THREE.JS / WEBAUDIO / TIMING

Make timing audible.

The pinned timing example schedules a positional ping exactly when five spheres change direction at the floor. Start is user-gesture gated; this contract uses a deterministic local WAV buffer in place of the absent official MP3.

Start the audio context to unlock the Timer, AudioListener, and PositionalAudio field.

The local generated WAV preserves AudioLoader, AudioListener, five positional sources, user-gesture unlock, exact direction-change triggering, timer controls, sampling, and teardown. The official MP3, exact page/pixel presentation, audio-device matrix, and whole-example fidelity remain separate.
