"Analog means that there is a continuous signal in which the varying part of the signal is a representation of another time-varying quantity. So, when it comes to sound recordings, the instantaneous voltage of the signal varies continuously with the pressure of the sound waves. Basically, the groove of a vinyl record is like a drawing of the sound wave in a single continuous line through the entire side. Your turntable essentially reads that and decodes it in real time, which results in the sound you hear from the speakers."
That's why using Vinylcat Record Cleaner is happy to help you restore your "grooves" to like-new! Thanks for your support.
