68 Chapter 10 Mixing and Adding Effects
Types of Effects
GarageBand includes the following types of effects:
Equalization (EQ): EQ is a powerful and versatile effect that lets you change the level of
selected frequencies. You can use EQ to make both subtle and dramatic changes to
your songs. EQ is likely the most commonly used effect in popular music.
Dynamics: Dynamics effects, which include compressors and noise gates, let you
control the volume of your music over time.
Reverb and Echo: Reverb and echo are both time-based effects. Time-based effects store
a copy of the sound and play it back at a later point in time, creating a sense of space.
Modulation: Modulation effects, which include chorus, flangers, and phasers, build on
the time-based effects by shifting or modulating when the copied signal plays back.
They can also involve detuning the copied signal relative to the original.
Distortion: Distortion effects, which include amp simulation and overdrive (and, of
course, distortion!), change the tone of the original sound to recreate analog or digital
distortion.
Other effects: Other effects included with GarageBand, such as tremolo and Auto Filter,
change the sound in different ways.
Adding Effects
Each Real and Software Instrument track has a set of effects, which include a
compressor, equalizer (EQ), echo, and reverb. You can adjust a track's effects, and add
up to two additional effects, in the Track Info window. Real Instrument tracks also
include a noise gate effect.
The master track includes its own effects, and you can adjust the master effects and
add one additional effect to the master track in the Master Track Info window.
To add an effect:
1 Click the Track Info button (the letter “i”) or choose Track > Show Track Info to show the
Track Info window.
2 If needed, click the Details triangle to show the Effects section of the window.
