Abstract
A method for compressing music into a digital format. An audio signal that corresponds to music is received and converted from an analog signal to a digital signal. The audio signal is analyzed, and a tone is identified. The musical note and instrument that correspond to the tone are determined, and data elements that represent the musical note and instrument are then stored.
