Creates a positional audio entity.
This uses the
Web Audio API.
TIP
You need to have an <AudioListener> component in your scene in order to use <Audio>and <PositionalAudio>components.

<PerspectiveCamera position={{ x: 3, y: 3, z: 3 }} lookAt={{ x: 0, y: 0, z: 0 }}>
<AudioListener />
</PerspectiveCamera>
<Car>
<PositionalAudio autostart loop refDistance={10} volume={0.2} source={'/audio/car-noise.mp3'} />
</Car>
