不能硬接DTS的详细说明

我们都说外置解码器的性能优于内置解码器，你为啥死顶着要声卡解码？

写的真乱   搞不明白lz要什么。。

我说说我使用的情况，看看能不能帮到LZ，光纤或者同轴连接功放，XFI选择数字输出（声卡不解码）,软件输出选择SPDIF ，功放就能收到对应的DTS或者AC3信号。

声卡解码，只能模拟了输出了，
要声卡解码还是用光钎，多声道在光钎上通过？光钎可没那么强大{lol:]

0 o  p& F: k9 x9 Q声卡有光纤的吧？我的播放器是KMPLAYER，用的解码是完美解码2008，一般用的片源的声源是AC3和DTS声轨。
在KMPLAYER播放器按“F2”进入设置界面。“滤镜控制”－》“解码器使用”－》“内部音频解码器”－》“常规”－》“AC3 扬声器”选SPDIF－》“DTS 扬声器”选SPDIF。到“外部音频解码器”－》“AC3 音频”选项，点右边那个“C”设置按钮－》出现“Filter Info”界面－》在Main标签上 output format 选项中选中“3/2 + SW5.1 channels”在 Use SPDIF 选项前面的勾打上，点“确定”退出，在“DTS 音频”上也是照AC3的设置一样。点“确定”退出。在“自定义滤镜管理器”选项中选中“添加夷注册的滤镜”，在“Directshow滤镜”选项中选中“AC3 Filter”点“确定”就可以了，保存后退出重新启动播放器，开光纤输出到带解码的功放上面就可以纯光纤输出给功放硬解码了。这个是我的个人经验，在XP 和 VISTA上面都是一样的。
; U- p! V5 M9 m) r8 _% y还有一点最重要的，输出的采样率一样要固定在“48K”上面，不然是行不通的。

1) Pass the AC3/DTS signal to a external decoder.
5 A$ d8 J4 a' c+ c, QThis is where your optical/coax connection is used.  To go down this route, you must first have a set of speakers or a decoder that supports Dolby Digital.  In your DVD software, select 'SPDIF' as the audio output method and 'SPDIF Pass-through' in your soundcard options.  What this does is tells both the software and soundcard to leave the audio from the DVD in compressed form and send it straight through the digital outputs.  Your digital speakers/receiver will do all the decoding to give you full surround sound.  Please note that this is the only way to get 6 channels through an optical/coax cable.

2) Decode the AC3/DTS with your Sound Blaster.
2 U# D. j$ K7 l2 NYou should choose this option if you don't have an external decoder.  In the DVD software, select 'SPDIF' as the audio output method and make sure that 'SPDIF Pass-through' in the souncard options is off.  The DVD software will now pass the compressed audio to your soundcard, which will then decode the data.  The soundcard will output the 6 channels using the analogue connections (or digital DIN, more on this later).  If you try to use a digital optical/coax connection to your speakers, you will only hear faint sounds from the front left/right speakers.

3) Decode the AC3/DTS with software.
$ Q! [- o; [: }4 MIf you have a soundcard that doesn't support Dolby Digital (like the SB Live! 24-bit) and you don't have digital speakers, the only way for you to get surround sound in movies is to use software to decode the AC3/DTS.  The free versions of DVD software you get with hardware often don't support this feature,  you will most likely need a full version.  First select 'Dolby Digital' or 'DTS' decoding in the DVD software audio options (you must select the right sound format for the movie you are watching).  Then make sure that 'SPDIF Pass-through' in the soundcard options is off.  As with method (2) you must connect your speakers with the 3 analogue cables, not optical/coax.

这是创新论坛转过来的,看来的确不行,以后有机会搞模拟的试试

图片全是X 且 我现在用5700解码器 用的数字输出 为什么解码器的DTS解码灯就不亮呢 谁能指点下？

图片改过n次,有兄弟推荐个外链地址固定的相册吗,用了雅虎网易都不行,原来用的要收费了.....................
