iRC Impulse Response Correction

Don't let your room hold your sound system back!

Impulse Response Correction

Every room has problems:

  • Parallel walls and irregular shapes cause reflections
  • Bricks, windows and other surfaces cause absorption and reflections
  • Furniture can cause acoustic absorption and reflections
  • Speaker placement can cause timing delays and phase issues

The results are a reduced soundstage, balance problems, and a build-up of bass frequencies.

iRC Impluse Response Correction, based on advanced technology by Dirac, brings these under control. The result is a more focused soundstage with improved phase coherence, bringing more realism and natural sound to your music.

The iRC Measure application uses a calibration microphone (not included) to analyze your room, build an acoustic model to detect defects, and automatically create filters.


Take control of your domain with iRC (Impulse Response Correction), a cost-effective and more flexible alternative to unsightly baffles, diffusers and other room treatments.
