Physics of the Turntable

Have you thought about the structure of gramophone? It may not be the case. After all, who still listens to the record. To my surprise, the turntable is coming back. Due to the growing interest in recent hip - hop music, attention is gaining attention on the turntables the DJ is using to provide beats, loops and scratches to almost all hip - hop groups of today. The internal movement of the turntable may seem complicated at first at the beginning, but after reading this article, it is clear that record producers will behave according to the basic principles of physics just like everything There should be.

Since I first saw good DJ play, I have been fascinated by the physical nature of the turntable. Like mostly lonely people, I have manipulated the turntable independently from any scene or environment. When I created my own complicated skills for my decades to early twenties, especially for deck culture (especially now there are a lot of DJs). Then I began to introduce these pioneers of all these wonderful electronic music like Daphne Oram and Eliane Radigue which played such important roles in the development of electronic music, and I began to feel pedigree It was. Regarding pedigree in particular, when I played the world premiere of Still Point, I felt that Daphne Oram was very close to the work Daphne Oram made for the orchestra and turntable in 1949. When I sang the part of the turntable in 2016, I felt real blood, for example in a concert, I will also see another big role model for me, late Porin Oliveros.

I use my own motion-based turntable technology for sound processing and real-time sampling. Therefore, I pay close attention to the physical nature of the sound, and the way the rotating turntable's speed and motion directly manipulate the sound. When I evaluate acoustic works (orchestra etc), I also use manuscripts and pencils. In the photo of my studio (bottom), you can see the device on the turntable on the left rear platform. This is a motion and object-sensitive sculpture by Haroon Mirza, an artist who changes the wheel to gain power from the deck's arms. I also have a zoom recorder, I use a turntable to do my live mix, and usually record sounds on my deck.

ELPJ, based in Japan, sells laser turntables that read vinyl disks without using physical contact with laser optics. Using a laser turntable eliminates the possibility of recording wear and accidental scratches and reduces the sound, but its cost limitation is mainly used for analog archiving of digital archives. Various other laser-based turntables were tried in the 1990's, but if the laser reads the groove very accurately, the dust resulting from the electrostatic charge of the ethylene gene will not be mechanically pushed out of the groove, It does not touch and it deteriorates. Sound quality freely usable compared with conventional stylus playback
