An audio signal is a representation of sound typically as an electrical voltage. Audio signals have frequencies in the audio frequency range of roughly 20 to 20000 Hz (the 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 … Read more
