FLAC stands for Free Lossless Audio Codec, a file format abbreviation.

Open, royalty-free audio format that compresses audio without any loss of quality, typically to 50 to 70 percent of the original size. Audiophiles and download stores use it for CD-quality and high-resolution music.

Example: Bandcamp lets me download the album in FLAC, so I get CD quality in smaller files.

Usage notes

Josh Coalson released FLAC 1.0 in 2001, and the Xiph.Org Foundation has hosted it since 2003. Decoding a FLAC file reproduces the original samples bit for bit, unlike MP3 or AAC. Windows 10, Android and iOS 11 added native playback. It supports up to 32-bit samples and multichannel audio, with metadata stored in Vorbis comment tags. Pronounced "flack".
