Thanks Richard, for speaking up with accuracy. I have given up trying to educate clients on this. Usually they want mp3s from CD, and don’t realize they could do that themslves with iTunes! But I don’t disabuse them of the notion if they want to pay me to do it. I can usually make them sound better anyway… :-) <L> Lou Judson Intuitive Audio 415-883-2689 On Oct 11, 2018, at 12:08 PM, Richard L.

"Ripping" is the proper word to use here (as was used in the discussion).
