[protected]

Reads the audio data from the source buffer, converts the number of channels and the sample rate and copies the result to the destination buffer

const TDesC8 & aSrcBuffer	The source buffer containing the audio data to convert.
TDes8 & aDstBuffer	The destination buffer - assumed big enough

			TInt	aFromChannels,
			TInt	aToRate,
			TInt	aToChannels
