Abstract

Technical Specification: Context-based Audio Enhancement (MPAI-CAE) V2.1 specifies technologies that improve the user experience for audio-related applications including entertainment, communication, teleconferencing, gaming, post-production, restoration etc. in a variety of contexts such as in the home, in the car, on-the-go, in the studio etc. using context information to act on the input audio content, and potentially deliver the processed output via an appropriate protocol. MPAI-CAE specifies four Use Cases and one Composite AIM. The Use Cases are: Emotion Enhanced Speech (EES), Audio Recording Preservation (ARP), Speech Restoration System (SSR), and Enhanced Audioconference Experience (EAE); the Composite AIM is Audio Scene Description (ASD).  Each Use Case normatively defines:  1. The Functions of the AIW and of the AIMs.  2. The Connections between and among the AIMs.  3. The Semantics and the Formats of the input and output data of the AIW and the AIMs.  The word normatively implies that an Implementation claiming Conformance to:  1. An AIW, shall:  a. Have the AIW Function specified in the appropriate Section of Chapter 4.2.  b. Have all its AIMs and their Connections conforming with the AIW Reference Model specified in the appropriate Section of Chapter 4.2.  c. The AIW and AIM input and output data should have the Formats specified in the appropriate Subsection of Section 6.  2. An AIM, shall:  a. Have the AIM Function specified by the appropriate Section of Chapter 4.2.  b. Have input and output data Formats conforming with the appropriate Subsection of Section 6.  c. Receive as input and produce as output data having the Format specified in Section 6.  3. A data Format, the data shall have the Format specified in Section 6.  Users of this Technical Specification should note that:  1. This Technical Specification defines Interoperability Levels but does not mandate any.  2. Implementers are free to decide the Interoperability Level their Implementation should satisfy.  3. Implementers can use the Reference Software specification to develop their Implementations.  4. The Conformance Testing specification can be used to test the conformity of an Implementation to this Standard.  5. Performance Assessors can assess the level of Performance of an Implementation based on the Performance Assessment specification of this Standard.  6. Implementers and Users should consider the notices and disclaimers of Annex 2.  MPAI-CAE V2.1 includes:  1. The Scope (This Chapter)  2. Terms and Definitions  3. Normative and Informative References  4. Use Cases  5. Audio Scene Description Composite AIM 6. Data Types  7. Annexes (general concerns, some informative) This version of the MPAI-CAE Technical Specification has been developed by the CAE-DC Development Committee. Future Versions may revise and/or extend the Scope of the Standard.
