1. First of all, you must distinguish the difference between music score and audio. Music score is composed of text notes, while audio is music that can be heard. Audio is played or sung according to the format on the music score. The music scores can be the same, MP3 and FLAC are both audio files;

2. MP3 and FLAC are both audio files, but the compression is different. MP3 is lossy compression, FLAC audio is lossless compression, sound spectrum They are all the same, but the quality of the music is different. MP3 quality is slightly worse, and FLAC is lossless audio.

(1) Commonly seen MP3, WMA, and OGG are called lossy compression. As the name suggests, compression means reducing the audio sampling frequency and bit rate, and the output audio file will be smaller than the original file; that is, frames will be lost during compression;

(2), another type of audio compression is called lossless compression. That is, after the compressed audio file is restored, it can achieve the same size and the same bit rate as the source file. The audio formats for lossless compression include APE, FLAC, WavPack, LPAC, etc.

In summary, mp3 The music score is the same as the flac music score. In terms of sound, flac is lossless audio, and MP3 is lossy audio. If the MP3 sound quality is high, it is usually not audible. If the MP3 sound quality is low, it is clearly audible. Good sound quality sounds good. The feeling is different.
