DNSe3.0 Overview 中英双语不完全版
翻译时遇到个比较难的选择，到底是忠于原文一字不差的翻，还是忽略部分艰深晦涩的意思，以看得懂为首要。。。。。。
思考再三后决定平衡一下，除非出现有碍理解的情况，否则一律保留愿文意思，读起来可能会有些拗口，但也顾不得那么多了
许多长句虽然已做断句，但依然不易一下子理解，还请麻烦多读几遍~
有一定英语基础的同志尽量直接看原文，理解原文比理解译文要轻松些。

DNSe 3.0 : Music That Comes Alive
Samsung Electronics Co., Ltd. is one of the fastest growing global brands, and a proven leader in semiconductor, telecommunication, digital media and digital convergence technologies. Over the years, Samsung has built and reaffirmed its reputation for improving customers’ lives with groundbreaking technological advancements.
After years of research on audio DSP and acoustics, Samsung launched its new sound enhancing technology, Digital Natural Sound engine (DNSe), in 2003. Since then, Samsung has continued to fine-tune this technology, investing in R&D on DNSe, to provide the ultimate in sound fidelity on Samsung products ranging from TVs, DVD players, stereo systems, and MP3 players.
In 2008, Samsung newly introduces DNSe 3.0 for MP3 players.
The aim of the DNSe 3.0 is also to restore the best sonic experience to the end user, which has always been their main goal.
For this, Samsung added several new features and did further refinement on existing functions.
The new sound engine yields higher quality sound with more natural effects than conventional methods by reproducing the “genuine” stereo sound intended by the music content creators. It achieves this by overcoming the limitations from earphones, less-than-ideal speakers and lossy-compressed audio files to offer realistic stereo, true to life treble and deep bass sounds.
In addition, Samsung has sculpted ideal listening experiences that further compensate for the native restrictions of portable music and multimedia players. Using embedded technologies that include 3D, Street Mode, Clarity, Audio Upscaler, Variable Speed Playback and Concert Hall, Samsung has tweaked these functions into user-centric presets, ranging from Rock to Classic, Vocal to Bass Boost, that further heighten the music experience.
With any DNSe-enabled device, you can go on an aural journey…from the Met where symphony orchestras come alive to the hottest underground club where bass-enhanced music gets you dancing. Whichever type of music you listen to, Samsung’s DNSe technology will ensure that it comes alive in your ears.
Samsung’s DNSe 3.0 technology will be found in the YP-Q1 MP3 player first, which will be on market in 2008.
DNSe 3.0, as well as future upgraded versions of the sound engine technology, will be incorporated in all of Samsung’s new MP3 players. More information on these devices will be available at a later date.

