Some compressors also have the ability to do the ''opposite'' of compression, namely ''expansion''. Expansion ''increases'' the dynamic range of the audio signal.<ref>{{Cite web |url=https://ccrma.stanford.edu/courses/192b/192b_Lecture_1_18.pdf |title=Dynamic Range Processing and Digital Effects |last=Kadis |first=Jay }}{{Cite web |url=https://ccrma.stanford.edu/courses/192b/192b_Lecture_1_18.pdf |title=Dynamic Range Processing and Digital Effects |last=Kadis |first=Jay }}</ref> Like compression, expansion comes in two types, downward and upward.

''Downward'' expansion make the quiet sounds below the threshold even quieter. A [[noise gate]] can be thought of as an extreme form of downward expansion as the noise gate make the quiet sounds (for instance: noise) totallyquieter or even silent, depending on the floor setting.<ref name="Reese" />

''Upward'' expansion make the louder sounds above the threshold even louder.
