Amplifiers

Amplifiers boost the signal of an audio signal to make it louder.

Compressors

Compression reduces the dynamic range of audio by reducing the level of the loudest parts.

Delay

Delay repeats audio at a decreasing volume each time, creating an echo effect.

Distortion

Distortion is used to alter the sound of instruments, usually by increasing their gain, producing a "fuzzy", "growling", or "gritty" tone.

Filters

Filters are used to boost or diminish certain frequency ranges.

Gates

Gates control the dynamic range of audio by removing anything below or above a certain threshold.

Limiters

Limiters are used to decrease the loudest parts of audio without affecting everything else.

Metering

Meters are used to measure different aspects of an audio signal.

MIDI

These are plugins or programs that output information to a MIDI channel.

Modulation

Modulation plugins control certain parameters over time based on controls within the plugin.

Reverb

Reverb simulates placing a sound in a reverberant, or echoey space.
