A mechanical sound recording is based on cutting (or extruding) grooves in the material of a recording medium using a sound recording device — a recorder. When playing along the groove, the needle of the reproducing device – the pickup – moves (moves).
In the process of developing mechanical recording, two main methods of modulating the groove were proposed: transverse, in which the cutter oscillates left and right from the neutral position and the groove of constant width acquires twists (Fig. 1a), and the deep, in which the cutter moves up and down from neutral position by cutting a groove of variable depth and width (Fig. 1, b).

All preliminary operations for recording and editing phonograms are carried out using magnetic recording. The finally mounted magnetic phonogram is transferred to a mechanical one on a mechanical recording machine (Fig. 2). It has a Continue reading
Rock and roll literally excited the youth of America in the mid-50s of the last century. And then the whole world. And while boys and girls sang along with popular singers and lit on the dance floors, their parents opposed the “innovations” in the music world. Why has this style gained immense popularity and why has it become an apple of discord between generations? About this and not only our page.

The name “rock and roll” came from the popular song “We’ll rock, we’ll roll”. This happened in 1952. Continue reading
The first thing that you should understand for yourself is how, in case of any disease, treatment started on time after a cold will lead to recovery much faster. Therefore, as soon as you feel the first symptoms, we advise you to immediately take a set of measures aimed at treating the vocal cords.
The second – it is necessary to exclude the loss of voice due to reasons not related to the disease of the ligaments, for example, pathology of the nervous system, accompanied by a violation of the innervation of the larynx and throat. Usually these are serious reasons requiring a serious medical approach, and often surgery. Continue reading
