I think to answer this question, we first need to figure out what is lossy and lossless music.<\/p>\n

First of all, it should be noted that the lossless music we talk about is often lossy in theory. Because the music recording is converted into an audio file, it must be converted, and there must be data loss in the process of digitizing audio, so in fact, the lossless we usually say is actually lossy.<\/p>\n
So what do we generally mean by lossless and lossy?<\/p>\n
Lossless refers to “lossless sound format data”, which compresses only the amount of data, but not the quality of the sound. Compared to lossless audio, lossy audio loses some information. It is mainly compressed by reducing the audio sample rate and bit rate, and the output audio file will be smaller than the original file.<\/p>\n
So what does lossy audio lose? Lossy audio mainly loses the high-frequency part of the audio. Theoretically, the hearing range of the human ear is 20~20000HZ, but in fact, each person’s hearing range is different. Some people may have a hearing range of 20~19000HZ, which is sensitive to high frequencies. Others may have a hearing range of 20~16000HZ. It is not sensitive to high frequency sounds and is completely inaudible after a certain frequency.<\/p>\n","protected":false},"excerpt":{"rendered":"
