Theoretically, the difference is huge, but ordinary users may not feel it, but enthusiasts can experience it.

The bit rate of traditional CD is 1411Kbps, while the highest bit rate of common MP3 files is 320Kbps. The bitrate of MP3 is almost one-fifth that of CD.

MP3 uses MPEG Audio Layer 3 technology to compress music into files with a smaller capacity at a compression rate of 1:10 or even 1:12. In other words, it can achieve very little loss in sound quality. In this case, compress the file to a smaller extent. And it also maintains the original sound quality very well. It is precisely because of the small size and high sound quality of MP3 that the MP3 format has become almost synonymous with online music. The MP3 format of music per minute is only about 1MB in size, so each song is only 3-4 megabytes in size. Use an MP3 player to decompress (decode) MP3 files in real time, so that high-quality MP3 music can be played.

Lossless music uses lossless compression, which can compress the audio file into a smaller size while preserving 100% of all data in the original file. After restoring the compressed audio file, it can Achieve the same size and the same bitrate as the source file.

The following is a detailed explanation of MP3 and lossless music from Baidu Encyclopedia for reference.
