Dear all,
Due to room gain, I need to reduce/attenuate level of 5db over a frequency range from 60Hz to 150Hz. I looked at the different options but did not find the right one allowing to do that…
Can you please help? Should I combine a Low Pass / High Pass?
Thanks
Use Roon’s Muse Parametric EQ function to introduce such a correction filter.
When playing with the settings, you are presented with a graph depicting the resulting frequency response - it can’t get much more intuitive than that.
I know Muse Parametric EQ is quite intuitive, nevertheless I did not find a way to achieve what I want [moderated].
Hi @Sylvain74,
Some pointers to help get you started … with DSP it never a case of “one size fits all” so please share specifically which steps you are having difficulties with?
I think the first thing is to determine what approach you wish to take:
A simple manual created parametric filter, based on your listening tests and/or external measurements.
Full Room acoustic analysis, with a 3rd party software to generate a convolution filter that loaded into Roon.
Here’s a couple of guides these:
I will try to use a Low Shelf with attenuation of 5db below 150Hz and another Low Shelf with gain of 5db below 60Hz in order to cancel attenuation below 60Hz.
I tried as well a parametric filter centered at 105Hz with Q=0.67 but it looks less efficient.
Hey @Sylvain74, as others have shared, EQ can be a tricky. What your room measurements show is needed may not sound appealing once it’s dialed in. So, it takes a bit of experimentation to get things right. Try the shelf EQ you’ve proposed and then consider working with a peak/dip filter like the one I set up below.
Best of luck
