Please educate me, what is "pumping"?
Let us give an example. You send music to a compressor. You set it so it will lower the gain of the music (compress) by 10db.. Music plays and gain is reduced by 10db. When there is some silence the gain goes back up by 10db This going up and down of the gain is called pumping. If there is light noise in the background when the music stops the noise will come up 10db. That is pumping. You can here it on remote radio newscasts. When the newscaster stops speaking the background noise comes up
