An audio signal is a representation of sound , typically using either a changing level of electrical voltage for analog signals , or a series of binary numbers for digital signals . Audio signals have frequencies in the audio frequency range of roughly 20 to 20,000 Hz, which corresponds to the lower and upper limits of human hearing . Audio signals may be synthesized directly, or may originate at a transducer such as a microphone , musical instrument pickup , phonograph cartridge , or tape head . Loudspeakers or headphones convert an electrical audio signal back into sound.

522-551: Is the path an audio signal will take from source to the speaker or recording device. Signal flow may be short and simple as in a home audio system or long and convoluted in a recording studio and larger sound reinforcement system as the signal may pass through many sections of a large mixing console, external audio equipment , and even different rooms. Audio signals may be characterized by parameters such as their bandwidth , nominal level , power level in decibels (dB), and voltage level. The relationship between power and voltage
