NPCA110P Audio Enhancing Engine and CODEC

Product Brief

November 2011

Revision 1.0

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.

The Maxx family of devices includes:

■ High-performance, 24-bit audio enhancing engine pre-

programmed with Waves MaxxAudio 3 algorithms

■ Optional Audio ADC

■ Optional Audio DAC

■ Digital I/O and other features for high-performance

audio systems

The MaxxAudio Graphical User Interface (GUI) enables

sound engineers to easily tune the device and customize

presettings for different audio products.
