For those of you willing to implement easily a simple “room curve” in Roon, you can use this calculator (Excel file). This is originally not from me, credits go to Jim the Oldbie on miniDSP forum.
You have to provide 3 numbers:
- low limit in Hertz,
- high limit in Hertz,
- overall dB attenuation (should be a negative number).
Then simply copy/paste the filter parameters in Roon PEQ and you’re good to go!
