Chapter marks in audio files

I know AAC is capable of having chapter marks for audiobooks and podcasts, but what about other formats? I can't find too much on this subject... there seems to be an open-source MP3 chapter project, but I guess most players don't support it (which do, though? I'd really like to know). What about Ogg Vorbis, does that have anything for built-in chapters?

Thanks in advance.

EDIT: And what about Matroska audio? That supports pretty much everything, right? How would you go about setting that up?

There's always cue sheets and APL files, but it seems that we may need to know your intentions before being able to suggest appropriate options.

Are you using foobar?  Lossy or lossless?  Why not AAC?
I'm on a horse.

jarvolt, I have used chapters with Matroska audio.  In my case, I took a 5.1 LPCM file from a Blu-ray concert disc, compressed it to FLAC, and muxed the FLAC file to Matroska (.mka) and then was able to use the chapters file added to the .mka file to seek around within it as well as later split the file.  For DVD and Blu-ray sources anyway, chapters in matroska files are very easy to use.  For CDs, I think you're still better off with cue sheets.

The ogg container also supports chapters, btw.

At one point (and this may be technically incorrect, I'm not sure) I took a chapters file in DVD Decrypter's OGG chapters format and converted it to a cue sheet by coyping over minutes and seconds and coverting milliseconds in the chapters file to CDDA frames in the cue sheet.  That worked pretty easily to produce a cue sheet that I could then use with foobar2000 to seek/split FLAC files made from sources other than CDs.

Is there any reason why you can't break the file up in an audio editor (Audacity?) and save the lumps out as separate files per chapter in LAME MP3 to play back gaplessly?

Cheers, Slipstreem.

Okay, that would probably be what I would prefer, then. Is there a simple way to add chapter marks to Ogg files? And what players support them?

The only reason I ask is because I want to help out these people who offer essentially a podcast in MP3 and OGG, and the chapters would be really useful.

AVI-Mux GUI will do it.  I'm not sure whether it allows the import of pre-existing chapters for OGG as well as MKV, but definitely supports muxing chapters to an OGG file.  Media Player Classic on Windows does ogg chapters.  I'm not familiar enough with many other players to verify their support, but since OGG/OGM are open source one would imagine that VLC and MPlayer also support OGG chapters.

AFAIK, the ID3 specification has been able to support chapters for some time.

ID3v2-chapters-1.0 - ID3.org

But I do not yet know of any player or tag editor which supports it. If anyone could point me in the direction of one, I'd be a happy chappy.
