Provision of immersive audio capture normative example solutions to speed up deployment of a fully end-to-end IVAS ecosystem.
Target Device Specifications:
- Definition of a set of target devices or target device types
- Definition of minimum performance requirement/objective criteria for raw microphone signal performance and characteristics
- Definition of requirements for signals based on target devices or target device types
- Collection of a set of target devices or target device types
- Collection of common database for target devices
Solution Development and Evaluation:
- Development of immersive audio capture example solutions for target devices
- Evaluation of available immersive audio capture example solutions based on relevant sending side terminal audio quality test methods defined in TS 26.260
- Verification and potential revision of minimum performance requirements based on example solution performance under TS 26.260 test methods
- Specification of suitable example solutions
- Potential alignment with TS 26.260 and 26.261
Minimum Input Requirements:
- Raw/compensated microphone signals
