CX is a noise reduction system for recorded analog audio. It was developed by CBS Laboratories (a division of CBS) in the late 1970s as a low-cost competitor to other noise reduction (NR) systems such as dbx disc and High-Com II, and was officially introduced in 1981.[1][2][3][4] The name CX was derived from "Compatible eXpansion", a feature of the technique.[4]
