In this video, we put a Quadraphonic Vinyl Record (Both SQ and CD-4) under a scanning electron microscope (SEM)
You’ll see:
• How it all works?
• SQ and CD-4 quadraphonic formats.
• Ultrasonic pattern
• Physics behind all these things.
I love putting "everyday" objects into an electron microscope — and Quadraphonic vinyl records reveal one of the most beautiful micro-worlds I’ve ever seen. Is analog sound really magic? Or just physics?
Let’s take a look inside the groove.
