Audio Object Identification (CAE-AOI) receives Audio Objects and their Scene Geometry and produces the Identities of the Audio Objects:
| Receives | Audio Scene Geometry | The spatial arrangements of the Audio Objects. |
| Audio Objects | The individual input Audio Objects | |
| Identifies | The Audio Objects. | Provides Audio Object Identifiers |
| Produces | The Audio Instance IDs | The Instance Identifier of the Audio Objects. |
2 Reference Model
Figure 1 depicts the Reference Architecture of the Audio Object Identification AIM.
Figure 1 – Audio Object Identification AIM
The Audio Object Identification AIM shall be able to parse either an Audio-Visual Scene Geometry or its Audio Scene Geometry subset.
3 I/O Data
| Input | Description |
|---|---|
| Audio Scene Geometry | The digital representation of the spatial arrangement of the Visual Objects of the Scene. |
| Audio Objects | The Audio Objects in the Audio Scene Geometry with an identifiable source target of identification. |
| Output | Description |
| Audio Instance Identifier | The Instance Identifier of the specific Audio Object. |
