The ADAU144x SigmaDSP audio processor family from Analog Devices handles multiple input signals to ease design constraints and increase processing speed in multifunction automotive audio designs. With an audio instruction set, the ADAU1442, ADAU1445, and ADAU1446 SigmaDSP audio processors incorporate a flexible audio routing matrix (FARM) that allows automotive audio subsystem engineers to increase the processing speed and reduce the complexity of audio signal routing and clocking issues associated with CD changers, MP3 and DVD players, satellite radios, GPS navigation systems, and other asynchronous audio sources. Using the FARM solution, system designers can compensate for the real-world limitations of speakers, amplifiers, and listening environments, resulting in audio quality improvement through speaker equalization, multiband compression, limiting, and third-party-branded algorithms.
