The room optimization software improves sound quality when listening to a hifi system with your computer. It can be used by the non-technical user as well as the audio engineer. The technology behind it, Dirac Live®, is a result of years of research. This advanced digital signal processing algorithm is used in high-end AVRs, in luxury car sound systems such as Rolls Royce, BMW and Bentley and also in digital cinema theaters.

The room correction program consists of two software applications:
1. Dirac Live Calibration Tool
The calibration tool will show you step by step how to measure and analyze the degradations that your loudspeakers and room imposes on the sound. Correction data is generated automatically. The room calibration tool requires a microphone for the measurements and works with standard and USB sound cards (DAC:s). If you are non-technical just take the measurements and the software figures out the rest! As an advanced user, you can edit the target frequency response in great detail. Recommended sound calibration microphones for the measurements.

2. Dirac Audio Processor

This application lets you apply the created correction data to all sound that is played from your computer, regardless of media player or application.

The room correction software supports up to 24 bit resolution at 192 kHz sample rate. The technology is unique in that it corrects not only the frequency response but also the impulse response. This is in contrast to the common minimum-phase room correction systems that do not optimize the impulse response. Correcting the impulse response yields improvements in the stereo image, clarity and transient reproduction of the music.
