I messed up the .doc-file, so here's the plain text:
Implementation of “CD-in-Matroska”
1. The Lead-In may contain metadata
-fLAC reportedly ditched implementing this for some reason.
1.2. ISRC (International Standard Recording Code)
-The ISRC Code (International Standard Recording Code) is a unique
international identifier for tracks on sound and music-video recordings. The
ISRC is 12 character alpha-numeric code, which functions as a digital
"fingerprint" for each track, unlike a Universal Product Code which is tied
to the entire disc. In addition, the ISRC remains allocated to a track
regardless of changes in ownership. It is an extremely powerful tool for
royalty collection, administration, and anti-piracy safeguards in the digital
In other words, it may be useless.
2.1. Pregap1 of track 01 may contain a truly hidden2 track
2.2. Pregap of tracks 02-99 may contain false hidden3 tracks
3. Number of entries in TOC
3.1. The number of tracks for a CD is in the inclusive range of TRACK [01-99]
3.2. The number of indices for a TRACK is in the inclusive range of INDEX
-Incomplete implementation, only INDEX [00 – 01] currently
4. A track may contain other datatypes than AUDIO
-Uncertain, the degree to which ripping-tools implement ripping data-tracks is
unknown, and the usefullness of ripping such tracks is also uncertain.
5. Other CD-Audio formats than CDDA, such as SACD, DVD-AUDIO, Dolby Surround
Some feedback on this would be interesting, so
that I can get a feel of which direction you want this to take - a complete
1:1 mapping of the Red Book cd-image, a subset of the metadata based on the
Red Book, or just the bare essentials necessary for playing the audio-file.
