   right, I never thought of that. likewise dolby was also an analogue mode   
   of compression, I still have a working tape deck!that can do dolby b and   
   c. short before analogue tape became obsolete there was also dolby s.   
   the best tape decks were the 3 headed ones, where you could listen to   
   your recording on the fly, while it was recorded! they could fit a   
   record/play head on one piece, mine is a regular auto reverse, twin   
   deck. one of the  last good quality to be made.
