ABSTRACT:
A codec in a processor-based system handles at least two separate audio programs at the same time. This may be useful, for example, for simultaneously playing one audio program while recording another audio program. A first digital to analog converter pair may be coupled to a first mixer and a second digital to analog converter pair may include a second mixer. Thus, two separate audio programs may be handled at the same time, each by a separate digital to analog converter and mixer.
