A few days ago, it was reported that NetEase Cloud Music has launched Hi-Res (High Resolution Audio, high resolution music) sound quality, but it is still in the grayscale test stage, and it is expected to be fully promoted in the future. According to relevant sources, the Hi-Res sound quality of NetEase Cloud Music will be the exclusive privilege of members, in addition, the capacity of singles under this sound quality will be greater than 30MB, which is 5 to 10 times that of traditional MP3.
It is understood that the sampling rate of digital music indicates the amount of information stored in audio, such as the ordinary CD sound quality sample rate of 44.1KHz/16bit, that is, it refers to the equal interval of 44100 samples of the signal in one second, and each sample saves 16bit (bit) data, and theoretically the higher the sampling rate, the better the music quality. It is reported that the Hi-Res music sample rate is much higher than the CD audio, so Hi-Res will also retain more data for the master.
In fact, with the improvement of users' requirements for music quality, many related platforms have successively launched Hi-Res sound quality in recent years. Previously, in August last year, Kugou Music opened up audition of Hi-Res sound quality, and the Hi-Res music library was opened for the first time with a scale of 3 million songs. It is understood that the bit depth of its Hi-Res audio reaches 24bit. Shortly after, QQ Music also launched Hi-Res sound quality, and supported songs will be marked with the word "Hi-Res" in the lower left corner.
