About
What is .FLAC?
FLAC is a lossless audio codec that compresses sound without any quality loss. It is widely used for high-resolution audio, archival storage, and music distribution where preserving original fidelity is essential.
History
Origin of FLAC
FLAC (Free Lossless Audio Codec) was developed by the xiph.Org Foundation and released in 2001 as an open, royalty-free format for high-fidelity audio compression. Unlike lossy formats such as MP3 or AAC, FLAC preserves 100% of the original audio data while still reducing file size by 30–60%. Its openness, transparency, and strong metadata support made it a standard for audiophiles, archival institutions, and digital music distribution.
