Dirac Live for NAD Devices

Great recording and production studios understand that exceptional loudspeakers don’t guarantee exceptional audio. Room acoustics are the weakest link in most sound systems, making acoustic sound treatment a must. Dirac’s sound optimization suite includes digital room correction in order to help your loudspeakers reach their full potential in any listening room. Download Dirac Live for macOS or Windows. Also available on App Store and Google Play.
