学习了!其中1、2、4、5非常清楚,很好理解,不愧是行业会员。
关于3中的“真·DSD只有一种制作方式”,还想多问两句,因为涉及到以后是否购买某些所谓的“原生”DSD:
1、模拟母带直接用带有DSD输出的ADC直接采样,应该会带来跟原版(比如原版CD)不一样的听感吧?因为DSD用的ADC和原版CD用的ADC可能不是一台。在这种不同听感的情况下,应该如何取舍,买原版还是买新版DSD呢?
2、一些网站,比如Native DSD,号称是DSD直录的,我很好奇这是怎么做到的?因为DSD基本没有办法后期处理,这些直录的DSD就是艺术家们一次性录音的,没有任何处理?
补充,我之前查到一篇Native DSD的文章,Tom Caulfield写的(他好像也是业界权威,似乎还拿过2012年格莱美奖,和2018年格莱美奖提名,都是最佳专辑工程奖?)。他在大家质疑Native DSD专辑的真实性的时候,写了这么2段话(特别是红字部分),很有意思:
“The stated objective of nativedsd.com is to offer those recordings originally recorded in DSD format. We've further expanded that to PCM recordings (DXD) that are recorded natively to the release format.”
“DSD rendering however precludes all Mix functions. Only level changes are supported. Labels that desire to sweeten their projects in post, in Pyramix, must have the entire project converted to DXD (352.8KHx 32 bit PCM), then converted back to DSD. That's normal for studio projects, and the exception for acoustic music from the labels we offer.”
后面还补充DSD只能做的两种编辑:
"1. a butt splice which butts together the end of one time point in a take to the beginning of the next selected, and discards the data (time) in between. There are no sample/bit rate conversions involved.
2. A crossfade (VERY common) between two time periods within a take, or takes, where the crossfade interval (milliseconds to tenth's of a second) is a DXD product. Either side of the crossfade is untouched DSD."
我个人感觉,他的意思就是,DSD后期编辑几乎不可能。所以我们把DSD -> DXD (352.8KHx 32 bit PCM) -> DSD 这种编辑过程,也归类到原生DSD中。
这个其实应该算是作弊吧?DSD -> DXD (352.8KHx 32 bit PCM) 这一步,应该是有损的转换吧?
