<div class="textblock"><p>A base class for audio audioringbuffer implementations. </p>
<p>This object is the base class for audio ringbuffers used by the base audio source and sink classes.</p>
<p>The audioringbuffer abstracts a circular buffer of data. One reader and one writer can operate on the data from different threads in a lockfree manner. The base class is sufficiently flexible to be used as an abstraction for DMA based audioringbuffer as well as a pure software implementations.</p>
