So I have had a bit of fun trying the low / high shelf filters lately . Have had Roon for years but hadn’t bothered until now and I can see that these features help fine tune my system by ear.
My question is how can I get a reading to actually measure and show any problems ? . Rather than just having a guess how can I get a graph of my In Room frequency response and relative volumes so I know what to correct.
You can use a USB microphone and software (REW, Acourate etc) to capture a frequency distribution. You can then correct it manually with PEQ or generate a wav file to convolve. See these threads:
This article in the KB may assist with convolution in Roon.
Last week I tried a simple method to correct for my room characteristics using Roon DSP with really satisfying result:
What I did:
find an album on Qobuz or Tidal with sample recordings of frequencies. E.g. from 30 Hz to 150 Hz in steps of 5 Hz. There are several test albums out there. Higher frequencies will not need room correction.
Test every frequency track just by listening on your regular listening spot. Play the tracks one by one via Roon.
You will probably experience difference in ‘volume’ between frequencies. Most likely there is one frequency (or 1, 2 or 3 subsequent frequencies) which is annoyingly pronounced compared to others. This could well be caused by your room.
Correct this by using the Parametric EQ in the Roon DSP: insert the frequency that you have found, insert a gain of appr. -8 dB, insert a Q-factor of 10.
Select EQ Type: “Peak/dip”.
Re-listen to all frequencies and find the result of the correction. All low frequencies should have the same comfortable level for your ears.
And of course listen to music to see if there is an improvement.
