And then, an audio signal in the voice signal section is inputted to the comparator as a second basic frequency signal. The comparator compares the first and second basic frequency signals with each other and calculates a difference value therebetween, and then inputs it to a microprocessor. The microprocessor outputs a signal for scoring the singing of the singer on the basis of the difference value.Field of SearchCATHODE RAY SCREEN DISPLAY AND AUDIO MEANSKaraoke AUDIO RECORDING AND VISUAL MEANS Common carrier for visual means and audio recording Audio recording on disk MEANS FOR DEMONSTRATING APPARATUS, PRODUCT, OR SURFACE CONFIGURATION, OR FOR DISPLAYING EDUCATION MATERIAL OR STUDENT'S WORK Keyboards Tuning devices Indicators Data storage Note sequence Accompaniment Rhythm Selecting circuits Mixing MIDI (musical instrument digital interface) Track centering During vertical blanking Sound signal IMAGE SIGNAL PROCESSING CIRCUITRY SPECIFIC TO TELEVISION Fades signal generator Plural parallel light modulators | |
