I have quite a few old cassette tapes that I'm transferring to CDs. But some of the tapes are not labeled as to whether they were recorded with Dolby B encoding or not. I know some were and some weren't, I just don't know which is which. I try to detect it by ear (switching the Dolby decoder on & off on the cassette deck where I'm playing the tape), but sometimes it's really hard to be sure, especially with just a short listen. Is there a more objective way to detect quickly whether the tape was recorded with Dolby B? Maybe some sort of spectrum analysis?
