An update to QT for Panther will include some pieces from CA that QT needs to run on pre-Tiger systems. This subset is essentially defined by the CA API as it ships on Panther at this stage. However, we don't keep a separate branch for Tiger/Panther, so once you run a QT Panther update, you will have the Tiger versions of those CA pieces that are already on Panther.

For instance, the AUEventListener API in AudioToolbox/ AudioUnitUtilities.h would then update to be the same as what we ship on Tiger.

So, if an API is available on Panther already, with a QT update, that API will then have the same functionality as it does on Tiger.

New CA APIs, and new components are by and large only available with Tiger.

Does CoreAudio have a version number associated with it? What version is now
current with 10.3, and what version is coming with Tiger? How can I check
what version is on a computer?


Will the Tiger version just announced be available for 10.3? Will it come
through a Quicktime7 update again?


Finally, last year it was indicated that the new CA will have File Reader
Audio Units built in. Is that correct, and if so is there documentation
available that describes the capabilities and use of the Units? (will we be
able to dispense with the AudioFile-new sample projects and get those
capabilities straight from the File AUs?)
