Room correction with Roon

[alec_eiffel (Rémi)]

I assume you know this link which describe a simple method for room correction with Roon using RTA.

• In REW, what values do you use for EQ > Filter Tasks > Match Range? I’ve seen a tutorial with 20Hz to 20kHz being used whereas others say only go up to 300Hz.

Well, it depends if you want to correct the full range or only bass. If mids/highs look ok when it’s better not to correct than to correct. If possible in the mid/highs try to apply the same correction to both speakers to preserve imaging.

@wilro15

Do you define a house curve in REW or in Roon’s DSP? I suppose doing it in Roon makes it easier to tweak later? In that way REW can try to achieve the flat curve.

Important: REW’s house curve is only used to set the target correction, and is not an actual correction. My personal preference is to implement the house curve in REW. This post can help to calculate filter parameters.

• Do you use the Convolution engine or manually apply EQ using PEQ (Parametric EQ)?

I am using the convolution engine as it’s exhausting to copy all parameters in Roon DSP, especially since Roon 1.6 (nice UI for DSP overall, but PEQ s*cks). I have ran some test and the outcome is strictly equivalent between REW generated convolution file and Roon PEQ implementation. Convolution is more costly in terms of processing but usually not an issue.

In REW, what values do you use for EQ > Filter Tasks > Individual/Overall Max Boost? I understand that boosting nulls is a no-no, but do you do any boosting at all?

Moderation is de rigueur. I never go above 4dB.

@wilro15

What value do you have for EQ > Target Level? I chose the auto “Set Target Level” and it came to 83.3. This seems much higher than the 75 others get.

Well it all depends on the level of your recorded sweep! Don’t bother. 83dB is a bit loud for an acoustic measure, maybe try to stay between 75 and 80dB.
