This world exists to verify that audio playback works.

On load, the SineSpeaker entity (the cyan sphere) plays a looping 440 Hz sine wave (audio/sine.wav, an exact 2 s / 880-cycle loop so it repeats seamlessly) through the engine's Kira mixer on the music channel.

How to test

Open the world — the tone autoplays. Enter Play mode if your client gates audio to play mode.
You should hear a steady, clean 440 Hz tone with no clicks at the loop boundary.

How it's built

audio/sine.wav — generated 16-bit mono PCM sine, 44.1 kHz, 0.6 amplitude.
scenes/main.scene — the SineSpeaker entity carries a Model (sphere) plus an Audio component (url = audio/sine.wav, looping = true, autoplay = true, sourceType = Music).
