Audio Codec...
In the panther SDK we also provided a 'smac' component.. this is a
Sound Mgr sdec/scom (both for encode and decode) that turns around and
talks to its Audio Codec... Thus, this is a bridging mechanism that
will allow you to develop Audio Codecs but still have them work in a
QuickTime world (while it is still on the SoundMgr) And of course the
advantage of doing an Audio Codec is:
(1) It appears to any client using an Audio Converter
(2) It will also appear in a QT world when it moves over to CA
I'm also pretty sure (but we've not tried this yet of course, so please
stay in touch with us) that we'll also be able to filter out your
'smac' component and not show it from CoreAudio's Audio Format APIs or
Audio Converter APIs when what we're really looking for there is the
Audio Codec version.... Please make sure you talk to me first before
you ship your codec so I can make sure that our code will do the right
thing for your code :)
You should find that it is measurably simpler to write an Audio Codec
than a SndMgr codec (and you can also do of course higher sample rates
and more than 2 channels) -

If you write an AudioCodec, the AudioConverter will take advantage of
it automatically.
