FLAC (Free Lossless Audio Codec) is an open-source lossless audio compression format developed by Xiph.Org and released in 2001. Unlike MP3 or AAC, FLAC preserves every bit of the original audio data, allowing perfect reconstruction of the source. Compression typically reduces file size by 40–60% compared to uncompressed WAV or AIFF. FLAC supports up to 32-bit sample depth and 655 kHz sampling rate, as well as embedded metadata tags and cover art. It is royalty-free and widely supported on Android, Linux, Windows, and macOS, as well as media players including VLC, foobar2000, Audacity, and most hi-fi audio hardware.
