1.3 - Parametric EQ vs Filters for Beginners

I’m experimenting with the EQ settings and at the same time, trying to understand what they are and how they work.

Peak/Dip is self-explanatory enough, where I adjust loudness for a particular frequency, and it’s reflected in the graph.

But how do others, like Low Pass, work? In the graph, the individual frequencies still reflect the loudness levels I set, but the overall curve dips, with one end falling below my settings.

Is the overall curve what I should be looking at? Any help for this EQ noob would be greatly appreciated. :slight_smile:

The overall (white) curve is the result of all your individual EQs and is effectively The EQ applied to the input signal.

So you can experiment with the EQ types individually and see what they do, then combine them however you see fit to achieve your desired EQ overall.

Combinations of Peak/dip will often get you where you need to go.

Low-pass is kind of self explanatory. It’s let’s through the input signal frequencies that are lower than the threshold frequency set, with a slope defined by the Q. Anything above is attenuated. There are tips on what they do if you click on the name (just be careful to not accidentally change from the one you wanted).

Some of them (like high and low pass) are probably more appropriate for digital crossovers etc.

It’s a bit sparse right now, but see the KB too. https://kb.roonlabs.com/DSP_Engine:_Parametric_Equalizer

Thanks Steve. You’re right, experimenting is the best way for me to see what works. I clearly still got lots to learn about the specifics, like what is digital crossovers, etc. Until then, I’ll have some fun skimming around the surface.
