Compressors and Limiters

Compressors and limiters are audio signal processing devices that help maintain a high average volume by controlling the dynamic range. Basically they keep the sound from getting either too quiet or too do this by automatically tuning down the loudest sounds when they exceed a certain volume threshold. The amount of attenuation, called “gain reduction” or GR, depends upon the position of the volume threshold and also a setting called the ratio or slope.
