<p>This class is both a source and a sink and just let the audio pass through. It can be used standalone but maybe is of more use when inheriting from it. For example if you want to snoop in on an audio streem without affecting it, just reimplement the writeSamples method and you have access to the samples. Just remember to call the sinkWriteSamples method to forward the samples. </p>
