What is a FLAC file?
FLAC compresses audio without throwing anything away: decode it and you get exactly the original. Files are about half the size of WAV. It is the favourite format for CD rips and hi-res music downloads.
FLAC is mainly used for CD rips, hi-res music and archiving. It plays on Android, Windows 10 and later, recent iPhones (Files app), VLC and hi-fi streamers; older iTunes and some car stereos do not.
