Bogren Digital's IRDX Core is a guitar amp simulation plug-in that enhances amp simulators by recreating the behavior of real cabinets that dynamically respond to the input signal. It's 41% off, now at $23.

Bring your guitar amp sim and cabinet impulse responses to life. Simply add IRDX Core after your guitar amp or IR loader plug-in and discover the natural movement, 3D feel, slightly jagged edges, and unpredictability that you could only get by recording a real guitar cabinet at high volume with a microphone.

This is not an IR loader

IRDX Core is a unique plug-in. It doesn't load impulse responses, but instead you can place it after an amp sim or IR loader to add natural-sounding speaker dynamics that you can only get by playing a big speaker cabinet at incredibly loud volumes.

What's wrong with impulse responses?

A well-crafted IR is essential to getting a great guitar amp sound on your computer.

However, all IRs have significant limitations. It can only capture a static, linear image of the tone curve and cabinet resonance. Like a photograph, so to speak.

Real guitar speakers, on the other hand, are living, moving objects that dynamically respond to the input signal.

Speakers are non-linear, and it is that non-linearity that IRDX faithfully emulates and adds to your amp sim or IR loader.

How do I use IRDX Core?

In your major DAW, launch the IRDX Core plugin in an insert slot right after your IR loader plugin or guitar amp simulation that contains your speaker cabinet model.

IRDX Core can be used to enhance such plugins, except those from Bogren Digital. This is because all amp sim plugins already have IRDX technology built in, so there is no need to add IRDX Core afterwards.

Other brands of IR loaders and guitar amp plugins will sound better with IRDX Core.

Input Calibration

In most cases, no adjustments in the IRDX Core plugin are needed.

If you want to make sure IRDX Core responds in the most natural way, you can use the automatic input calibration, which listens to your guitar signal and ensures you get a healthy input level.

Choose your style

IRDX Core comes with two different modes: "Normal" and "Intense".

"Normal" mode gives you subtle and natural speaker movement, compression and distortion.

"Intense" mode gives you a slightly different flavor and makes these effects more noticeable. Listen and choose the one that best suits your music.

The IRDX difference

Like tape saturation, the IRDX effect may seem subtle at first. However, as you go back and forth between enabling and bypassing, you'll notice:

With IRDX Core disabled, every stroke on the guitar sounds similar and the guitar seems somehow two-dimensional and lifeless.
With IRDX enabled, the differences between individual strokes become more apparent and you get all the changes over time that are so important to wake up your sound and capture the listener's attention.

Using IRDX Core in a mixing situation adds width, movement and excitement to your guitar tracks. It also helps your guitar blend better with other instruments.

With IRDX Core enabled, your guitar sound will respond more realistically to your playing as you play your amp sim in real time.

The Future of Speaker Modeling

IRDX (Impulse Response Dynamix) technology brings your guitar sound to life by adding dynamic, true-to-life speaker behavior to static impulse responses.

Developed by producer Jens Bogren, IRDX technology uses advanced machine learning techniques to reconstruct the differences between real cabs and impulse responses.

The result is a guitar amp sim that responds like a real amp, fits easily into a mix without sounding stale, and feels great to play.

Impulse responses are great at capturing the tone and resonance of a guitar cabinet, but they're essentially just a static snapshot in time.

The impulse response itself has the sonic characteristics of a real cabinet, but without dynamics it produces a lifeless, fatiguing sound.

Real guitar speakers respond dynamically to the input from the amplifier. They displace, compress, and break down air depending on how hard they are pushed by the amp.