以上内容暂时不译，对三星有爱的可以粗略看下。
2.< Natural Stereo Sound > < 自然立体声音效 >
Stereo sound is important to music lovers because it translates what would otherwise be a flat and unnatural sound to music that sounds as if it is being played live in your ears. However, by nature of the physical limitations of earphones, it is generally difficult to achieve a satisfying stereo listening experience because of the unnatural channel separation to the left and right earbuds. Even stereo speakers on portable devices pose an acoustic dilemma because they are too close together to simulate an ideal stereo environment.
立体声对音乐爱好者而言是重要的，因为它能转换那些音乐中单调、不自然的声音，使它听上去像是在你耳朵里直接播放一样。然而，由于耳机物理上的先天限制，使要获得满意的立体声听觉体验变得普遍困难，因为左、右耳塞分声道时的不自然。甚至便携式装置上的立体声扬声器也产生声学上的困境，因为它们在一起太靠近以至于不能模拟出理想的立体声环境。
Achieving a genuine 3D stereo sound image requires the exact positioning of the left and right speakers as well as the listener in order to achieve the perfect balance of sound going to left and right. This means having some of the left channel being heard in the right ear, and a portion of the right channel being audible in the left ear.
要得到一种真正的3D立体声效果，除了需要听者精确的位置，同时也需要左、右扬声器精确的位置，为了实现声音在传到左、右耳时的完美平衡。这就是说，有一些左声道的声音会被右耳听到，而一部分右声道的声音会被左耳听到。
Samsung’s DNSe 3.0 successfully achieves this optimal balance through proper signal processing, enabling portable music devices with earphones or speakers to recreate the ideal stereo image intended by music creators. Audiophiles can now enjoy the same acoustic fidelity on the go that they would achieve with their engineered home stereo system.
三星的DNSe 3.0通过恰当的信号处理，成功地取得了这个最理想的平衡，让使用耳机或扬声器的便携式音乐设备能还原音乐家预期的理想的立体声效果。现在，高保真音响爱好者们能在路上享受他们在家庭影院中得到的相同声音保真度了。
3.< Deep Bass Resonance > < 重低音回响 >
The physical limitations of earphones or small speakers also limit the reproduction of a thick, full and meaty bass sound; often, only bass and upper bass registers are audible. Depending on the type of music you listen to and what the original intent of the music creators are, this could lead to a less-than-satisfying listening experience. For instance, the low bass sounds in hip hop or dance music provide the base for the music; the bass line is the groove of the song that people dance to. Without the deep bass sounds, the music would lose a dimension in its audible experience.
耳机或者小型扬声器的物理局限也限制了厚重、饱满、充实的低音的再现；通常只有普通低音和较高的低音音域能被听到。比较你听到的这种音乐和音乐家原来的预期效果，就可能导致不满意的听觉体验。举个例子，在嘻哈音乐和舞曲中，重低音提供了这种音乐的基础；这低音线是人们听歌跳舞的节奏。没有了重低音，这种音乐在听觉体验中会失去特点。
To correct these limitations, DNSe uses a psycho-acoustic phenomenon called Missing Fundamental that allows users to hear the lowest registers of rich bass sounds, even when it is physically impossible to do so. Nearly all sounds consist of a combination of several frequencies, the lowest of which, the fundamental frequency, is often too low to be produced on portable music devices. DNSe calibrates the other frequencies in a way that enables the ear to believe it is hearing deep bass sounds. The processed bass overtones compel the brain to replace the missing fundamental bass signals, creating the illusion of the low bass registers. In doing so, DNSe enables portable music devices with earphones or small speakers to simulate the acoustic depth that could only be achieved with more sophisticated equipment.
为了突破这种局限，DNSe运用了一种名为基频缺失的心理声学现象，就算在物理上不可能做到，都能使用户听到丰富低音中最低的音域。几乎所有的声音都是由多种频率的结合组成的，其中最低的，也就是基频，常常因为太低以至于不能在便携式音乐设备上还原。DNSe以校准另一频率的方式，使耳朵相信听到的是重低音。这种经过处理的低音能暗示大脑制造重低音的错觉来替代丢失的基频信号。通过这么做，DNSe让使用耳机或小型扬声器的便携式音乐设备模拟出那种只能在更高端设备上得到的低沉的声音。
4.< High Fidelity Sound > < 高保真音乐效果 >
Digital music files(MP3, WMA, AAC, and etc.) are mostly compressed from their original recordings by information-lossy process for more memory efficiency.
数字音频文件(MP3, WMA, AAC, and etc.) 为了更多的记忆效能，大部分是经过有损处理后，从原始唱片压缩而来的。
Though these compression formats are based on very sophisticated psycho acoustic theories and claim that they can carry equivalent high fidelity sound as compact discs do, many audiofiles and musicians still complain that there is perceivable degradation of sound, especially in high frequency range. This situation becomes even worse as the compression gain increases.
虽然这些压缩格式是建立在非常复杂的心理声学原理基础上，并且声称能够带来和CD相等的高保真音乐效果，但是许多音频文件和音乐家仍然抱怨有可被察觉的音质降低，尤其在高频范围。这种情况在压缩增益提升的时候变得更加糟糕。
DNSe Audio Upscaler detects the bandwidth of the incoming audio stream and automatically recreates the missing frequency components to make full-banded higher fidelity sound.
DNSe Audio Upscaler（提高音质）能发现这个音频流的带宽，并且自动还原这个丢失的频率部分，用来营造全频段更高保真度的音乐效果。
下面这段内容留到下一篇“玩转DNSe3.0”里再解释，与本篇没多少联系。
5.< Design Your Acoustic Experience >
DNSe incorporates embedded technologies that tweak the sound in order to optimize the desired sound image. Using different formulations of technologies, Samsung has created numerous preset settings that enable you to easily customize your listening experience according to genre of music or other desired acoustic circumstances.
This audio post processing that takes place enables the music players to restore the best sonic experience for the listeners. By reproducing the genuine stereo sound intended by the music contents creators, audio enthusiasts can rest assured that they can listen to optimized acoustics that enhance the type of music they are listening to.
The presets breathe life into the portable music player. They tweak the music so that classical music paints sweeping vistas of sound…as if you are in a concert hall. So that hip hop music blares pulse-pounding bass…as if you’re dancing in the hottest club. Users will be able to conveniently select the preset that makes their music come alive, taking full advantage of all DNSe 3.0 has to offer, and enjoying music as it was meant to be heard.

花了近十个小时才译完的~ 本来以为读懂就能翻译，不会太难。
等到要中英对照着翻译的时候才发现，自己的整句表达能力实在是……
希望能对各位有帮助，起码在看完后明白两点——
1、耳机和组合音响的差别，不仅仅是音质这么简单。声音如果没有经过3D音效的打散，用耳机是永远听不到组合音响的效果的。当然，如果你始终认为与组合音响相比耳机放出来的才是正确、自然、好听的声音，那就当是没看过这篇文章。
2、不要以为耳机的频响范围真如包装上标的那么宽广，20Hz的低音是大部分大单元低音炮都下探不到的频率，一副单元直径不超过5厘米的耳机（更不要说普遍直径1厘米左右的耳塞了）能达到甚至更低的频率，你觉得可能吗？耳机的低音效果不过是模拟出来的。
无损格式的诸多缺点使它难成主流。体积大，而闪存容量很有限，一个4分半的FLAC音频要34MB左右，转成245vbr的MP3只要8.3MB，体积相差4倍多，但用人耳基本不能听出区别；无法加载专辑图片、歌词等歌曲信息；网络资源少，传输速度慢……
如果是放没有立体音效的声音，再好的耳机，再怎么高保真，都没有音质可言（模拟5.1声道的那种除外）。但只要是一副解析不错、不染低音、数据不错的耳机，却不管风格如何，总能用DNSe3.0调出合适的听感。
听了一个多月M1的DNSe3.0，再听P2的DNSe2.0时发现已经不能接受了，即使M1把Concert hall的两段全部调零，听感上也比P2强不是一点点，大概是音频CODEC的原因吧，又或者是DNS3.0比2.0不仅是多了点功能吧，总之科技在进步。
