Developing xCode

I've been doing a lot of research on Podcasting and OS X and there are some things we are lacking on the Mac OS X platform. I have never really messed with C++ Programming and to develop this software application that would benefit a lot of podcasters and just people who really dig this.

I could use iTunes or MegaSeg it can do it but it's not really simple and people love simple things. It's kinda been stressing my brainpower having to learn xCode, C++ and using Frameworks mostly Core Audio. Then there is the added problem of learning how to build a Universal Binary for the PPC and Intel platforms on OS X. So we will see where this goes and how it goes.

But my basic question is can anyone recommend a good book for learning xCode and C++ with Carbon and using Frameworks like CoreAudio.
