GENERAL DESCRIPTION

The ADAU1701 is a complete audio system-on-a-chip including a 28/56-bit audio DSP, ADCs and DACs, and microcontroller-like control interfaces. Signal processing includes equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, speaker

compensation, and stereo image widening. These algorithms can be used to compensate for the real-world limitations of speakers, amplifiers, and listening environments, resulting in a dramatic improvement of perceived audio quality.
