So this might be a dumb question but I’ve never understood how etching a Grove into some plastic can lead to the same sound as a human singing with backing instrumental? It just never made any sense to me
In: Technology
Sound is simply variations in sound pressure. Take a sheet of paper, and mount it in a frame, so that it’s held securely. If you blow on it, it’s going to flex away from the air.
Now attach a needle to that and make it make a groove in something, which will follow those vibrations in the air.
That’s really all there is to it. All sound, no matter how complex, adds up to some amount of deflection during a point in time. If there’s multiple sounds at once they just add up with each other.
