Extended Knowledge: FLAC VS MP3

FLAC (Free Lossless Audio Codec) and MP3 (MPEG Audio Layer-3) both work as a popular audio format to play music on different devices. But they are different in 3 ways:

  1. FLAC use lossless compression to keep all the audio information of the original file, nothing is sacrificed; while MP3 use lossy compression to shave off some parts of the music to make it smaller;
  2. FLAC is relatively large in size since it needs to store all the information as the original, while MP3 is smaller in size;
  3. FLAC is a perfect format for CDs, to contain all the details for a professional and pleasant music playing, while MP3 is a standard format to be played on all kinds of players;
  4. Virtually all media players support MP3 file, but not all of them can support playing FLAC files;

So, it is hard to tell if FLAC is better than MP3, it depends on what’s your priority and which device you are using to play the audios.
