- [Voiceover] Equalization, or EQ for short, alters the relative amplitude of different frequency ranges. Here, we'll make use of a parametric equalizer which gives us a lot of control over the sound with several different EQ tools, including high pass and low pass filters, high shelves and low shelves, and peak notch filters. Digital parametric EQs are great because they visually show how the amplitude of certain frequencies are being adjusted within a sound. When it's flat across the zero decibel mark, it means all frequencies pass through at their original volume. Wherever the curve goes up or down from zero, it means partials in the sound at those frequencies are turned up or down that much in amplitude. Most of the tools in the EQ toolbox create specific shapes in the curve. Let's look at the most common ones. First, we have the low pass and high pass filters. The low pass let's low frequencies pass through and progressively cuts the highs, which is useful to deliberately muffle…
