Compressor - Arturia ACID V User Manual

6.5.7. Compressor

A Compressor is used to control the dynamic range of a sound: it reduces the difference
between the softest and loudest levels a sound can have. It does this based on reducing a
gain by a certain amount (the ratio) once the audio releases a certain level (the threshold).
Control Description
Makeup Enables control of the output level to compensate for the gain reduction of the input
Threshold (H) Sets the level where compression will begin
Ratio (V) Determines the amount of compression to be applied once the threshold is reached
Output Gain
Attack
Release Sets the release curve of the compressor

♪ There's an old audio joke that's great for understanding compressors. Threshold is how loud your
music has to be before your parents tell you turn it down. Ratio is how much you turn it down. Attack
is how fast your parents react once it's too loud. Release is how soon you turn it back up once they're
gone.
