audio unit undeclared indentifier

Question

Im trying to use code from these 2 links (pretty much the same LINK1 LINK2). But neither work even with the second link being an apple prog guide.

Like I said the actual error is "use of undeclared identifier" on many of the data types. To keep this a little shorter I will just show the top 2 data types.

 AudioComponentInstance audioUnit;
 AudioComponentDescription desc;

From the searching I have done these should be this which says they are in the AudioUnit framework. AudioUnit.framework is added to my "link binarys with libraries" so I dont understand why these data types are not found.

I have tried , and with "" instead of <> but no luck. Other frameworks I have used I have not had to do this. So I'm not sure if its really needed. — owen gerig, May 10 '12 at 16:16
you can put it in your .pch file to include it everywhere or just in one particular .h or .m, but it is needed — hooleyhoop, May 10 '12 at 16:35

Per the comments above i was not importing the header. I needed to add

#import <AudioUnit/AudioUnit.h>
