The FLAC format is specified at https://xiph.org/flac/format.html but work is underway to further clarify the document and publish it as an IETF RFC. The current draft can be found at https://datatracker.ietf.org/doc/draft-ietf-cellar-flac/ A FLAC-in-MP4 encapsulation specification can be found at https://github.com/xiph/flac/blob/master/doc/isoflac.txt

Open question before we move forward with this is the following:

The carriage spec https://github.com/xiph/flac/blob/master/doc/isoflac.txt is in the draft stage Version 0.0.4 (draft) it would be very valuable if the referenced specification moves to a stable stage.

Suggested change
FLAC,"<a href='https://xiph.org/flac/'>FLAC</a> Free Lossless Audio Codec. Encapsulation of FLAC in ISO Base Media File Format"
FLAC,"<a href='https://xiph.org/flac/format.html'>FLAC (Free Lossless Audio Codec) format and encapsulation specifications</a>"

The page suggested above now links to all FLAC-related specifications.

Furthermore, the draft designation has just been removed from the isoflac.txt file, I have just confirmed with one of the people involved in writing it that this is OK.
