FLAC (Free Lossless Audio Codec) is the open-source reference implementation of a patent-free lossless audio compression format, comprising libFLAC/libFLAC++ libraries plus the flac and metaflac command-line tools. It compresses digital audio without any quality loss and supports tagging, cover art, seeking, and Ogg FLAC container embedding.
Use cases
- compress wav files to flac losslessly
- decode flac files back to wav
- rip cds to flac
- edit flac metadata tags from the command line
- add flac encoding support to my application
- convert audio to a lossless format for archiving music
- embed flac in an ogg container
- verify integrity of flac files
When to choose
- you need lossless audio compression with no quality loss
- you want a patent-free, open format with a well-documented API
- you need fast encoding/decoding with wide player and device support
- you want to embed FLAC support in software via libFLAC or libFLAC++
When to avoid
- you need lossy compression for maximum size savings (use MP3, Opus, or Vorbis)
- you need a pure GUI converter rather than libraries and CLI tools
- you need compression of non-audio data (use a general-purpose compressor like zstd)
