Equalization in mastering
When mastering, you will use a parametric equalizer. We learned how to use a parametric equalizer in Chapter 6, Compression, Sidechaining, Limiting, and Equalization, so refer to that chapter if you need a refresher. Parametric equalizers show audio levels at each frequency and have band filters to apply EQ to selected frequencies. A band filter is a tool used to isolate certain frequency ranges and reject frequencies outside its range. You can then perform effects on selected frequencies in the band filter. The following is an example of a parametric equalizer:

Parametric equalizers break up audio frequencies into multiple filter bands. You can then either increase or decrease the level of a band. By increasing, you'll boost a sound. By cutting, you'll reduce selected frequencies. Boosting frequencies of a sound brings the sound more in to focus. Cutting frequencies is useful for...
