The essential difference and sound quality difference between MP3 and lossless (flac.APE)...
The most common format everyone listens to now is probably MP3 (according to the survey, 90% of They are listening to MP3. This includes those who use professional players, mobile phones, computers, etc. to listen to music, and 7% of them listen to small format music such as ogg and aac, while only 3% listen to flac. , APE and other lossless music), few people listen to lossless music. A large part of the reason is that current portable players have too little support for lossless formats. Even if such products exist, they are often expensive and prohibitive.
There are many people who still don’t know about lossless music, or even haven’t heard of it (many of my friends are like this). Today I will briefly introduce the current mainstream music formats. .
When people record the singer's singing into the original file of digital music, the music file at this time is very large, which is inconvenient to store, so people compress it. Now it is almost popular All digital music formats are compressed, such as MP3.aac.ogg. Including flac.APE, etc., but their respective compression and encoding methods are different. What we often call lossless (flac.APE) is lossless compression. The previous small formats such as MP3 are lossy compression.
Lossless compression is like flattening a piece of bread. The volume becomes smaller, but the quality remains unchanged. In fact, most of the sounds we record are inaudible to our human ears because the frequency is too high or too low (some animals such as bats and dogs can hear part of it). If we can't hear it, what are we still doing? So we delete this part of the inaudible sound data, and the remaining part of the music data that can be heard by human ears will become very small and easy to store. This compression method is called lossy compression (such as MP3) .
So what is the difference in sound quality between lossless and lossy?
Have you ever had this experience? For the same song, we play an MP3 and a flac, and then listen to it with headphones, but we can’t find any difference in sound quality! But if you listen to MP3 all day and listen to lossless all day, it will be a different feeling! Listening to MP3s for a whole day makes your ears easily tired, but listening to lossless music is not a big problem (as long as you don’t fall asleep, haha)!
What causes this? This is what I’m talking about today about the difference in sound quality between lossless and lossy! We know that music has rhythm, and there are differences between rhythms. For example, no matter how fast or slow the song is between treble and bass, it will always have an excess. The characteristic of lossless music is that no matter how fast or slow the song is, it will be excessive. Whether there is sound or not (regardless of whether we can hear it or not), its data always flows smoothly, making the magnetic vibration in your headphones smooth and the sound emitted natural and real; while MP3 and other lossy formats lose the ability to hear the human ear. Part of the data is missing, so the magnet in your earphones vibrates unnaturally, causing it to vibrate when there is sound but not vibrate when there is no sound. In this way, the magnet vibrates excessively and is unstable, producing glitchy noise. You may not be able to hear it, but Listening to music for a long time will make your ears uncomfortable (of course, some good headphones can also avoid this glitching sound, but most motor oils cannot be purchased)!
People often laugh at those music enthusiasts. Please note that listening to music is not guilty, but having a fever is justified! Those who listen to lossless music may not necessarily have a fever, but those who have a fever will definitely listen to lossless music!
