Answer 1

I followed Abdusha's approach but my output file had no audio plus the size was very small as compared to the input. After looking into it, a fix I made was in "pullGenericOutput" function. After AudioUnitRender call:

AudioUnitRender(genericOutputUnit,
                                   &flags,
                                   &inTimeStamp,
                                   busNumber,
                                   numberFrames,
                                       bufferList);

inTimeStamp.mSampleTime++; //Updated

increment the timeStamp by 1. After doing this, the output file was perfect with effects working. Thanks. Your answer helped a lot.
