IRDX Core

We love IRs here at Bogren Digital. Well-made IRs are vital to obtaining a great guitar amp sound on the computer.

But all IRs have a significant limitation: they can only capture a static, linear image of the tone curve and resonances of the cabinet. Like a photograph, if you will.

On the other hand, real-life guitar speakers are living, moving things that respond dynamically to the input signal being fed into them.

Speakers are non-linear, and it’s those non-linearities that IRDX faithfully emulates and adds to your amp sim or IR loader.

In any major DAW, launch the IRDX Core plugin on an insert slot that immediately follows an IR loader plugin or a guitar amp simulation that includes a model of a speaker cab.

You can use IRDX Core to enhance any such plugin — except for the Bogren Digital ones! That’s because all our amp sim plugins already have the IRDX technology built into them, so there’s no need to add IRDX Core after those.

Any other brand’s IR loader or guitar amp plugin will sound better if it’s followed by IRDX Core.

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

If you want to ensure IRDX Core responds in the most natural way, you can use automatic input calibration that will listen to your guitar signal and ensure you get a healthy input level.

IRDX Core comes with two distinct modes - "Normal" and "Intense".

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

The "Intense" mode offers a slightly different flavor and makes these effects more noticeable. Have a listen and pick one that fits your music the best.

Our IRDX (Impulse Response Dynamix) technology breathes life into the guitar sound by adding dynamic and true-to-life speaker behavior to static impulse responses.

IRDX technology, developed by producer Jens Bogren, uses advanced machine learning methods to reconstruct the difference between a real cab and an impulse response.

The end result is a guitar amp sim that reacts like a real amp, easily fits in a mix without sounding stale, and feels great when playing through.

Impulse Responses are excellent at capturing the tonality and resonance of a guitar cabinet, but by nature they are only a static snapshot in time.

By itself, an impulse response has the tonal characteristics of a real cab but without dynamics, it creates a lifeless, fatiguing sound.

Real-life guitar speakers react dynamically to the input from the amplifier. They move air, compress, and break up depending on how hard they are being pushed by the amp.
