Remarks

This structure contains the context for the SRC block. The SRC performs sample rate conversion and pitch shifting. Members that are marked as Read are written by the Audio Control Processor (ACP) library and should only be read by your application. Members that are marked as Write are set by your application and are not changed by the ACP library. Members that are marked as Read/Write are set by your application but can be changed by the ACP library. For more information about the SRC, see Sample Rate Convertor (SRC) block in Overview of SHAPE.
