NPCA110B Audio Enhancing Engine and CODEC

Product Brief

November 2011

Revision 1.0

General Description

The Nuvoton NPCA110B device is a member of Nuvoton’s

Sound Enhancing family optimized for low cost TV, portable

devices such as docking stations for MP3-players and mobile

phones, Multi-Media speakers, PC monitor speakers and

Boom boxes.

The NPCA110B integrates Waves MaxxAudio-3 Lite

sound enhancement algorithms. These are proprietary,

patented, psychoacoustic algorithms that compensate for

the acoustic limitations of small CE devices.

MaxxAudio-3 Lite 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 distortion.

The MaxxAudio-3 Lite software suite provides an additional

algorithm to design a resonance-free audio system: Maxx-

EQ provides a flexible equalizer with 10 bands.

The NPCA110B enables digital control over the volume and

bass, replacing traditional analog potentiometers.

The Maxx family of devices includes:

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

programmed with Waves MaxxAudio-3 Lite 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.
