3    I/O Data

Table 1 specifies the Input and Output Data of the Audio Object Acquisition (CAE-AOA) AIM.

Table 1 – I/O Data of the Audio Scene Management (CAE-ASM) AIM

Input Description
User Command Instruction directing the operation of the CAE-AOA AIM.
Listener Point Of View Position and Orientation of the Listener.
Sensor Output May be an Audio Object or Audio Data without Qualifier.
Audio Object An Audio Object from a Storage Device, e.g., the Repository.
Audio Scene Descriptors
Output Description
Audio Object The acquired Audio Object. If the sensor only provided Audio data, Qualifier information is provided in User Command.

8    Conformance Testing

Table 2 provides the Conformance Testing Method for the Audio Scene Management (CAE-ASM) AIM.

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 the Audio Scene Management (CAE-ASM) AIM

Receives User Command Shall validate against User Command schema.
Sensor Output Shall validate against Audio Object schema.
Audio Object Shall validate against Audio Object schema.
Produces Audio Object Shall validate against Audio Object schema.
