A vinyl killer is a device used in recording studios that takes a recording from a vinyl record and turns it into a digital audio file. This allows the music from the record to be shared and used on digital devices like computers, smartphones, and mp3 players. The vinyl killer reads the record, like a needle reads the grooves of a vinyl record, and then it converts the sound into a digital file using a built in computer. The digital file can then be shared and used on different devices.
