does ogg vorbis or any other format currently allow say, a whole cd recorded and compressed into one file, but with points stating where one track begins and ends, so you can just play certain songs out of this file, or possibly cut songs out of the file into seperate tracks. or is there any format that will do this in the future? (like ogg vorbis maybe). just wondering, thanks!

The only problem is current lack of tools that do something intelegent with these points. * Encode each track into separate ogg files and concatenate ("chain") all. Just use `cat' (or `copy /b file1+file2 target' on dos). This produces a legal ogg file that plays the whole CD (without gaps!). Then you need a player that can jump to the chain boundaries or a tool that can cut the file on these boundaries. None exist yet but I think both was promised to be created today :). It shouldn't be hard. (The cutting/seeking is all there, just no way yet to tell them `the 3rd boundary' instead of `the 356917th sample'.) * Encode as a single file (or chain at whatever arbitrary points you want), and record the boundary points separately. See http://www.xiph.org/archives/vorbis-dev/200106/0055.html for one proposed way to put it in the vorbis tags. It was not adopted as this is not the most elegat awy to do things but it does work. No automatic tools exist that use such tags either but there are tools that will show to you what are the cut points so you can seek to them in the player or use the existing `vcut' tool to split on this points. Again, it would be easy to add automation for it, e.g. write a script that calls `ogginfo', parses the tags, computes the cut points and calls `vcut' with them. -- Beni Cherniavsky <cben@tx.technion.ac.il> (also scben@t2 in Technion) Best way to lose ~6GB music and other personal files: create a roaming profile on another computer pointing to your My Documents instead of your profile dir; logon - it won't find your settings; so logout - it will be "saving your settings" very long time because it is busy deleting all unrecognized things in your directory.

Hi Andy I can't speak for ogg vorbis but I know of a proprietry format from OTSJuke.com (.OTS files). These contain modified MP3 frames with redundancy removed and supports multiple songs in one file with pointers to each song. They say it can be used to store one CD in one file and keeps things tidy. This may have potential for adding to ogg vorbis in the future if it doesn't already. Ross.

Another important thing is that edges of gapless songs must mend without click or pops (even if there are no gaps at all). Ogg Vorbis is truly magnificent with gapless track because they come out perfectly. :-) <p>Greetz, Aleksandar <p><p><p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.
