NPCA110T Audio Enhancing Engine and DAC
Product Brief
November 2011
Revision 1.0
General Description
The Nuvoton NPCA110T device is a member of Nuvoton’s
Sound Enhancing family optimized for TV applications.
The NPCA110T 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.
Specifically designed for devices such as TV, MaxxLeveler
maintains a constant level of output for any given content.
This feature is useful for maintaining the same volume dur-
ing commercials or when switching TV channels.
The Maxx family of devices includes:
■ High-performance, 24-bit audio enhancing engine pre-
programmed with Waves MaxxAudio 3 algorithms
■ Optional Audio DAC
■ Optional Audio ADC
■ 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.

Features
Bus Interfaces
■ Synchronous Serial Interface (SSI)
— Compatible with I2S
— Master and slave timing support
■ I2C Interface
— Compliant with I2C-BUS Specification Revision 1.0,
1992
— Master or slave interface
— Supports 7-bit address mode
Audio Enhancing Engine
■ Processing Unit
— 24-bit accuracy
— 125 MIPs
Audio Algorithms
■ Sample frequency of 44.1 KHz or 48 KHz supported
■ MaxxBass
— Patented Waves MaxxBass psycho-acoustic bass
extension delivers a more natural sound than tradi-
tional bass boost technologies, which use EQ and
can overpower your system. MaxxBass analyzes
low frequencies to create harmonics that are per-
ceived as lower, deeper tones.
■ Maxx3D
— Maxx3D extends the span of stereo-side content
while maintaining the integrity of unprocessed cen-
ter content.
— Maxx3D for Speakers improves the stereo separa-
tion of speakers, widening the stereo field for optimal
imaging.
— Maxx3D for Headphones improves stereo percep-
tion, restoring the original listening balance to pro-
vide more natural sound.
■ MaxxTreble
— MaxxTreble delivers crystal clear high-frequency en-
hancement 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 In-
terface makes click-and-drag filter design fast and
easy.
■ 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 de-
livers clear, crisp dialog that does not disappear be-
hind loud music and effects.
■ Sub-Woofer
— Enables separating low-frequency content and di-
recting it into a third audio channel, for driving a sub-
woofer.
