Ok, here’s a question. And the trick here is I don’t want a technical answer, I want it in layman’a terms, an idiot proof answer that will make me go ‘aaaah! I see!’ after all these years.
I can just about ‘get’ how a mono record stylus would make sounds – the tiny bumps in the record vibrate the needle and those vibrations are then amplified into sound – check. That does me, I don’t want to hear any more about mono sound.
But how do you get STEREO sound, two completely different sounds, from a single needle on a single groove?
I need a snappy answer here, something I can pass off as my own knowledge if I need to at one of my many dinner parties.
I’ve had people talk to me about a river with two sides, I’ve heard talk of ‘sum vs difference’ and whatnot…. but can someone just EXPLAIN how it works?
Honestly I wish someone had just lied to me and told me there are actually two separate tiny needles, not one. I probably would have died happy and I wouldn’t even have bothered to check.
Can anyone put me out of my misery?
