WebAudio Reliability Fixer

Ensure stable audio playback across all browsers and devices.

Workflow

1. Check Autoplay Policy

   • Rule: AudioContext must start in suspended state.
   • Resume: Must call Tone.start() or context.resume() inside a click or keydown event.
   • Diag: Check Tone.context.state on load.

2. Inspect Scheduling

   • Lookahead: Is Tone.context.lookAhead sufficient? (Default 0.1s).
   • Latency: Is the main thread blocked? Audio runs on a separate thread, but scheduling happens on main.

3. Verify Cleanup

   • Oscillators: Must call stop() and dispose().
   • Effects: Connect/Disconnect properly to avoid graph leaks.

4. Buffer Management

   • Are buffers loaded before playback starts?
   • Check Tone.loaded() promise.

Example

Input: "Audio crackles during the game."

Action:

1. Check src/utils/audio/audioEngine.ts.
2. See extensive object creation in the render loop.
3. Fix: Reuse synth instances. Pre-calculate notes.
4. Increase Tone.context.lookAhead if CPU usage is high.

Output: "Optimized synth pooling in src/utils/audio/audioEngine.ts to reduce garbage collection pauses. Increased lookahead to 0.2s."

Skill sync: compatible with React 19.2.6 / Vite 8.0.10 / Tailwind 4.2.4 baseline as of 2026-05-20.
