What is music to you? ?Is it entertainment and pastime in daily life, or is it a dream that you constantly strive to pursue? Music reflects human emotions in real life. When you plug in the headphones, it is not only an auditory feast, but also a spiritual memory.
So our choice of sound quality is particularly important, so let’s take a look at the difference between 128k and 320k music.
Identification
When we talk about the quality of sound, we mainly look at three aspects of measuring sound: volume, pitch, timbre, and whether it reaches a certain standard. The volume of the sound is the intensity of the audio; the pitch of the sound is the frequency of the audio; the timbre of the sound is the overtone of the audio. The quality of the audio source depends on the music file format and compression ratio.
1. 128k
The most mainstream music formats at present are MP3 and wma. The MP3 files we usually listen to have a compression rate of 128kbps (normal sound quality), the compression ratio is about 1:10, and the file size is only 4M, achieving a relatively balanced position in terms of size and sound quality.
2. 320k
Generally speaking, the sound quality of MP3 files with a compression ratio of 192kbps is relatively good. If it is compressed to 320kbps (extreme sound quality), the file size It is generally 8M, and the sound quality is very close to that of a CD player. It is difficult for ordinary people to distinguish it, and the feeling of listening to music at the same time will be very good.
Lossless sound quality is the ability to compress the audio file into a smaller size while retaining 100% of all the data of the original file. After restoring the compressed audio file, it can achieve the same sound quality as the source file. size, same bitrate.
Music is a delicate sound that you are accustomed to listening to in the late night, afternoon, early morning, walking, sitting quietly, or working, because it brings empathy, truth, comfort or indulgence, soothing or warmth , and has always been with us in life.
