DEVICE FOR ANALYZING AND VISUALIZING MUSIC IN REAL TIME

PURPOSE: A device for analyzing and visualizing a music in real time is provided to visually display a music as various patterns in real time. CONSTITUTION: An input unit(10) receives an audio signal and converts the signal into digital data capable of being processed in a signal processing unit(20). When the audio signal is outputted as an analogue signal in an audio reproducing device, the input unit(10) includes an A/D converter for converting an analogue output signal from the audio reproducing device into digital data. If the audio signal is a sound wave signal as a person' voice, the sound wave signal is converted into an analogue electric signal using a microphone, and the signal is amplified as a level capable of being used in the A/D converter using an amplifier. The amplified signal is converted into a digital signal in the A/D converter and outputted to the signal processing unit(20). If the audio signal is outputted in a digital audio reproducing device, the digital audio reproducing device is directly connected to the signal processing unit(20) without an additional A/D converter. As the input unit(10), a sound card of a general PC may be used. The signal processing unit(20) extracts a characteristic of the audio signal from the digital audio data of the input unit(10), and controls an output unit(30) for generating visual effects based on the characteristic.
