This function is called every time an audio interrupt is received and when the audio object is in the transition state of switching from “NORMAL / STOP” to “MUTE” processing state. The calc() function is called from here with NORMAL / STOP as the active state and the output is ramped down linearly. The ramp-down time is fixed as 50 ms. The ramp step and number of times this function need to be called is computed during the start of the ramp period.
This function takes pointers to input and output audio streams and is called by the CAudioProcessing class when an audio interrupt is received.
void CAudioObject::rampDown(xAFAudio** inputs, xAFAudio** outputs);
