Open the files and follow the installation procedures.

The Processor plugin will be placed in a folder according to the path below, unless you have made changes during the installation process:

  • Windows
    • Program Files/Common Files/VST2
    • Program Files/Common Files/VST3

Start your DAW and locate the audio plugin in the plugin menu. You might need to go through additional steps to activate the plugin, depending on your DAW.

Log in to your Dirac account if not already signed in.

There will be no filter stored in the audio plugin unless you have previously created new filters with the calibration tool.

Press the “play” button in your DAW to ensure that the audio stream is active while connected with the calibration tool. It is important that the audio stream is active during the whole calibration process. Here is a 30 minutes mp3 that you can use.

  • Make sure that your computer is connected to the internet for licensing purposes.
  • Please see to that your calibration microphone is connected to the computer running Dirac Live.
