X Code 3.2.5 / AU Lab 2.2 Now Available – Caveat Emptor

Here’s a pretty tech oriented post for those of you who have been using AU LAB for an audio unit host.

For those of you using AU Lab – the new X code 3.2.5 update is now available – which includes an update in AU Lab to version 2.2.

I did the update this weekend – and couldn’t get AU lab to work for the life of me.  If you’re using a newer mac – you might have better luck – but I was unable to get audio routing to the channel and the program would crash when trying to open a new document.

Based on the release notes I was able to see – the biggest update to the software was an automatic aggregate device configuration.  Which I don’t really get as setting up an aggregate device in Audio MIDI set up is well documented.

That may be the issue with the problems I had but in the meantime I had to go back and install the previous X code version over 3.2.5 to get a working version of AU Lab.

Like I said – You may have better luck if your system is more up to date.  Here’s what I’m running (note: I running 32 bit instead of 64 bit).

Special Note:

This suggestion only involves not using Software Update to install the new X code tools.  If you want to install the rest of the tools and skip AU lab – you’ll have to do it manually

  1. just follow the directions below
  2. choose X Code 3.2.5 instead of 3.2.2
  3. When down downloading choose Custom Install and install what you need

What to do if you DO need to re-install AU-Lab

Re-installing AU lab is not as straight forward as you might think.  There are probably multiple ways to  do it – but this is what worked for me.

While there are a series of paid subscriptions – you can sign up for the Apple Developer Program for free.  This will give to access to previous versions of X code tools (which has AU lab as a component).

Once you register and get to the login screen: Look for a screen called Downloads and Programmer Assets.

Then look for Developer tools.  If you scroll down you’ll see X code 3.2.2 Developer’s Tools – which has version 2.1 of AU Lab.

“Xcode 3.2.2 Developer Tools

The download will take a while.  Just do the full install and it will replace the old files.

While not a very elegant solution it is a functional one.

I hope this helps!
