The Audio Sensors (CAV-AUS) AIM:

Receives Audio Field What the Audio sensors capture.
Produces Basic Audio Object To Basic Audio Scene Description.

The Audio Sensors AIM is the set of Audio sensors of the CAV. Each sensor is served by an instance of the Audio Object Acquisition AIM, which receives what the sensor captures of the Audio Field and provides it as a Basic Audio Object: time-stamped on the CAV’s time base, its Qualifier stating the sensor, its intrinsic calibration and its mounting pose on the CAV.

An Implementation instantiates the Acquisition AIM once per sensor; the Basic Audio Objects of all sensors leave on one Port, each identifying its sensor.

3 I/O Data

Table 1 specifies the Input and Output Data of the Audio Sensors (CAV-AUS) AIM.

Table 1 – I/O Data of the Audio Sensors (CAV-AUS) AIM

Input Data Type Description
Audio Field Basic Audio Object The Audio Field as each sensor captures it.
Output Data Type Description
Basic Audio Object Basic Audio Object One Basic Audio Object per capture, time-stamped on the CAV’s time base, its Qualifier stating the sensor, its intrinsic calibration and its mounting pose on the CAV.

4 SubAIMs

Not implemented in the reference software of Stage 1.

8 Conformance Testing

Table 2 provides the Conformance Testing Method for the Audio Sensors (CAV-AUS) AIM: the data it receives and produces. If a schema references other schemas, conformance of data for the primary schema implies that data referencing a secondary schema shall also validate against that schema, if present, and conform with the Qualifier, if present.

Table 2 – Conformance Testing Method for the Audio Sensors (CAV-AUS) AIM

Receives Basic Audio Object Shall validate against the Basic Audio Object schema.
Produces Basic Audio Object Shall validate against the Basic Audio Object schema.
