The future of speaker modeling

IRDX Technology logo

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.

IRDX speaker VS Impulse Response

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.
