NPCA110M

  NPCA110M Audio Enhancing Engine and CODEC Product Brief November 2011 Revision 1.0 NPCA110M Audio Enhancing Engine and CODEC 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 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. ...
