I have a recording of a old band of mine from 20 years ago. It is on 2 unmarked VHS looking ADAT tapes. I have no idea if it was recorded in 16, 18 or 20 bit. I am willing to buy a used machine to extract the tracks... but, I need an idea of what to get. Will a 16 or 18 bit recording play on a 20 bit machine? Any help is appreciated?
