Computer real-time analysis system for singing and playing

Abstract

The invention relates to a computer real-time analysis system for singing and playing, comprising a segmental package-inspection device of an acoustical signal, a real-time recording, storing, displaying and playing device of acoustical signal time-domain data, a device for drawing time-frequency-intensity joint picture with fast Fourier transform for a short time, a device for drawing time-frequency real-time spectrum with fast Fourier transform for a short time, a device for recognizing fundamental tone, harmonic tone and resonance peak of sound, analysis processing and displaying, a devicefor rhythm recognition of the sound, analysis processing and displaying, a device for analyzing and sorting-out into an opern and displaying according to the information such as fundamental tone, libretto, rhythm and tuning systems; and a device for modifying, recording, storing, evaluating, displaying, playing and transmitting an acoustical time-domain and frequency-domain signal. The system carries out computer real-time visualization and systematical and quantitative measurement and test to vocal music and instrumental music, and sing state and playing state can be recognized and guided byadopting the computer image and video automatic recognition technology.

Description

technical field [0001] The invention relates to a computer real-time analysis system for singing and playing. technical background [0002] For a long time, due to the limitations of the level of science and technology, and due to the inherent complexity of vocal music (singing) and instrumental music (playing) (involving musicology, mathematics, physics, physiological anatomy, psychology and other disciplines) and subjectivity ( It is difficult to observe the internal cavity of human activities, individuals have different self-judgments on aesthetics, the audience is limited by the physiological threshold of the human ear, and cannot accurately hear the entire range of the singer's actual singing voice, etc.), people's research on vocal music and instrumental music It has been only qualitative or slightly quantitative, and has been very lacking in real-time visualization, systematic and quantitative measurement and testing of vocal and instrumental music, especially in the ...

Problems solved by technology

[0005] 1. When singing, the singer himself cannot hear the real situation of his own voice. The main reason is that the vibration of each vocal organ of the singer affects his auditory nerve, causing the singer to have false hearing; The sound wave of the sound propagates forward (especially the higher frequency sound), rather than to the singer's ears on both sides, so the singer cannot hear the true authenticity of the sound when singing, so that the singing In addition, subjective conditions such as the auditory memory of the previous singing by oneself and others, fatigue or numbness caused by repeated singing also affect the true response of the singer's hearing during singing;

[0006] 2. When playing, the performer himself cannot hear the real si
