Now play the project from a point before the fade-out begins. You’ll hear all the tracks
in the project fade out gradually to their final volume level.
To manually add a fade-in or fade-out:
1 Choose Track > Show Master Track.
2 Choose Master Volume from the menu in the master track header.
3 Add control points to the beginning of the volume automation curve for a fade-in, or
to the end of the curve for a fade-out.
4 Move the control points to adjust the length and intensity of the fade-in or fade-out.
Using Effects in GarageBand
Effects let you shape and enhance the sound of your music in a variety of ways. Anyone
who has listened to much popular music, or listened to movie soundtracks, has heard
the different effects used in contemporary music. GarageBand includes a complete set
of studio-quality effects that you can use on individual tracks or the overall project to
shape the sound of your music.
Types of Effects
GarageBand includes the following types of effects:
Compressor: A compressor adjusts the volume of the music to smooth out sudden
level changes. Compression can add punch and definition to a track or an entire song,
and make it sound better when played on audio equipment with a narrow dynamic
range.
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.
Echo: As the name suggests, an echo effect repeats a sound like an echo. It can add a
subtle sense of space to a sound, or create the impression that a voice or instrument is
in a large room, a cavern, or outer space.
EQ: EQ (short for equalization) 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 projects. EQ is likely the most commonly used effect in popular music.
GarageBand includes a special type of EQ called Visual EQ. You can use Visual EQ by
choosing an EQ preset, but you can also edit the effect graphically, making it easy to
see what part of the sound you are changing.
Gate (Noise Gate): A gate reduces low-level noise by cutting off the sound when it
falls below a certain volume level. It is often used as the first in a series of effects, and is
included on Real Instrument tracks to help reduce input noise.
