Today's Lesson

We will use our parametric EQ to mold and shape the sound of each instrument by cutting or boosting certain frequencies.

While boosting frequencies is easier to hear, it’s a better practice to listening for problematic frequencies and then reduce those first.

If you’re not exactly sure where an offending frequency is, then you can apply the “Boost, Sweep and Cut” method to identify the problem.

Start by placing your frequency center point where you believe the problem is. Using a narrow Q, boost the frequency center point about 6 to 8 dB. Sweep it across the frequency spectrum until you hear the problematic tone and then cut that frequency until the unpleasant tone is gone. You can then choose whether to widen the cue or not. Widening the cue will cut more of the surrounding frequencies, while keeping it narrow will eliminate a smaller range of frequencies.

Use the “Boost, Sweep and Cut” method with care when mixing in a live sound application as microphones can easily feedback in the stage monitors while in the boosting phase.

Once you have identified and cut the unpleasing elements, then you can ask yourself, “What can I boost that will make this instrument stand out even more in the mix?”
