/*************************************************
*
* AudioFrame class
*
* The AudioFrame class holds up to 60 ms wideband
* audio. It allows for adding and subtracting frames
* while keeping track of the resulting states.
*
* Note
* - The +operator assume that you would never add
* exact opposite frames when deciding the resulting
* state. To do this use the -operator.
*
* - _audioChannel of 1 indicated mono, and 2
* indicates stereo.
*
* - _payloadDataLengthInSamples is the number of
* samples per channel. Therefore, the total
* number of samples in _payloadData is
* (_payloadDataLengthInSamples * _audioChannel).
*
* - Stereo data is stored in interleaved fashion
* starting with the left channel.
