I'm looking for a little guidance from the experts on choosing the correct audio manager to use for a project. As I see it, I have the Carbon Sound Manager and CoreAudio to pick from.
My goal is to create a codec for FLAC to allow people to use that format for iTunes and/or include it as the audio track in a movie.
For iTunes to recognize it (e.g. during a drag & drop operation into its window), I apparently need to create a MovieExporter and MovieImporter. There appears to be sufficient sample code to figure this out (though the docs are... difficult). If anyone has a pointer to docs on iTunes codec management, please advise.
During my investigations I've looked at creating a 'sdec' via the old Sound Manager. This would provide the basic functionality for compressing/decompressing the sound file and would make it available as a compression format within QuickTime for a sound track.
However, I've been lurking on this list for quite a while and noticed that CoreAudio will eventually replace Carbon Sound Manager within the QuickTime framework. Therefore, for the sake of future proofing a new project, it appears that the right move is to create an AudioCodec and an AudioConverter in CA. I realize QT doesn't use CA yet, but it sounds as though that change is somewhat imminent (i.e. before the year is out). This is a hobby project for me (I normally work on I/OKit drivers), so there isn't any particular deadline I must adhere to.
What do you recommend? Should I implement this via Carbon Sound Manager and hope it continues to work through the transition to CA? Or should I implement in CA even though QT doesn't use it yet? I am grateful for any and all comments.
