void	setData (unsigned char *pData, int bitsPerSample, int sampleCount, int channels, int sampleRate)
	pData is a pointer to a buffer of raw data. bitsPerSample should be 8, 16, or 32. If it is 8, sample values are unsigned (0-255). If it is 16 or 32, sample values are signed. channels is typically 1 or 2, but it can be larger. sampleRate is typically one of 8000, 16000, 22050, 44100, 48000, or 96000, but other sample rates could be used as well.

pData is a pointer to a buffer of raw data. bitsPerSample should be 8, 16, or 32. If it is 8, sample values are unsigned (0-255). If it is 16 or 32, sample values are signed. channels is typically 1 or 2, but it can be larger. sampleRate is typically one of 8000, 16000, 22050, 44100, 48000, or 96000, but other sample rates could be used as well.
