What's the meaning of Hi Res when listening to music? Is there any difference between hi res and lossless

With the continuous development of the Internet, various devices have been upgraded, and many functions have also been improved. For example, the quality of music has been greatly upgraded. Sometimes Hi Res music will appear when we hear it. What is the meaning of this, and what is the difference between lossless music and lossless music?

What does Hi Res music mean

HiFi is a word that I believe all friends who have a little knowledge of audio have heard. The full name of HiFi is High Fidelity, which means "High Fidelity". In short, it is a playback sound that is highly similar to the original sound.

However, HiFi has no indicators and can only be described as "close to the original sound" and "closer to the original sound".

The full name of Hi Res is High Resolution Audio, also known as High Resolution Audio. It is a high quality audio product design standard proposed and defined by Sony and formulated by JAS (Japan Audio Association) and CEA (Consumer Electronics Association).

The purpose of Hi Res audio is to express the ultimate music quality and reproduction of the original sound, so as to get a real feeling of the on-site atmosphere of the original singer or performer in the live performance. There is resolution to measure the image recorded by digital signal. The higher the resolution, the clearer the image will be. Similarly, digital audio also has its "resolution".

What is the difference between ordinary nondestructive testing and HR

In terms of the specific difference in the sense of hearing, the first impression of people who have just come into contact with HR is that HR is quieter than ordinary nondestructive players, but the difference will become more and more obvious after listening to it with a nondestructive player that can explain their differences, HR has a larger sound field than ordinary lossless sound field. The environment is quieter and more peaceful. It is not as noisy and exciting as ordinary lossless sound. All kinds of sounds are clear and distinct. They are not mixed together like ordinary lossless sound. Besides, all kinds of sounds are clean and smooth without procrastination. All details are clearer than ordinary lossless sound.

It was once said that this is the relationship between the brain and the body (I hinted to myself that I felt good and then made the sense of hearing subjective), but I personally think it is not. To be honest, HR has really improved a lot more than ordinary lossless, making listening to music more enjoyable. The following two pictures show the spectrum comparison between ordinary lossless and HR. You can see that the HR at 15-20kHz is more than - 80dB, while the HR at the front of the green line in the middle is more sparse. Although it seems that there is no big difference in the picture, their difference is just these details, and the spectrum further proves that there are indeed differences between them.

Hi Res music is actually a pursuit of music quality, so many people who like listening to music will pursue these. I hope the above article can help people in need.
