WARNING 警告：
Nero 8 won't work for eac3to cause Nero 8 doesn't allow its DirectShow filters to be used from outside of Nero ShowTime. Nero 9 is currently not supported, either. So please use/install Nero 7 if you want to use Nero DirectShow filters in eac3to.
background information 相关背景:
Please note that there are three common problems with "properly" decoding compressed audio tracks. The first problem has to do with that the purpose of a media player is different than the purpose of people like us who want to reencode audio tracks. A media player may want to adjust volume levels to specific parameters and circumstances. We reencoders absolutely want to avoid any processing on the precious audio data. This is a conflict which can not always be solved. The three known problems are:
(1) Some decoders apply DRC (Dynamic Range Compression). Stupidly Dolby's license requests that DRC must be applied, unless your decoder has an option to turn it on/off. Only then the decoder is allowed to not apply DRC. The purpose of DRC is to limit the dynamic range of an audio track, mainly to not annoy neighbours or to accomodate to noisy living room conditions. For our purposes DRC is catastrophic.
(2) Some decoders forcefully downconvert to 16bit, or raise volume for unknown reasons or do other stupid stuff.
(3) Some decoders don't make use of the full available information, but just extract and decode the "core" of the compressed audio data, which obviously results in less than optimal audio quality.
evaluation of available decoders 可用解码器评价:
The Sonic (E-)AC3 decoder forcefully applies DRC. As a result I do not recommend to use the Sonic (E-)AC3 decoder. The current version of the Sonic TrueHD decoder doesn't work properly at all. The Sonic DTS decoder is very good for DTS, DTS-ES, DTS-96/24, DTS-HD Master Audio and DTS-HD High Resolution tracks. The only problem is that it decodes DTS-HD 7.1 tracks only as 5.1. Most DTS-ES and DTS-HD Master Audio 6.1 tracks are fully decoded as 6.1, though. The Nero (E-)AC3 and Nero TrueHD decoders are working perfectly fine, but are limited to 5.1 channels. The Nero DTS decoder ignores the additional DTS-HD information and only decodes the DTS core. The Cyberlink decoders always only output 16bit and can't be used outside of PowerDVD. So they currently do not make a lot of sense for eac3to. The libav/ffmpeg (E-)AC3 and DTS decoders work really well, but the output is not 100% identical to the Dolby/DTS reference decoders. I'm not sure whether there's a difference in audio quality. Decide for yourself. The libav/ffmpeg (E-)AC3 and DTS decoders are both limited to 5.1. Furthermore the DTS decoder ignores the additional DTS-HD information. The libav/ffmpeg TrueHD decoder works perfectly fine including full 7.1 decoding. The ArcSoft DTS decoder seems to be perfect for DTS and DTS-HD decoding. It supports every format and channel configuration that exists including 6.1 and 7.1. The ArcSoft TrueHD and ArcSoft (E-)AC3 decoders are currently not supported by eac3to. （能看懂吗？需要IsaacZ翻译请举手）
default decoders used by eac3to:
eac3to使用的缺省解码器：
MP1, MP2, MP3: libav/ffmpg
(E-)AC3: Nero
AAC: Nero
TrueHD: libav/ffmpeg
DTS(-HD): ArcSoft
making the ArcSoft DTS decoder work in eac3to:
怎样使 ArcSoft DTS 在eac3to 中工作：
Sometimes the ArcSoft DTS decoder doesn't work even after you've installed the full retail software. This can usually be fixed by manually adding the ArcSoft "Bin" folder (e.g. "C:\Program Files\Common Files\ArcSoft\Bin") to your environment path. If you don't know how to do this, google "environment path".
有时即使安装了完整零售版的ArcSoft软件，ArcSoft DTS 解码器仍然无法在 eac3to 中正常工作。这一般可以通过手工将 ArcSoft 的“Bin”文件夹 (如 "C:\Program Files\Common Files\ArcSoft\Bin") 添加到系统环境变量，设置方法请点此查看。
仍然有大段的英文，先凑合着看。 版主真是认真，效率也挺高，这么快就整理齐全了。 看不懂呀，楼主，问一下：

是不是说，我想把dts转成ac3的话，必须有nero呀？ 回复 3# jordan_ch
不是。
只要求有NERO的解码器，而不一定安装NERO。很多通用编解码包都自带NERO的解码器。

eac3to可以把wav转成he AAC？ 学习了，不错，谢谢。
