Changes listed are relative to the latest public stable release.


  • Faster filter export on most devices.

  1. Right-click on This PC in Windows Explorer and select "Properties".

  2. Click the "Advanced system settings" link.

  3. Open the "Advanced" tab.

  4. Click the "Environment Variables..." button.

  5. Click the "New..." button under "User variables for <username>"

  6. Enter the following:


    • Variable value: OFF

  7. Click "OK".

  8. Restart the Dirac Live application and verify that it is possible to complete a calibration.

Disable Exclusive Mode by either deleting the environment variable or by setting its value to "ON"


  • Fixed the known problem where some NAD and other devices didn't populate the subwoofer filter unless using version 3.4.4 or older.

  • Fixed the known problem where some NAD devices got substantially louder sound with Dirac ON than with Dirac OFF.

  • Fixed a problem when a general and misleading error message was displayed when trying to enable Dirac filters while being in measurement mode.

  • Fixed a problem that blocked the app window from being moved while being busy with background operations.

  • Fixed a UI glitch that exposed Windows-style title-bar buttons also in MacOS systems.

  • Fixed an issue that could cause the app to stall after a failed login attempt.

Known problems

  • Filter export to devices from Onkyo/Integra/Pioneer take longer time than usual.
