New Function : Audio Description
Audio description [From Wikipedia, the free encyclopedia]
Audio description refers to an additional narration track for blind and
visually impaired consumers of visual media, including television and movies,
dance, opera, and visual art.
For simplicity, this article focuses on the most common venues for
description: TV and film.
The description narrator talks through the presentation, describing what is
happening on the screen during the natural pauses in the audio (and
sometimes during dialogue if deemed necessary).
The sound is monaural, by its nature not the best quality audio.
The visual interfaces used to turn on SAP are a problem for blind people.
New Function : Audio Description
New Function : Dolby Digital Plus
Audio encoding/compression
Dolby Digital (also known as AC-3): is a lossy audio compression format.
It supports channel configurations from mono up to six discrete channels
(referred to as "5.1"). This format first allowed and popularized surround
sound. It was first developed for movie theater sound and spread to
Laserdisc and DVD. It has been adopted in many broadcast formats including
all North American digital television (ATSC), DVB-T, direct broadcast satellite,
cable television, DTMB, IPTV, and surround sound radio services. It is also
part of both the Blu-ray and the now defunct HD DVD standards. Dolby
Digital is used to enable surround sound output by most video game
consoles. Several personal computers support converting all audio to Dolby
Digital for output.
Dolby Digital Plus: audio codec based on Dolby Digital that is backward
compatible, but more advanced. The DVD Forum has selected Dolby Digital
Plus as a standard audio format for HD DVD video. It supports data rates up
to 6 Mbyte/s, an increase from Dolby Digital's 640 kbit/s maximum. Dolby
Digital Plus is also optimized for limited data rate environments such as
Digital broadcasting.
New Function : SRS TruSurround HD
Dialog Clarity. Audio creators today have more sound tools than ever to
work with, and more channels to put sound in. So naturally, they create rich,
dense audio for any purpose--movies, TV, music and games. Problem is,
with such heavily layered audio tracks, sometimes the vocals and dialog get
lost in the shuffle ... or buried under sound effects. Dialog Clarity boosts the
frequency range of the human voice in a way that makes the human voice
rise above the audio effects, so you can hear clearly every word you're
supposed to hear.
Immersive Surround Sound. This is the core technology of all the
TruSurround suites, and it processes any multichannel input, sending it to
two or three TV speakers after some very sophisticated processing. This
allows the listener to perceive enveloping surround sound from just the TV
speakers or external speaker bar. Rear and surround channels are processed
separately from front channels, and through our study of psychoacoustics
and knowing the difference between how sound is perceived front to back,
we process and adjust the surround channels' waveforms so they are
perceived as coming from behind the listener.
, and the restoration really is magic.
New Function : SRS TruSurround HD
Improved Bass. We know small speakers cannot reproduce deep bass. It's
physically impossible. But bass sounds are always accompanied by overtones,
and if your ears are given all the overtones, your perception will fill in the
`missing fundamental.' SRS patented bass technology was developed based
on an amazing combination of psychoacoustic understanding and technical
know-how, managing to restore the sensation of deep bass. It identifies the
signals that cannot be reproduced, and restores and boosts the overtones.
It's all in your head, courtesy of some nifty audio wave processing, and the
restoration really is magic.
High Frequency Clarity. Techniques used in digital compression or
broadcast transmission can reduce the clarity of audio content, leaving you
with a rather lackluster audio experience. SRS' premium high definition
technology restores clarity by enhancing the high frequency content,
bringing into focus the rain falling or wind howling in a movie scene or the
cymbals and acoustic guitar strumming in your favorite song.

Description
The NTP-3200 is a single chip full digital audio amplifier including power
stage for stereo amplifier system. NTP-3200 is integrated with versatile
digital audio signal processing functions, high-performance, high-fidelity
fully digital PWM modulator and two high-power full bridge MOSFET
power stages.
The NTP-3200 receives digital serial audio data with sampling frequency
from 8KHz to 192KHz. It delivers 2 x 20 watt in stereo mode without heat
sink. The NTP-3200 has mixer and Bi-Quad filters which can be used to
implement the essential audio signal processing functions like loudness
control, loud speaker response compensation and parametric equalizers.
All the functions of the NTP-3200 can be controlled by internal register
values via I2C host interface bus.
