4.3.Init

This function initializes all internal variables and parameters. It is called by the framework (CAudioProcessing class). In this method, the object should initialize all its memory to appropriate values that match the device description specified in the toolbox methods (getXmlFileInfo, etc)

void CAudioObject::init()
{
}

If the audio object requires additional configuration variables, then the user must also implement the method to initialize that data via assignAdditionaConfig(). For more details, refer Audio Object Additional Configuration.
If this method is not overwritten, it is an empty method that will not do anything.
