DSD, DFF, DSF, DST Concept Analysis

DSD = direct stream digital; DST = d

DSD is the technical principle. Dsdiff short for DFF is the file suffix DSF is also the file suffix, they mean, but one is the name of Philips, the other is Sony, the file is not compressed, suitable for dual-channel

For multi-channel, because the volume is too large, it is compressed. This is the DST file format. Therefore, dff dsf dst is the same as the file format source code output of DSD technology.

DSD corresponds to pcm dff/DSF corresponds to wav dst corresponds to FLAC

DSD is divided into dsd64 dsd128 according to the sampling rate. The file size is twice different, and the sampling rate is 64 times 128 times of the 44k, respectively. Therefore, it is called a super high sampling rate. However, its bit depth is only 1, while the CD bit depth is 16. Therefore, the comparison between DSD and traditional PCM is meaningless in terms of sampling rate and bit depth. Their technical principles are different.

DSD music was originally released through SACD (supercd, super cd), and only Sony players can play it. Later, in order to be compatible with normal CD, just mix the normal CD data on a single disk, called hybird SACD. In this way, when a Sony player is inserted, the DSD music is played and the normal CD is inserted, play music with normal CD sound quality.

Later, Sony's PS3 was cracked, causing the SACD to be carved out, namely, the SACD rip. The pirated CD is called the SACD-R.

In fact, DSD is a bit embodied in the recording and playing processes, and it is not suitable for digital processing. Therefore, the original recording is recorded by DSD, and then converted to a PCM audio with a high sampling rate for post-processing. Finally, it is released and sold to Cd and SACD carriers with different sound quality.
