老实说,现在的大多数DSD都是用老文件转录或者转换来的。并非原生录制的dsd。
如果制作来源差的话,别说dsd256,就算是dsd1024也是一坨便便 但是如果是真正原生录制成DSD的,效果自然很好,越高的码率,意味着音乐制作成本越高。至于哪种够用,你应该去关注销售dsd文件的公司,更多采用的是什么码率 |

耳朵特性都不一样,这玩意儿要看自己能不能听出来差,别问别人有什么用吗。

没必要研究这个,有兴趣就搞256或者升频,没有十分的兴趣就听听dsd64,pcm24/96,16/44.1可以了。

有人根据手头一堆叫不出规格的初级器材 :
测试方法 三台播放器ー两套音响 三台播放器ー同轴解码器ー两套音响 电脑ーusb解码器ー两套音响/耳机 nas(linux系统)ーusb解码器ー两套音响/耳机 安卓手机ーusb解码器ー耳机 去听偏爱的某小姐各种格式的音频,再去断言高码率音频超出人耳听觉范围,有次声,说DSD128及以上完全没必要 ,见其言论: 理论上24bit96khz母带录音已经超过人耳的听力范围,dsd64录音取样相当于24bit117khz,dsd128-512完全没必要。 即使录音回放器材支持人耳听力范围外的频率,次声波和超声波谁受得了? 只是说明知识贫乏而已,去哪里拷贝一堆资料也证明不了什么。 |

关于更高bitrate的好处:
The reason we generate these additional delivery formats and DSD bitrates is to provide customers purchasing alternatives tailored to their DAC's design capabilities. It is correct that there's no additional music content information contained in the higher DSD bitrate deliverables from the original DSD bitrate. What's different is the uncorrelated modulation noise content placement in the frequency spectrum. When a DSD original file is converted to DXD (PCM), the inherent DSD modulation noise is removed through the decimation filtering, and reoccurs when modulated back to DSD. The modulation noise (again, uncorrelated) is the carrier part of the DSD bitstream modulation, and an inherent part of the DSD bit stream. Improved Phase Response While the modulation envelope spectral shape is the same regardless of the DSD bitrate, its effective frequency start and end points move an octave higher for every doubling of the DSD bitrate. For DSD64, the uncorrelated modulation noise is about -110dB at 20KHz, rising to about -50dB at 100KHz. For DSD512, the modulation noise is about -110dB at 160KHz, and -50dB at 800KHz. This allows the customer's DAC to use gentler, more Gaussian shaped reconstruction filter algorithms, with far improved phase response, yielding a more analog sounding, more spacious and detailed playback. 本帖由IOS客户端发布 |

关于DSD64以上版本的来历,NativeDSD是这么说的:
NativeDSD sells only recordings that were originally recorded in DSD or DXD (352.8KHz PCM). With the exception described below, the overwhelming majority of these recordings were edited and post processed in DXD, then converted (modulated) into one or more DSD deliverable bit rates by the label. NativeDSD acquires the label's original DXD edited master, and using Merging Technologies Album Publishing, create first generation DSD64, DSD128, and DSD256, as well as a DXD FLAC deliverables. Additionally, on selected recordings, a 32bit PCM WAV file is extracted (the DXD PCM FLAC is 24 bits by format definition), and uses it to modulate a DSD512 using HQPlayer Pro. Exception The exception to the above are the few label recordings (Yarlung, Eudora, Just Listen etc.) that record in DSD, and do no PCM post process mixing, level balancing, or EQ etc. That's achieved by restricting post processing to just editing where, if there were edits, only the edit transition interval (typically 100ms or less) is PCM converted, leaving the DSD music content unaltered when published. For these recordings, the DSD edited master (the actual recording master) is used with HQPlayer Pro to re-modulate and create the missing DSD bitrates. 本帖由IOS客户端发布 |

达10G一专辑的DSD256要求PC硬件;软件非常高, 不容易搞好, 我这里DSD128甩DSD64几个马位

比较过索尼HY-RES商城售卖的山形交响乐团莫交全集(DSD64)和久石让指挥的贝交全集(DSD256),没怎么听出差距来,应该是器材还不够档次。但比任何重制模拟时代的老录音效果好的多,这个差距相当明显
