Learning EQ Ranges

Learning EQ Ranges
0.0 0


I recently read this article “The Significance of 632Hz” here:

I was particularly struck by the simplicity of how the EQ frequencies were broken down and an even easier way to remember them. Ever wonder which frequencies someone means when they say “upper-mids” or where the frequency ranges start/end? (Hint: just remember 20 and 63.)

Ranges from the article:
20: Sub
63: Bass
200: Low mids
630: Mids
2000: Upper mids
6300: Treble
20000: Air

After reading the article, now all I have to remember is 20 and 63. And speaking for myself, THEN go do the reps and learn what they actually sound like. Cheers!


The soundcloud sound bite covering the divisions is a great “visual”.


Very interesting and good to know!


Interesting. That’s an angle that I’ve never really considered. Makes sense that it would make it easier to listen for it that way.


Nice article.
I have seen a few broad eqs modeled that way but some modern approaches are translating it into octave bands and third octaves bands instead (Bonello)
In acoustics and human hearing, octave bands play a bigger role than the broadband divisions we are familiar with. As in, you would be approaching mixing from an octave perspective instead.
Here is some more info on the octave bands
