1     Functions

Audio Object Identification (CAE-AOI):

Receives Audio Scene Geometry The spatial arrangements of the Audio Objects.
Audio Objects The individual input Audio Objects
Identifies The Audio Objects.
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

Note that the Audio Object Identification AIM should be able to parse either an Audio-Visual Scene Geometry or its Audio Scene Geometry subset.

3    Input/Output Data

Table 1 specifies the Input and Output Data of the Audio Object Identification AIM.

Table 1 – I/O Data of the Audio Object Identification AIM

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.

8     Conformance Testing

Table 2 provides the Conformance Testing Method for the CAE-AOI AIM. Conformance Testing of the individual AIMs of the CAE-AOI AIM are given by the individual AIM Specification.

If a schema contains references to other schemas, conformance of data for the primary schema implies that any data referencing a secondary schema shall also validate against the relevant schema, if present and conform with the Qualifier, if present.

Table 2 – Conformance Testing Method for CAE-AOI AIM

Receives Audio Scene Geometry Shall validate against Audio Basic Scene Geometry schema.
Audio Objects Shall validate against Audio Object schema.
Audio Data shall conform with Audio Qualifier.
Produces The Audio Instance IDs Shall validate against Instance ID schema.
