Now that we can load custom IR’s inside Blue Cat’s Axiom (Amp + internal EQ), we thought it was a good idea to write a short tutorial on how to load and use/tweak IR’s inside Blue Cat Audio software.
You don’t know what an IR is? IR stands for “Impulse Response”, and is the reaction of a dynamic system in response to a brief input signal (usually a very short audio signal = gun shot). This allows to make a digital print of hardware or software and load the result in your own host software.
We can use this procedure to record models of reverbs, equalizers, amplifiers, cabinets, … In our case we’ll going to use it to load IR’s of existing guitar amp cabinets in the POST EQ section of Axiom’s amp simulator (Destructor). All you need for this is Blue Cat’s Axiom or Destructor and some impulse responses of guitar or bass amp cabinets. We are going to use here the free (& huge) 7deadlysins Impulse Pack gathered by Osiris Guitar.
Step 1: Load Axiom (or Destructor)
Step 5: Click on “Load IR” and load an IR. We’re going to use the “Engl 4×12 V30 SM57 Between03” IR from the free 7deadlysins Impulse Pack. Note: you can also drag and drop the files directly from the File Explorer or Finder onto the module.
Step 6: Here is the result with the IR loaded, and now the real fun begins! What is great is that you can use all the existing tools from the EQ module (HP, Shelv, Peak, LP, Comb Filter) and fine tweak your IRs further, so you’ll end up with tons of possibilities.
Of course the new IR tool is not limited to the Post Filter: you could for example load IR’s of guitar pickups in the Pre Filter or transform an EQ module into a reverb using reverb impulse responses.
