NPCA110P Audio Enhancing Engine and CODEC
General Description
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, Multi-
Media 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 algo-
rithms 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. Addition-
al digital controls for selecting a specific music style (Jazz,
Vocal, Rap, Classical, etc.) can also be added.
