What is a .FLAC file?
FLAC is a popular lossless audio format that compresses without losing any quality.
- Did you know
- FLAC was released in 2001 and is the most popular format for lossless music archiving.
- FLAC compresses audio without discarding a single sample, so a decoded file is mathematically identical to the original recording.
- Development was begun by Josh Coalson and the format now lives under the non-profit Xiph.Org Foundation, the same group behind Vorbis and Opus.
- On the web a .FLAC file is served with the MIME type
audio/flac. - Analyser spots a .FLAC file by its signature bytes
