[Flac-dev] FLAC codec in OS X Leopard

Thanks for the news, Stephen. While I am excited to see Apple
recognize FLAC in their sample code, I do not really see this as a
benefit to FLAC users. Currently, native FLAC is the most popular
format for distribution and legal music downloads. OggFLAC does not
seem to have gained any popularity, despite there seemingly being
more support. I really don't see CAF-FLAC gaining popularity,
either, especially not on WIndows.
CAF is a great format, and I would like to see it replace Broadcast
WAVE. Meanwhile, I will probably compile and installed the FLAC
extensions for CAF. But I'm sure that I'll be stuck with native FLAC
files for my existing and future online music purchases.
What I would really like to see - and this is not a new request in
our community by any means - is Quicktime and iTunes support for
native FLAC. I believe that there is an existing solution out there
which converts the entire file in memory - but that is useless for me
when many of my FLAC files are 1 to 3 hours in length.
P.S. I do not want to discourage you, Stephen. I am merely stating
my opinion that we need native FLAC support in Mac OS X much more
than we need CAF-FLAC support.

Although I was a bit disappointed, but not surprised, to see that
FLAC support isn't built natively into the OS, I was very happy to
notice recently that Apple ships source code for a FLAC encoder and
decoder codec component in /Developer/Examples/CoreAudio/AudioCodecs/
All that is necessary to build the codec is to download the latest
FLAC source code, copy it into the project tree, #define VERSION
appropriately, and build it. Once installed this allows Core Audio
aware applications to encode and decode FLAC in a CAF container. I
think this is superior to the XiphQT components because it doesn't
require any external frameworks to be installed, and it allows
encoding. I've posted a screenshot of QuickTime's standard audio
configuration dialog at http://img49.imageshack.us/img49/5231/

I think a great next step would be to write an AudioFileComponent to
add native FLAC file support. An AudioFile component coupled with
the FLAC codec component would automatically bring native FLAC
support to any Core Audio-enabled application!
Apple's license for the sample code allows it to be distributed in
source or binary form- it would be trivial to package up the compiled
codec for redistribution, if people feel that's something worth doing.
