What is the difference between MP3 and lossless sound quality?
Now, many people think that it is impossible to listen to MP3, so they search for lossless music everywhere on the Internet.
So what is the difference between lossless music and MP3? What about the various lossless music formats?
A few days ago, a friend of mine bought a Porsche sports car and then came to ask me for lossless sound quality music. I told him there was no need to play MP3s, but people weren’t happy. The sound in the car was fine. Playing MP3 is a loss of audio.
Now there are many music websites that give lossless to the myth, but do you know what lossless is? What is the difference between lossless music and ordinary MP3? Today I come to talk to you about those things that have no losses.
I remember when Apple held the Iphone4 conference, it came up with a definition: retina display. In short, it has been replaced by a high resolution screen with pixels that exceed the recognition limit of the human eye since the Iphone4. I must say that Mr. Qiao’s trick is very good, he defines a word that everyone can accept and makes Apple mobile phones sell all over the world.
However, the same concept is much older in the world of acoustics. Sound is a type of energy wave. After the experimental research of countless generations of ancestors, it is believed that 40 kHz is a value that can well restore the sound heard by the human ear. Later, for various commercial reasons, some record companies defined the sample rate of CDs at 44.1 kHz, which they considered to be the “retina display” that the ears could hear. Later, 44.1 kHz brought innumerable problems to subsequent generations, because it is not an integer and cannot be divided and multiplied simply by performing SRC sampling, so early Inter defined the output sample rate of the sound card as 48 kHz to save problem. , which creates a sample rate conversion problem that all sound engineers hate
