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 WavesMaxxAudio 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, MaxxBassuses 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.
