1, different timbres.
DSD music source is rich in details, especially the high frequency part. The timbre of lossless music retains the original details of the sound.
2. Different sizes
The storage space of DSD is almost four times that of CD. Lossless music files are larger than MP3 files.
3. Different characteristics
DSD music is a direct bit stream digital coding. The format of lossless music data itself is PCM or compressed format.
Advantages of DSD coding
1, excellent dynamic range
After the DSD signal is processed by the high-frequency noise shaping circuit, the high-frequency noise of DSD is raised to a frequency that is inaudible to human ears. In the frequency range of 0~20kHz, the dynamic range of DSD on theoretical data is as high as 150db.
2. Small music capacity
DSD coding also has some advantages in storage capacity. With the improvement of sound quality, the file size of PCM music can be said to increase exponentially. However, due to the coding advantage of DSD, the file capacity of DSD is only slightly higher than that of PCM music at 24/96kHz at the standard sampling frequency of 2.8224MHz.
