Problem with DIRAC Live 3.x AU plugin

Hello All, Hello Damien,

I use Audirvana and Dirac for years with success.
Dirac AU plugin works fine if I use a direct connection to my DAC (USB, Devialet Air via Wifi), specially with real time plugin configuration that appears in its window. But if I choose a direct UPNP connection also proposed by Audirvana with the same DAC, there is no AU plugin applied nor real time configuration window. No AU use possible with UPNP. Is this normal ?

I’m on Catalina and use a Devialet gear, with Dirac Live for Studio (3.x)

Hello @Inox,

You can use Audio Unit plugin in Audirvana in UPnP, you need to select it and set it up before you play your music. Have you tried with one of the Apple Audio Unit?

For me Dirac only works in Realtime mode. No idea why. Realtime is not possible via unpnp and therefore Dirac does not work.

Which version of the plugin are you using?

At the changelog of the Dirac processor I just see that I need to update.
After the update of the processor it works. Also on OSX
Perfect. Thanks.

Dirac Live Processor v1.3.12 Changelog


  • Can now be used without realtime control in the host Audirvana on Windows

Hi All,
I’m using the latest version of Dirac Live Processor (1.3.15). I found what was wrong : if the “real time configuration” box is checked, no plugin is applied with UPNP. When unchecked, correction is applied.
Thanks Damien.
