  • Music means a lot to us, By just putting a record on it helps us process emotions, escape

  • reality, or just get really pumped up about something. But how did that sound get on a

  • piece of vinyl in the first place? And how does it make music to our ears.

  • Hey Audiophiles Julia here for DNews

  • I know it seems like a simple thing, but how do we record sounds on to vinyl?. How does

  • this vibration produced in our throats get carried through the air, and capture on disc?

  • Well it wasn’t easy. for centuries there were attempts to transcribe sound on to paper.

  • Back in the mid-19th century, scientists were studying how sound waves move through the

  • air and vibrate. Inspired by studies of the inner ear, French scientist Édouard-Léon

  • Scott de Martinville, tried to recreate the ear drum with a thin membrane. Attaching this

  • membrane to a stylus or etching pen, he could trace the vibrations that hit that membrane

  • onto a piece of paper or glass. But it took at least 20 years for anyone to realize that

  • heythese 2d lines on a paper, if turned into 3d grooves in something, could be played

  • back!

  • The earliest attempts at recording the human voice go back to the 1870s. And like most

  • inventions of that era, was developed at Thomas Edison’s labs. Once we had sound waves figured

  • out, there had to be a way to mark them down somehow and re-play them later. Edison’s

  • labs came up with a cylinder covered in tin foil with a needle attached to a thin membrane

  • called a diaphragm. As sound waves hit the diaphragm they jiggled the needle which etched

  • the vibrations and movements into the cylinder.

  • But he wasn’t the only one working on it. Emile Berliner developed a similar system,

  • but his had hand crank that turned not a cylinder but a flat disc cutting 3-dimensional grooves

  • of sound waves directly into it. The needle or stylus wouldreadthe grooves, producing

  • a sound that was amplified by a horn or cone. And thus the gramophone was invented in 1887.

  • And that’s still how analog sound is played today. Records work on a similar principle,

  • only instead of recording it fresh each time, it's recorded to a master disc and then pressed

  • into vinyl Today’s record players have the stylus, usually made from diamond or sapphire,

  • attached to a tone arm, that’s the thing you pick up and move to put on a record. Tone

  • arms can be straight or curved, and there’s some debate as to which is better. And the

  • sound isn’t amplified mechanically, they are carried through the tone arm to a cartridge

  • containing coils in a magnetic field. These coils take the vibrations and amplify them

  • electronically through speakers.

  • But on a warmer note, many record fans say they sound just that. They believe records

  • sound better and warmer than other forms of recording because of its fidelity. But that’s

  • an arguable case. But maybe the rise of record players lately is simply because many vinyl-philes

  • say they have an emotional connection to records. Some say it’s a nostalgia factor, others

  • like that records are so tangible, theyre something you can really see and feel. Maybe

  • it’s the appeal of the ritual, the taking off of the jacket, placing the record on the

  • table and finally get the stylus, literally in the groove.

  • So while some might get a little down on digital, it can be awesome, I mean modern scientists

  • have even found a way to listen to those Scott de Martinville’s recordings using a virtual

  • stylus. Seriously. it’s creepy. give it a listen, there’s a link in the description.
