I add an update.
I have include the path search for the header file into my project settings. That solves the problem of not finding the headers.
However I still have 198 errors.
Here what happened:
Building target “MyPlayer” of project “MyPlayer” with configuration “Debug” — (198 errors, 9 warnings)
        cd /Users/gabry/Documents/Apps/MyPlayer
    setenv PATH "/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin:/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin"

Other hundreds of line...
Any clue?

Thanks.

Ok,
sorry for not providing enough info.
The CAAudioFileStreamer.h doesn't compile with 517 errors. I don't believe I have to past all of them.  ;-)
Now the reasons of so many errors is because it cannot find many others file (headers and implementation) for other classes.
So the question now change and I ask did you include all the files .h and .ccp that CAAudioFIleStremer needs in you application? There is any way to tell the compiler "go and search for this files"?
Thanks.

Can anyone please send me a list of basic operation I have to do in my Audio Unit Render call back function. The only example Apple provides is MixMash but I don't understand how I can make a buffer list from my file audio file. I try to use CAAudioFileStreamer.h but it does not compile to me.

If you want specific answers, you need give more specific information.
For example: What errors do you get compiling CAAudioFileStreamer? (Copy and paste the error messages.)
You really should try to use that code instead of figuring out how to implement the same functionality from scratch.
