IRDX Studio: Impulse Response Loader by Bogren Digital

A standard impulse response captures the tone and resonance of a cabinet at one moment, so it cannot react to how hard the guitar is played. Bogren Digital says IRDX technology, developed by producer Jens Bogren, uses machine learning to reconstruct the difference between a real cab and an impulse response. The result is meant to add non-linear speaker behavior, so that notes and chords respond more like they would through a real speaker.

The developer describes the effect as subtle at first, and says the difference is most noticeable when comparing engaged and bypassed states. Guitar tones are the main focus of the product.

IRDX Studio's library tools are aimed at producers who work with large IR collections. You can curate favorites, hide duplicates and find recently used IRs. The preview mode lets you hear an IR before loading it, and a dedicated Audition Mode lets you compare IRs without changing your blended sound.

The graphical mixer combines up to five IRs at once. Each mixer slot has its own EQ, phase and resonance controls, so you can shape the blend before it reaches your mix.
