Note that, for stereo, each sample is double the size of an audio sample. Therefore, 1024 bytes of mono PCM is 512 samples, but 1024 bytes of stereo PCM is 256 samples.  Therefore, you should set
	fDurationInMicroseconds = 512*1000000/<sampling-frequency>
for mono, and
	fDurationInMicroseconds = 256*1000000/<sampling-frequency>
for stereo.
