General Description
The Nuvoton NPCA110D device is a member of Nuvoton’s Sound Enhancing family optimized for Audio applications that use a digital (I2S) interface.
The NPCA110D integrates Waves MaxxAudio 3 sound enhancement algorithms. These are proprietary, patented, psychoacoustic algorithms that compensate for the acoustic limitations of small CE devices.
