Digital recording and reproduction uses the same analog technologies, with the added digitization of the sonographic data and signal, allowing it to be stored and transmitted on a wider variety of media. The digital binary numeric data is a representation of the periodic vector points in the raw analog data at a sample rate most often too frequent for the human ear to distinguish differences in quality. Digital recordings are not necessarily at a higher sample rate, but are often considered higher quality because of less interference from dust or electromagnetic.
