I was wondering how to make the EQ settings more absolute rather than just listen to a sample of audio and choose the presets which don’t always match up. There are so many variables with what we hear. I have many custom EQ settings that are subjectively nicer. You might as well.
This was how I tested it.
I noticed there are 100 bins of sound vs. the max = 31 slider bins. But there are 100 vertical bands above this in the display and shifted to the left so they do not line up with the 31 sliders. Boosting 1 band proves that. We often need to suppress room and speaker resonances in a narrow band which was my motivation as well as brighten weak tweeters then the EQ presets might match my expectations.
I “generated” some -3dB/octave “pink noise” in Audacity and checked out my FXSound settings.
Background
White noise is flat per Hz, so on a log frequency axis it rises +3 dB per octave. Thus Pink noise is -3 dB and should be flat with the 31 band settings,
Using Q=max = 3 means in settings means BW.=“1/3 octave” whereas an instrumental Spectrum Analyzer selects a fixed filter BW.
I suppose the 100 band EQ display in 3 decades or ~ 10 octaves is a 10% octave display so the amplitude of each bar does not match the power in each filter channel. Perhaps that is compensated for equal amplitude. IDK.
I am attempting to start with a flat display signal then tuned what I hear from that to make the visual feedback more accurate.
