Getting started and functioning

1) Overview

1.1) Opportunity for vinyl recorders

Currently, vinyl disc industry facing to a shortage of polymers. This is due to the fire at the Apollo Masters factory and the covid-19 sanitary crisis. Order delays are very long and the prices have increased about 30% to 40% for industrial vinyl pressing. This leads to an almost impossible access to the small customer because the biggest customers are delivered before. It is therefore the small groups of music which have difficulty in making their own small series of vinyls. Vinyl recorders can solve this problem and make album creation accessible to small music bands (20 or 50 copies).

1.2) What vinyGo offers

Refresh old-fashioned vinyl technology by creating your own vinyls for:

1.3) How a vinyl recorder works

Burn sound on a matrix (vinyl) 

It is the engraving of the audio signal by microgrooves on a matrix. Sound recording is in real time. A diamond, connected to two speakers (for stereo), vibrates above the blank lacquer which turns at 33 or 45 turns. The vibration is made by the speaker when the audio signal is played. This means that a groove is the exact representation of the speaker membrane vibration.

Mastering & Cutting

Before cutting the vinyl you have to apply some equalization like an iRIAA to the audio file. For the “cutting” you need to use a specific engraving diamond with an angle of 90 °.

1.4) Video

Note: The video sound is the sound of vinyl!

Sound extract "eye of the tiger" less than 20sec to respect copyright, and show the sound quality:
