NPCA110M Audio Enhancing Engine and CODEC
Product Brief
November 2011
Revision 1.0
General Description
The Nuvoton NPCA110M device is a member of Nuvoton’s
Sound Enhancing family optimized for mobile applications
such as tablets, mobile phones and netbooks.
It provides CODEC functionality to support stereo
microphone inputs and either dual-stereo DACs or digital
outputs, for built-in speakers or a headphone jack.
The NPCA110M 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 Maxx family of devices includes:
■ High-performance, 24-bit audio enhancing device pre-
programmed with Waves MaxxAudio 3 algorithms
■ Optional Audio ADC with stereo microphone support
■ Optional Audio DAC
■ Digital I/O and other features for high-performance
