A lot of people think that the Dolby Noise Reduction button on their cassette deck should be switched off for playback. Why? Because the sound is dull with it switched in. So did it ever work? Why didn't people like it? ❤️ Support My Channel ❤️ https://www.buymeacoffee.com/davidmellor

ERRATUM
I gave the width of cassette tape as an eighth of an inch, which is probably too much of an approximation. It should be 0.15 inches. Wikipedia states "The tape in a compact audio cassette is nominally ⅛ inch but actually slightly wider (3.81 millimetres (0.150 in))" DM
