The “Track EQ” added automatically on every audio track is sort of like this. 1 = Bass, 2 = Low Mid, 3 = High Mid , 4 = Treble.
The good thing about it, though, it that it’s more versatile in that you can change the frequency each sits on and you can also change the “width” each one covers – so it can cover a very narrow or very wide frequency range.
This is like the EQ built into our professional sound board. Four frequencies (Low, Low Mid, High Mid, High), can change the frequencies (frequency), and can specify how narrow or wide each one affects (Q).
