How Does a Needle Read a Record
Have you e'er wondered how something as complicated as a vocal can be perfectly recorded onto the surface of a flat, round disk of vinyl, that can be reproduced on mass for anyone to ain, play and listen to whenever they choose?
The history of recording and reproducing audio
Having access to music whenever and wherever you want is something many of us have for granted but have y'all ever imagined what it was like before this was possible? Earlier we had discovered a way to record and playback sound the only way to hear music was to have someone play it, or play it oneself. Imagine what a massive conceptual shift recorded music would had been for people once they were able to hear music, at volition, without someone performing it in their presence for the first time. To fully understand the genius behind vinyl you first need to know the origins and history of recording and reproducing sound.
The history of recording and reproducing audio is a menses spanning over a century. In 1877 Thomas Edison invented a device that could tape and reproduce sound for the start time, not on a disc only a metal cylinder. The term 'gramophone' was coined by Emile Berliner whose system played lateral-cut disc records the were first marketed in Europe in 1889. The golden historic period for vinyl records as we know them was from the inception of the vinyl LP in 1948 to 1988 when CDs out sold vinyl for the first time, only vinyl had its first taste of contest from the Phillip's Cassette, when it was released in 1962.
After decades of music seemingly disappearing into a calculator hard bulldoze, january 2017 saw Vinyl sales topping three million, the highest Great britain full in 25 years. More than than 3.2 million records were sold in 2016, a ascent of 53% on the previous yr. If you are someone who considers themselves passionate near music, vinyl remains the singular most impressive format of recording and reproducing music. So it's only right we honour the vinyl record past fully understanding the genius behind information technology.
Sound waves
To sympathise the genius behind vinyl you starting time need to sympathize how audio waves work. Sounds are produced past vibrations and travel through the air every bit waves, which are vibrating particles. The waves transfer free energy from the source of the sound out to its surroundings. Your ear detects sound waves when vibrating air particles cause your eardrum to vibrate. The bigger the vibrations the louder the sound. The groove you can see on a vinyl record is like a fingerprint of the sound waves captured in a lacquer disc that we call a vinyl tape. These three-dimensional cuts within the spiral groove on the vinyl record are a recording of how the sound waves deport as they motility through the air.
The stylus and the grooves
A typical record histrion has a type of needle called a stylus that is placed gently on the vinyl tape resting in the showtime of the spiral groove. As the vinyl disc steadily rotates the stylus moves through the wavy three dimensions that are cut into the spiral groove. The stylus is a tiny crystal of sapphire or diamond mounted at the very end of a lightweight metal bar similar a needle. Every bit the crystal vibrates in the groove, its microscopic bounces are transmitted down the bar. The stylus fits onto the cease of an electromagnetic device chosen a cartridge, containing a piezoelectric crystal. The metal bar presses against the crystal and each time it moves, it wobbles the crystal slightly, generating an electrical betoken. These signals are fed out to the amplifier to make the sounds yous hear through your speakers or headphones. Not all record-histrion cartridges employ piezoelectricity to convert sound vibrations to electric signals. Some have tiny electrical coils and a magnet inside them. When the stylus moves, information technology pushes the magnet upwards and down past the coil, generating electrical signals that are fed to the amplifier to create sound through your speakers.
Many record collectors and DJs say the sound of vinyl is far superior and much "warmer" than digital music and this is why vinyl has always been the showtime choice for any music connoisseur. However, this is factually incorrect. The Whittaker Nyquist Kotelkinov Shannon Sampling Theorem describes how audio waves can exist replicated perfectly using a sampling rate twice that of the frequency limit when using a ring-limited signal.
The revival of vinyl is testament to its appeal and nostalgia. There is something undeniably enjoyable about collecting, playing and mixing with vinyl. If you would like to learn how to beatmatch and mix with vinyl records click hither to contact us.
