SACD已经可以被抓出dsd层？

最近在闲逛hdbits网站时发现居然有几张sacd的dsd部分的声轨种子。点进去发现好像sacd的dsd层貌似已经可以抓出来了。现在正在下载中，好像用foobar就可以播放。种子中的关于dsd抓轨的描述是如下：
This is the new era of SACD ripping.

In the past we have only been able to rip SACDs by recording the multichannel analog outs of an SACD player and into our analog sound cards. Many people have used horrible Creative Audigy cards, and quality has been disappointing at best. Other rips that we have seen have been nicer, using the best that analog sound cards can offer from the likes of M-audio, Lynx, etc. However, quality has still suffered due to the multitude of problems that arise with analog capturing in general. Unless the SACD player used for the transfer is a very expensive one, the analog transfer quality will leave a lot to be desired.

But we now can celebrate in a new "standard" for SACD ripping. We can now capture a pure 24-bit PCM digital signal which is converted directly from the pure DSD stream from the disc - and this is achieved by using a special "modifed" SACD player. These modified players been around ever since the SACD format has, but they have always been extremely expensive (like, try a $2000 Denon player which you have to order from Switzerland). But things have progressed and a few companies are offering a modified version of the famous Oppo DV-980H player, which is well known for its affordability yet uncompromised quality - especially with regards to digital SACD output!

I have purchased such a player to make this SACD album available to you in the highest quality currently possible. The Oppo offers pure DSD output over HDMI 1.2 but it also gives the option for PCM output. The Oppo internally converts the DSD to PCM at 24-bit/88.2kHz and the "mod" captures this PCM signal and outputs it through three stereo S/PDIF (coaxial) jacks. To capture this glorious digital signal, I am using three M-Audio Delta 1010LT sound cards simultaneously. They each have a single stereo coaxial input, so in order to record all six channels simultanesously, three cards must be used. I'm using Adobe Audition 1.5 in multitrack mode to simultaneously record the 6 channels in real time, then I map the channels with Audition's "multichannel encoder", and export the individual mono wav channels. After that I split the album into the tracks and encode it to MLP with surcode, and author it to DVD-A with Discwelder Chrome. No editing of the audio signal is made in Adobe Audition, this is a straight digital capture of the signal and as close as you can get to copying an SACD disc-to-disc at the present time.

SACD ripping has now been taken to a level never attained before, and I hope that you enjoy the music, the surround/stereo mix and the wonderful audio quality of this album! If you do not have the original SACD and are able to purchase it at a reasonable price, I encourage you to buy it and enjoy the original DSD sound on the disc itself. If not, this is the best alternative way for you to enjoy it.

这算是个大事件吗？还有就是比较好奇的是这样的音轨文件在通过类似int202这样的数字输出到传统dac上能播放吗？如果能播放的话效果怎么样啊？

是的，不過不是真是rip了dsd, 而是已經trans code了的PCM, 因此多少也不是太完美。

即使如此，也算抓轨的一个里程碑式的突破。

这个很不错啊

根据文内内容理解应该是把dsd层降频或者说是trans code到24-bit/88.2kHz规格的pcm进行抓取吧。用的貌似是oppo的播放机？

t1174

好像有一台 denon 也可以，而且可能出到96/24.不過要在內部mod.

neverwinter

这是个好消息

bydrizzen

ESO的机器可以MOD吗……

。。。。。。。貌似现在全世界能直接播放dsd母带的没几台机子？ls的好像可以直接播放吧？

tedczj

好像是oppo之类的hdmi输出得到的

sdumj23

好消息

wl336

oppo原来可以用hdmi得到，用pcm 24bit 88kHz已经是有损了。。。

*.dsf文件一直就有了，只是一般家用电脑没法播放而已。有的可以播放也是转换成PCM以后，DSD的优势无法体现。

据了解、、目前还没有能够“完美”解密的。
