Ah, I didn't know that. Sounds good.
How will the cd writing work on windows? Using cdrdao, too? I'm
asking because I'm having difficulties compiling cdrdao on OS X.
However, OS X shippes with a disc recording framework, which is part
of the system SDK and provides all libs necessary to write CDs. But
it would require a totally different export function, e.g. each track
must be a separate wave file, and I don't know if it supports pre-
gaps at all. (CD-TEXT is supported, thought.) Another option would be
to use the toc-to-cue program shipped with cdrdao, to convert the
output into a cue/bin file, which could be written with any
standalone program.
Now that I think of it, wouldn't it be cleaner to write each track
into a separate wave file anyway? It would have several advantages:
- once we switch to internal cd writing libs, we will probably need
it anyway (at least the framework of OS X requires "track objects",
which can be wave files)
- the wave files can be converted to mp3, written to CD with another
application, re-imported into traverso etc., which is much more
convenient if one file = one track.
The naming scheme could be similar to the toc file name, that is
depending on whether we export the current song or all songs, the
file names could be "SongName-01.wav" or "ProjectName-01.wav", so as
to have consistent names from SongName-01.wav ... SongName-0n.wav or
ProjectName-01.wav ... ProjectName-0n.wav.
What do you think of that idea (and who volunteers ;-) ? I would, but
you are much better coders than I am...)
Greetings
Nic
