Array display audio signal circuit

Audio signal is (Audio) the information carrier of regular sound wave frequency and amplitude changes with voice, music and sound effects. According to the characteristics of sound waves, audio information can be classified into regular audio and irregular sounds. Regular audio can be divided into speech, music and sound effects. Regular audio is a continuously changing analog signal that can be represented by a continuous curve, called a sound wave. The three elements of sound are pitch, intensity and timbre. Sound waves or sine waves have three important parameters: frequency ω0, amplitude A n and phase ψn, which determine the characteristics of the audio signal.
