* @class IOAudioStream
* @abstract This class wraps a single sample buffer in an audio driver.
* @discussion An IOAudioStream represents one hardware sample buffer as well as the direction
* of that buffer, the mix buffer that multiple clients mix into as well as a list of
* all of the formats to which this buffer can be set.
*
* When an IOAudioEngine is created during init time in the driver, an IOAudioStream must be
* created for each sample buffer in the device. Typically, the sample buffer will be interleaved
* (or single channel), as a non-interleaved buffer should be divided into multiple single-channel
* buffers (and multiple IOAudioStreams).
*
* Additionally, when an IOAudioStream is created it must have all of the possible formats (and
* allowed sample rates for each format) set and must have the currently set format specified
* (addAvailableFormat() and setFormat()).
