Inna, the proper word was "analogous", not similar to that used on "Star Trek"; a big difference, but I couldn't spell analogous at the time, and used a word that I thought was "similar". There is a world of difference between the two in my explanation of analog to digital.
In digital,there is no such thing as "left" and "right" channel, so how does all that stuff get back together; not to far from "Star Trek" is it?
Enjoy the music.
