Chapter 11. Mixing Audio > Using a Shelving Filter

Using a Shelving Filter

Shelving filters boost or cut all sounds above or below a frequency you set. They are great for gently adding or subtracting bass or treble from a track that doesn't sound quite the way you want it to. For example, a shelving filter would be a good choice for removing unwanted low-end sound from an acoustic guitar, boosting high-end sound in cymbals or percussion, or adding low-end sound to a singer with a slightly thin voice. This task shows you how to cut out unnecessary low-end sound from a track with low-shelf EQ.

To boost or cut with a shelving filter

Click the e (Edit) button in the channel that you want to adjust to open its Channel Settings window.

Only EQ bands 1 and 4 can act as shelving filters; the two middle EQ bands are parametric (peak) filters only.

Turn on the bottom EQ band by clicking its power button (Figure 11.26).

Figure 11.26. The first EQ band is now turned on.

Turn the bottom knob (the Q setting) all the way to the left (counterclockwise).

The display below the knob says “Low S,” which stands for low shelf and refers to the type of filter.

In the EQ display above the knobs, click the breakpoint for the first EQ band and drag it to set the EQ.

The display will show you what the filter is doing, and your ears will guide you to the right settings. In Figure 11.27, the shelving filter is set for a significant cut, with its center frequency set at 341 Hz.
