NUVOTON NPCA110P

 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.

Audio Enhancing Engine
■
■
MaxxVolume
— MaxxVolume is an all-in-one volume control, with
High-Level Compression to increase RMS levels,
Low-Level Compression to increase the clarity of
soft sounds, Noise Gating to eliminate signal and
system noise, and Leveling to smooth out volume
levels.
■
MaxxLeveler
— MaxxLeveler regulates the perceived volume of the
audio, keeping all audio content at the same level.
■
MaxxDialog
— MaxxDialog is a revolutionary new technology that
enables users to adjust center channel dialog levels
without affecting the rest of the audio mix. Based on
the Waves Center pro audio plug-in, MaxxDialog delivers clear, crisp dialog that does not disappear behind loud music and sound effects.
■
Sub-Woofer
— Enables separating low-frequency content and directing it into a third audio channel, for driving a subwoofer.
■
Filtering to eliminate noise induced by cellular phone
transmission
Processing Unit
— 24-bit
— 125 MIPs
Audio Algorithms
■
Sample frequency of 44.1 KHz or 48 KHz
■ MaxxBass
— Patented Waves MaxxBass psycho-acoustic bass
extension delivers a more natural sound than traditional bass boost technologies, which use EQ and
can overpower your system. MaxxBass analyzes
low frequencies to create harmonics that are perceived as lower, deeper tones.

Straps, Clocks, Supply and Package Information
■
Maxx3D
— Maxx3D extends the span of stereo-side content
while maintaining the integrity of unprocessed center content.
— Maxx3D for Speakers improves the stereo separation of speakers, widening the stereo field for optimal
imaging.
— Maxx3D for Headphones improves stereo perception, restoring the original listening balance to provide more natural sound.

❏
MaxxTreble
— MaxxTreble delivers crystal clear high-frequency enhancement for increased RMS without exceeding
the system ceiling. Its proprietary algorithm restores
luster to over-compressed formats to provide the
perfect listening experience.
MaxxEQ
— MaxxEQ provides the ability to design EQ curves
and shape sound with surgical precision, using up to
10 programmable filters with bell, shelf, low pass,
and high pass, plus adjustable frequency, gain, and
Q parameters. MaxxEQ’s intuitive Graphic User Interface makes click-and-drag filter design fast and
easy.
