Write it into digital memory, and then play it out backwards.Ok, Nigel, this is why your are so damn smart....that example explained it perfectly. ok, so lets say that I have a stored fragment, about a minute long, how would I go about reversing it. I really dont want to use tape, and a mechanical recorder, which Im certain is going to come up soon, from someone.
there was a weird TV series in the late 1980s/early 1990s called "Twin Peaks", which often had dream sequences which were filmed, and the script was all backwards. then when it was edited into the show the whole sequence was played backwards, and all the dialogue was forwards english, but with a weird backwards feel to it because all the consonants in the words had the consonant sounds backwards....An example would be "hello its Kim" to "mik sti olleh"
