Use effect plug-ins in GarageBand for iPhone
Effect plug-ins are used to shape and enhance the sound of your music in a variety of ways. Many familiar sounds in popular music are created using effects. Effects include reverb, compressors and delays. You can use multiple plug-ins on each individual track and change the order in which they affect the sound.
Effect types
GarageBand includes a variety of effect plug-ins that you can use on the tracks in your songs:
Bitcrusher: A bitcrusher creates distortion by reducing the sampling rate and bit depth of the signal. The result is a lo-fi digital sound similar to old video games or drum machines.
Compressor: A compressor adjusts the volume of the sound to smooth out sudden level changes. Compressors can add punch and definition to a track, making it stand out from the rest of the mix.
Delay: Delay 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 an instrument is in a large room or cavern.
Distortion: Distortion and overdrive effects change the tone of the original sound, making it sound “dirty” or “fuzzy”.
EQ: EQ (short for equalisation) lets you change the level of selected frequencies in a sound. You can use EQ to make both subtle and dramatic changes to your songs.
Modulation: Modulation effects, such as chorus, flanger and phaser, repeat the sound along with the original, but they shift or modulate the repeated sound during playback. The result is often a shimmery or swirly effect on voices and instruments.
Reverb: Reverb simulates the natural reflections of a sound in a surrounding space. It can add definition and presence to voices and instruments, add ambience to a sound, or simulate different rooms and other acoustic environments.
Tremolo: Tremolo raises and lowers the volume of a sound at regular intervals, creating a wobble effect.
Vocal Transformer: The Vocal Transformer changes the pitch and tone of your voice.
