interaction
-- Splitting prevents blocking on audio during initial load
-
-  ---
-Best Practices
-
-✅ DO
-
-1. Create audio engine early, unlock on user interaction
-   // During app initialization
-   this._audioEngine = await CreateAudioEngineAsync({...});
-
-// During level selection button click
-await this._audioEngine.unlockAsync();
-2. Attach listener to camera for spatial audio
-   this._audioEngine.listener.attach(camera);
-3. Load sounds once, play many times
-   this._sound = await audioEngine.createSoundAsync(...);
-   // Later...
-   this._sound.play(); // Reuse
-   this._sound.play(); // Works multiple times
-4. Track playing state for looping sounds
-   private _thrustPlaying: boolean = false;
-
-if (!this._thrustPlaying) {
-this._thrustSound.play();
-this._thrustPlaying = true;
-}
-5. Dispose sounds when done
-   public dispose(): void {
-   this._primaryThrustSound?.dispose();
-   this._weaponSound?.dispose();
-   }
-
-❌ DON'T
-
-1. Don't load audio before unlock
-   // ❌ WRONG - will fail in most browsers
-   await this._audioEngine.createSoundAsync(...);
-   await this._audioEngine.unlockAsync(); // Too late!
-2. Don't create new sounds on every play
-   // ❌ WRONG - memory leak
-   public playShot() {
-   const sound = await audioEngine.createSoundAsync('shot', '/shot.mp3');
-   sound.play();
-   }
-3. Don't forget to stop looping sounds
-   // ❌ WRONG - sound keeps playing forever
-   this._thrustSound.play();
-   // ... later, no stop() called
-
-  ---
-Performance Metrics
-
-Based on this implementation:
-
-- Initial Load: ~30% faster by deferring audio until unlock
-- Asset Load: Visual assets load first (meshes, textures), audio loads on-demand
-- Memory: Sounds are loaded once and reused (no duplicate instances)
-- Latency: One-shot sounds have minimal playback latency (~5-10ms)
-- VR Performance: Spatial audio updates automatically with camera (no manual calculations)

-Common Issues & Solutions
-
-Issue 1: Audio Not Playing
-
-Symptom: Sounds don't play, no errors
-Solution: Ensure unlockAsync() called during user gesture
-
-Issue 2: Spatial Audio Not Working
-
-Symptom: All sounds seem to come from center
-Solution: Verify listener is attached to camera:
-this._audioEngine.listener.attach(camera);
-
-Issue 3: Sounds Cut Off
-
-Symptom: Multiple rapid plays cut each other off
-Solution: For one-shot sounds, AudioEngineV2 handles overlap automatically. For spatial sounds, consider using sound pooling.
-
-Issue 4: Memory Leaks
-
-Symptom: Memory usage grows over time
-Solution: Always call dispose() on sounds when done
