    That's what I am looking for as well.

    I'm using Soundflower (2 channel) and an app called Loopback. Working fine so far. Here is how it's done:

    1 - Set Soundflower to be output audio device for system (Spotify/Youtube etc.)

    2 -Open UAD Console and go to "Settings" then the "I/O Matrix" tab.

    Check where your VIRTUAL 1 and VIRTUAL 2 Outputs are here. Mine are on CH 21 and 22:

    3 - Next, open "Applications" folder, then "Utilities" folder, and open "Audio Midi Setup" and select "Universal Audio Thunderbolt" from the list of devices.

    Click "Configure speakers..." button in bottom right.

    Set "Left Front" to "VIRTUAL 1" and "Right Front" to "VIRTUAL 2"

    4 - Open Sonarworks and set Audio Device to "Soundflower (2ch)".

    5 - Open the "Loopback" app.

    The first virtual device you want to create is:

    Source: Soundflower (2ch) - Delete the "Pass-Thru" source that may automatically be there - you ONLY want Soundflower (2ch).

    Monitor: Sonarworks Systemwide


    6 - Next, go down to "+ New Virtual Device" and click this.

    This second device needs to be:

    Source: Reference 4 Systemwide (select from running applications) - again, delete the "Pass-Thru" source that may automatically be there.

    Monitor: Add "Universal Audio Thunderbolt" audio device.

    Next, click on the connecting blue lines from Channels 1 & 2 in the "Output Channels" section and click the "Delete" button to get rid of them.

    Instead, you want to add new connections from Output Channels 1 & 2 to Channel 21 and 22 of Universal Audio Thunderbolt (or wherever your VIRTUAL 1 and VIRTUAL 2 channels are in your UAD I/O Settings.


    Hey Presto! System audio routed through Sonarworks Reference 4 Systemwide, then back through VIRTUAL channels within console, and now you can send system sound to headphone mixes, use UAD plugins across system sound etc.

    Now what this allows you to do is to add another device as an input (Universal Audio Thunderbolt) and route signals from that to Sonarworks alongside system sounds.

    You could add a connection from Input 1, to output Channel 1 and Channel 2, and these would feed Sonarworks.

    You would not have fader level control from console, or panning, but you could monitor through systemwide.

    I'm not sure on the latency involved. Just installed it all so brainstorming here.

    Loopback is Mac only. But you can still set up Sonarworks Reference 4 to measure room frequency on a PC with a UAD interface.

    I was setting up with the system/versions below. 

    • UAD Apollo x8
    • Sonarworks XREF 20 mic on XLR 3 
    • Windows 10
    • ProTools 2020.3 

    In the Apollo Console for LINE3, enable 48v phantom power and set channel output to LINE3 with Mirror To Monitor OFF.

    In ProTools check that I/O is using the UAD and that MIC/LINE3 is set up.

    Still in ProTools create a new test session with a single mono track - with input as MIC/LINE3, output to MON L/R. Enable Trackinput Monitor. Mute the track. My setup below also has a Master fader but that is probably not necessary. Both tracks are at Unity (0 dB).

    Run the the Sonarworks Reference 4 Measure application and work through the steps.

    When you get to the Select your input and output device

    • mic should be UAD MIC/LINE3
    • 'tap the microphone lightly ' should show signal in the level meter (in both Apollo Console and Pro Tools) but you should _not_ hear anything in your Monitors
    • output should be UAD MON L & MON R
    • 'play test track' should result in sound in your Monitors [Adjust the level with the Console main Monitor dial at bottom right if necessary].

    When you get to the 'adjust the mic input gain on your audio interface' stage, do any necessary adjustments on the Console LINE3 input. I had to increase mine from the default 10dB to 21dB.

    Thereafter the measurement process should proceed smoothly.
