The encoder then tries to find a good mathematical approximation of the block, either by fitting a simple polynomial, or through general linear predictive coding. If the audio contains multiple channels, each channel is encoded separately as a subblock. In the first stage, the input audio is split into blocks. The FLAC encoding algorithm consists of multiple stages. FLAC uses Vorbis comments for textual metadata like track title and artist name. It may also contain other information, the album cover for example. Properties like the sample rate and the number of channels are always contained in the metadata. The data block contains the audio information. The rest of the header contains the number of samples, position of the frame, channel assignment, and optionally the sample rate and bit depth. A frame header begins with a sync word, used to identify the beginning of a valid frame. Each frame is encoded independent of each other. The encoded audio is divided into frames, which consists of a header, a data block, and a CRC16 checksum. File structure Ī FLAC file consists of the magic number fLaC, metadata, and encoded audio. Design įLAC is a lossless encoding of linear pulse-code modulation data. In 2019, FLAC was proposed as an IETF standard. Version 1.3.0 was released on, at which point development was moved to the git repository. is home to other free compression formats such as Vorbis, Theora, Speex and Opus. On 29 January 2003, the Xiph.Org Foundation and the FLAC project announced the incorporation of FLAC under the banner. Version 1.0 was released on 20 July 2001. The bitstream format was frozen when FLAC entered beta stage with the release of version 0.5 of the reference implementation on 15 January 2001. FLAC has support for metadata tagging, album cover art, and fast seeking.ĭevelopment was started in 2000 by Josh Coalson. Digital audio compressed by FLAC's algorithm can typically be reduced to between 50 and 70 percent of its original size and decompresses to an identical copy of the original audio data.įLAC is an open format with royalty-free licensing and a reference implementation which is free software.
