In order to use Dirac Live® Processor plugin, you will need to download and install two different components: the Dirac Live® application (3.0.x) and the Dirac Live® Processor plugin (1.3.x). Dirac Live® is used to measure and generate filters, while the Processor audio plugin stores the corresponding filters and processes audio data. 

Download and Install Dirac Live® Processor plugin

You can download the Dirac Live® Processor plugin here. Make sure that your computer is connected to the internet for licensing purposes.

Open the file and follow the installation procedure.

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


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 you 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.

Download and Install Dirac Live®

You can download the Dirac Live calibration tool (desktop software version) here. Make sure that your computer is connected to the internet for licensing purposes.

Select your device

Dirac Live will start with scanning the network for compatible devices that will store the filters and process audio data (such as AVRs or the Dirac Live processor audio plugin). You can click the “Rescan devices” icon in the upper left corner if you want to refresh the scanning result.

Please select “Dirac Live processor” and proceed. Do not select any AVRs. You want the Dirac Live Processor plugin to function as the device that stores the filters.

Select your recording device

Volume calibration

  1. Place the microphone in the middle of the listening area.
  2. Make sure the master output level is at a low value.
  3. Select a speaker, for instance, front left, and press the “play” button for that speaker. You should now see a sign above the play/stop button that indicates the recording level. If you slowly increase the master output level, you should see the level bar for the selected speaker increases. If not, go back and check the microphone connection.
  4. Increase the master output until either the level bar for the selected speaker is in the green area, or the output level is loud enough at a comfortable level.
  5. When the above process is completed, the level bars for all speakers should indicate roughly the same value within 15dB.

Select arrangement

There are three options available, please select “Studio”.


Potential problems and workarounds during the measurement

Filter Design

Edit target curves of frequency response

After completing the measurements, Dirac Live will automatically generate suggested target curve(s) for frequency response and the corresponding correction filters that are intended to enhance your sound system as much as possible. You can make fine adjustments to your preferences. The frequency response correction will be performed in real time so that you can see the correction result immediately and continuously make more adjustments.

Inspect impulse response correction result

Under “Filter design”, you can switch from “set target” to “impulse response” to view the impulse response correction result. Impulse response affects clarity, detail and all spatial aspects of the sound. Dirac Live’s unique impulse response correction can greatly improve staging, bass and clarity.

There is no need to adjust the impulse response yourself, as Dirac Live automatically optimizes it for the best possible result.

Filter export

The last step is to export the filter for a listening test. Select a slot and save under the desired name (there may be an auto-generated name, which can be replaced). When export is complete, the application will return to the Filter Design view. Remember to save your project before exiting the application.

After the filter is exported, the filter will automatically appear in the audio plugin. No other actions are needed to apply the filter to your audio stream.
