CNS is a ‘one shot’ noise reduction system, similar to Dolby but it works on playback only signals to reduce background noise.

I developed it specifically for the Trackplan system and it was a competitor to dBX. It works by splitting the audio into 4 bands and expanding them independently, then re-combining them. Nowadays it is not particularly relevant because noise is no longer a problem, but it might be useful as an expansion effect. :)
