About FLAC and MP3
Understanding when to use FLAC lossless audio versus MP3 compressed audio.
What is FLAC?
FLAC (Free Lossless Audio Codec) stores audio withany quality loss, resulting in large file sizes typically 3-5x bigger than MP3. While perfect for archiving, FLAC files are impractical for portable devices or sharing.
What is MP3?
MP3 (MPEG-1 Audio Layer III) uses lossy compression to produce much smaller file sizes while maintaining good perceptual audio quality. MP3 is universally compatible with every device and audio player.
