Those of us who grew up with audio cassettes remember the Dolby noise-reduction system for reducing tape hiss. It made cassettes capable of "high fidelity" music reproduction, at least by the standards of the 1960s-70s (pre-CD era).

I didn't know that he had a Ph.D. in physics from Cambridge (England)!
