#Spatial audio PRO

Connect individual mono sources to an AVAudioEnvironmentNode, then connect the environment to the main mixer. Each source uses an available input bus. Set source position and rendering algorithm through setMixing(). Read getMixing().supported and the environment's applicableRenderingAlgorithms; available algorithms depend on output format and device route.

configure() controls listener position/orientation, distance attenuation, reverb, output type and output volume. Use either vector orientation or angular orientation in one update. Positions use meters. Distance and algorithm determine the spatial effect; headphones and speakers can sound different. The API does not enable head tracking by itself.

Source mixing also exposes supported obstruction, occlusion, reverb blend and source/head modes. The returned supported list describes which controls apply to the node. Do not assume every ordinary node supports every 3D mixing control.

#Runnable index.tsx

The example generates two quiet mono tones locally and places them to the listener's left/right. Buttons move the listener; position and source frequencies are displayed as text, so the controls can also be understood without hearing the scene. Stop/Close release the graph and buffers. Run without another script using the shared device-audio session.
