First:
Yes the much vaunted and long awaited CoreAudio SDK 1.4.2 is now
avaiable; http://developer.apple.com/audio
The SDK readme contains a list of the changes (which are quite
extensive) in this SDK, including the addition of several new
examples covering everything from an example AU Instrument
(SinSynth), "SimpleSDK" = a place to get you started, and other goodies.
It also includes fixes to the resources files needed for building
audio units.
As to this read me - it shouldn't have included this comment because
there really is nothing in this file, so we didn't include it in the
SDK.
The main change (and this is detailed in the SDK's Readme file is the
following:
In your Project's settings you need to add the following to the
OTHER_REZ_FLAGS:
-d ppc_$ppc -d i386_$i386
What this line does is then use the settings you make elsewhere in
XCode (whether to build ppc/i386 or both) to also decide which
version of the resource needs to be built for the AU.
The other change that accompanies this is the AUResource.r file. This
file now uses those defines to make the above determination. This
file is also now used both by the AudioCodec and AudioFileComponent
examples as well (so you can build universal versions of these).
Sorry for the oversight.

ps - there is also a link for the CoreAudio SDK 1.3.6 - this is a
simple revision to the 1.3.5 SDK that allows it to be installed on a
Jaguar system. We won't be updating the 1.3.x SDK any further, but
will keep it available for download as it has some sources that are
no longer available in the 1.4 and beyond SDKs
We urge AU developers to move their AU development over to the 1.4.x
SDK as it contains a number of fixes. An AU built with this SDK will
still continue to work on both Jaguar and Panther systems.

but I can't find any such file...
thanks,
