Ray Dolby, has died. All of the obituaries will mention his staggeringly important contributions to audio engineering. I will point out one more. While still a student, Ray worked at Ampex where he was one of the co-inventors of the first practical color video tape recorder. He not only affected what you hear (and don’t hear), but how you see it as well.
A moment of silence, please.
A moment of silence in Dolby Surround Sound 😉
No hissing.
