Setting Up “Testing Environments” Or Multi Layered Tones In AU Lab

One site that I always forget to link to and need to do so now is the Guitar Amp Modeling Blog,  which is just a really tremendous resource.  It’s really inspiring to me to see so many people working on pushing more and more into alternate live and studio approaches to guitar.

A couple of days ago I went to the Speaker Cabinet Impulse section of the forum and found that RedWirez, a company that sells a high end collection of speaker impulses is giving away their impulses from a Marshall 1960A with Celestion G12M 25-watt Greenbacks to celebrate their birthday!  The folder is about 107 MB of impulses that go from 44.1 KhZ – 16 bit to 96 KhZ – 24 bit.

There are 17 different types of mikes used for each IR set AND there are ambient mics to capture the back of the cab at various distances, room and wall mics as well. You can go to the link for that here.

I still have the recabinet set – which at $15 for something like 2000 irs is an amazing bargain as well.

But one thing that comes up in something like this is how do you sort through all those speaker sounds?

My solution is to set up a bunch of instances of LA convolver on multiple busses in AU LAB.

In this way I can set up one bus at a time and mute the other channels to be able to a/b/c everything.

Additionally, you can set up more complex sounds by combining different IR’s.

For example here are the IR’s used in bus 1:

and bus1 is the tone.

Here are the IR’s used in bus 2:

and bus2 is the tone.

Here are the IR’s used in bus 3:

and bus3 is the tone.

And the final tone of all 3 together:

To my ears, this creates a more full bodied sound than any one channel.  Each plug in takes up more processing power – so it may be a balancing act based on resources – but since AU LAB uses so much less CPU than something like Logic, it’s easier to pull off here.

In case you’re interested – here’s the patch the sound is based on:
