Impulse Responses, or IRs as they are more commonly known, are a great way to tailor your guitar sounds in our DAW. Used alongside a guitar amp simulator, they can really open up your guitar’s sound and also make the whole sound more realistic in terms of faithfully modelling a guitar played over a real amp.
Impulse Responses can save you a lot of headaches with EQ, compression and effects. It means you can have a virtual amp cabinet collection without having to fill your house with 4x12s. Plus, you can always crank a virtual
The idea is that you can add these ‘sampled’ guitar cabinets to your collection of virtual amplifiers and thus shape the tonality of the whole virtual rig. As you probably all realise, a Marshall 4×12 in a large cabinet has a completely different tone to either a 1×12 open back cab or a 4×10 closed cab, for example.

So, by downloading some free Impulse Responses you can really have some fun making virtual rigs. Nowadays you can load Impulse Responses straight into your virtual guitar amp plugins, as many have a section for doing just this. It’s a relatively easy process and allows you to really experiment with your tones.
If your virtual amp of choice does not have anywhere to load up your IRs then the trick is to use a convolution reverb plugin, as they use the same technology just for reverbs. Load your virtual cab IR into the reverb plugin and set the dry signal to 0% and the wet to 100%. This is not a perfect substitute, however it will work and allow you to add virtual cabs to your virtual amp sims. Of course, you should make sure the reverb plugin is placed after the guitar amp sim in your DAWs effects chain. So instead of a reverb being applied to the guitar amp, you are placing a virtual guitar cabinet to the sound instead.
I have included a link below for NadIR, which is a free plugin made by Ignite Amps especially made just for loading IRs into your DAW.

You can also use IRs with real guitar amps as well, you just need to use a ‘load box’ to take your guitar amps output and then plug it into your DAW. A load box can take an output, i.e. the ‘load’, and turn it into an audio signal that a sound interface can accept.In this video, I’ll be talking about how a guitar speaker cabinet can be simulated using software. This modeling can be done in several different ways.
One very simple way is to treat the speaker cabinet as a spectral processor modeled by an EQ curve. In this case, a simple equalizer rolls off some of the lows, rolls off some of the highs, and boosts some of the mid-range.
Using an impulse response will result in a much more realistic sound to the cabinet. Some companies have taken the idea of an impulse response a step further by modeling not only the cabinet and the microphone, but also the signal that goes through the microphone into a console, and the console is set up to tailor and tweak the sound of the cabinet and microphone pair.
How To Create Guitar Amp Impulse Responses
This extra pre-processing means that these impulses can be dropped into your session. They’re ready to go, you don’t have to do any extra work to get it to sound great.
I’ll be showing you a side by side comparison of these different types of modeling techniques by playing you audio examples, and you can compare and contrast and judge for yourself.
First up, I have a clean rhythm guitar part played on a Strat. I’ll be using Amplitube as my basic amp sim software in this case. I’ll start out by showing you the stock guitar cabinet that comes with Amplitube, but then on a separate track, I’ve got the same exact preamp with Amplitube, but I’ve bypassed the stock cabinet. Then I’m feeding that signal into Recabinet over here. This is a software that can be used to convolve an impulse response.

I’ll start out by showing you the stock impulse responses that come with Recabinet. These have no extra pre-processing. They’re a very raw sound.
Then, I’ve also got setup another track over here, where I’m using impulse responses that come from the Rosen digital studio guitar impulse library. These impulses have been pre-processed, so they’re ready to go and sound great without any extra work.
Here, for the amp sim software, I’m going to be using Guitar Rig. I’ve set up here a Plexi amp so that it has a little more overdrive. Then I’m going to feed that into a couple different ones that you can hear – the stock cabinets, ones the matched cabinet that comes with Guitar Rig, the other is the Control Room pro, and I can fade back and forth between these here.

Then, I’m doing the same thing as before where I’ve got the Guitar Rig here for just the amplifier part, and that’s going to feed into the stock Recabinet here with the stock 1960 Marshall amplifier.
Then I’ve got the Rosen digital. Their pre-processed impulse responses are here. I’ve picked out one I like here with the same Marshall 1960 so you can hear the sound side by side again with the Telecaster.
Last up is a heavy guitar part played on a Les Paul. Here, I’m going to be using Amplitube again. I’ve got an Engl amp going into a Mesa Boogie cabinet.

Then I’m doing the same thing here where I’ve bypassed the cabinet for the amplifier, and I’m feeding Recabinet a version of a Mesa Boogie.
Lastly, I’ve got the Rosen digital. Their impulse response is here for their Mesa Rectifier, so you can hear these side by side.
Hopefully you were able to hear that each one of these cabinets sounds different. In fact, the cabinet contributes significantly to the sound of the simulated guitar amp.

If you’re looking for fast results that sound amazing, definitely check out the Rosen digital studio guitar impulses. I just picked it up, and I was blown away by the results compared to the other cabinet modeling. I hear some really nice fullness, clarity, and definition to the cabinets that they captured. So definitely check those out.

It also eliminates the loud noise generated from a physical speaker which limits your choice of location when it comes to producing music.
To start recording an Impulse Response of your cabinet you will need to have an Amplifier with an Effects Loop, A Soundcard capable of sending and recording a signal simultaneously and a Microphone, so you can hook it up with your computer/DAW and actually get a good signal in and out.

Once you have hooked up everything together with your rig, you are ready to mic up your cabinet and start looking for that “sweet spot”.
Easiest way to do this is have one person playing the guitar with headphones on, hearing the input of the Microphone while giving directions to another person who is moving the Microphone across the cabinet.
Once you finally found the spot you want to record, you will now change around some things in your rig so that the computer can send a signal through your amp/cab and also pick the signal back up using the microphone that you’ve placed earlier.

Now that you have a rig set up and ready for recording and creating an Impulse Response, What you need to do now is download aDeconvolution software so that you can create an Impulse Sweep you will be sending through your cabinet.
The Impulse Sweep is basically sending frequencies through your cabinet from 10hz up to 10khz letting you record how the cabinet reacts to each of the frequencies.
For Mac users that happen to use Logic, there is a native program within the Logic App called Impulse Response Utility that helps you with this exact thing.
Impulse Response Vs Cab Sims + Benefits & Differences
Choose the correct input so that it has the input of the microphone, and the output so that the signal is sent out of your Soundcard and into your amplifier’s Effects Loop.
Choose the channel corresponding to your output regarding the sweep, and switch between the different Test Tones to make sure that they don’t peak the signal and adjust your sweep level accordingly.
You can adjust the length of the sweep, i usually just keep it at around 10 seconds to make sure every frequency gets picked up. The Reverb time should be set as low as possible.

After you’ve recorded your sweep you can trim the recording down by dragging on the visual screen, try and trim away the start until you see where the audio-waves start to form.
Doing this makes it easier to use the Impulse Response you have created together with
