This statement may mean that the MP3 format is a lossy compressed audio file. If the bit rate is too low, there will be distortion and the sound quality will be poor.
Generally speaking, the sound quality is basically good if it is above 128Kb/s, and even better if it is above 192Kb/s. If you are pursuing the best sound quality, you can choose VBR method to compress MP3 files.
