November 2011 Revision 1.0 NPCA110P Audio Enhancing Engine and CODEC General Description Outstanding Features The Nuvoton NPCA110P device is a member of Nuvoton’s Sound Enhancing family optimized for portable devices such as docking stations for MP3-players and mobile phones, MultiMedia speakers, PC monitor speakers and Boom boxes. ■ The NPCA110P integrates Waves MaxxAudio 3 sound enhancement algorithms. These are proprietary, patented, psychoacoustic algorithms that compensate for the acoustic limitations of small CE devices. ■ ■ ■ ■ ■ — The MaxxAudio 3 algorithms enable reproduction of rich content, with a wide dynamic range and a full frequency range, on a limited audio system. For low-frequency reproduction, MaxxBass uses a patented psychoacoustic technique to create a perceived low bass, which can be extended up to 1.5 octaves lower than the original. This technique reproduces full and rich sounding bass tones. Power handling is done by MaxxVolume, which utilizes the power amplifiers and speakers to their full extent yet avoids clipping and distortions. The MaxxAudio 3 software suite provides additional algorithms that enhance the overall sound quality, such as Maxx3D, which widens the stereo image, and MaxxTreble, for reproducing crystal clear high frequencies. To design a resonance-free audio system, MaxxEQ provides a flexible equalizer with 10 bands. The NPCA110P enables digital control over the Volume and Bass, replacing traditional analog potentiometers. Additional digital controls for selecting a specific music style (Jazz, Vocal, Rap, Classical, etc.) can also be added.
