Question before even trying: In my understanding if you don't operate a DAW, the DIRAC equalization is system-wide in Windows? If so, can it be quickly switched on/off?
My use case would be to use "DIRAC live for studio" for my HTPC, to fine-tune the FR of my monitors. Output via USB to RME ADI2-DAC. So far so simple, but the HTPC is also one of the sources for a completely separate 5.1.2 system (via HDMI) and (via the RME) for headphones. Obviously, I want the DIRAC correction only for the monitors, so I have to be able to switch it on/off.
