Suitable for controlled immersive-audio pilots, conditional on testing the intended implementation and devices.

Why: Independent listening tests support useful audio-quality performance, and laboratory interoperability has progressed. Broad commercial reliability remains unestablished, while reverberant scenes can reduce quality at low bitrates.
Next: Validate the chosen codec revision, capture and rendering chain, bitrate, packet-loss behavior and interoperability before expanding deployment.

Constraints

End-to-end interoperability across the intended clients, devices and network requires validation.
Low-bitrate reverberant and diffuse scenes can lose perceptual quality.
Capture processing, format conversion and rendering can degrade spatial accuracy.
Older candidate listening tests do not establish correctness of every current implementation.
Broad independent commercial field evidence remains limited.
