Chapter 9 Working With Audio Effects 201

Graphic EQs

Graphic EQs give you a set of filters (often with 10 or 31 filters), each with a set center

frequency and bandwidth. Using a graphic EQ, you can shape a wide variety of

frequencies throughout the frequency range. Graphic EQs can be used to shape the

sound of the overall project mix.

Parametric EQs

Parametric EQs are similar to bandpass EQs, but provide a greater amount of control,

and can be used for extremely precise adjustments. With a parametric EQ, you can set

the center frequency, the gain, and the bandwidth. Used carefully, a parametric EQ can

help a track cut through the mix, or help a track or project sound fuller. Parametric EQs

can also be used to remove specific, unwanted frequencies from a mix.

Modulation Effects

Modulation effects begin with a delayed signal, like time-based effects, but vary (or

modulate) the delay time, typically using an LFO. This can be used to double a sound,

making it seem stronger and “fatter,” to simulate a group of voices or instruments

playing together, or to add a distinctive character to the sound. Modulation effects

include chorus, phase shifters, and flangers.

Chorus

Chorus effects play back multiple repetitions of the delayed signal (like reverbs), but

vary the delay time for each one, using an LFO. As the name implies, this effect can

strengthen the sound, and create the impression that the sound is being played by

many instruments or voices in unison. The slight variations in delay time created by the

LFO simulate the subtle differences in timing and pitch heard when several people play

together. Using chorus also adds fullness or richness to the signal, and can add

movement to low or sustained sounds.
