A lot of people use “EQ carving.” The other concept you are talking about, I’m going to guess, is “Air EQ,” or EQing outside the range of human hearing (but which effects adjacent frequencies that we can hear). But of course I will have to watch to find out. Thank You for posting the link!!!Here it is. When he demonstrates the amount of low frequency content he takes out, and where and why, that’s one thing I didn’t do as much as he does until after seeing the video.
Also when he narrowly notches up at a corner of a high pass filter or deep subtractive cut, it brings out the emphasis of an instrument when done with awareness and care. Use your ears!
