Excellent blog. Easy to follow step by step instructions which seem to be absent from every other site dealing with Creating Digital Music. Would like to se.e more info on codecs.

Well, Chris (or anyone else), looking at the updated docs, are there any areas in particular you’d like addressed? (Especially since some of the people involved at Apple may be reading!)

Oh, dear. You’re right. I stopped reading when I came to that sentence, because I was like “why should I care, then?” It is just poorly worded. Okay, back to the flip-flop factory.

“wherein it goes in to some detail about the fact that there is no information about programming AudioUnit Effects, which it even says are the most common form of AudioUnits. We found this dripping with irony, considering there are only really two types of AUs, and there isnÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢t much different in the architecture between the two.”

I think is says:”Nor does this version provide instruction on developing types of audio units other than the most common type, effect units.”

Notice the the “other than”…..

People seem ready to diss without even reading this document carefully. And there are more than two types on AUs.

So it sounds like going UB was a success! Great!

Have they improved the documentation? Look at the first page of the “guide,” wherein it goes in to some detail about the fact that there is no information about programming AudioUnit Effects, which it even says are the most common form of AudioUnits. We found this dripping with irony, considering there are only really two types of AUs, and there isn’t much different in the architecture between the two.

It is, in short, useless, like almost all Apple documentation about AudioUnits. We’re still left with trial-and-error for most things. For a company that does both AU and VST, the guide actually points you in the wrong direction on several counts, chiefly in the area of GUIs.

As for switching to UB, the hardest thing for us was actually buying Intel Macs. It was simply a matter of recompiling, and a little bit of trial and error to find the build style that worked correctly on both platforms. It took all of four hours to do our first UB.
