Adjustment of human voice color

Adjustment of human voice color
"No matter the voice of people, songs or instruments, they are not a single sound, but a compound sound
The pitch of a sound and a series of overtones. These overtones are the digits of the pitch frequency, which are called partials in physics and partials in electroacoustics
Harmonics are called overtones in music. It has a very important influence on the characteristics of timbre. The number and amplitude of these overtones are different
The same as the frequency characteristic curve of voice. This curve reflects the expressive force of timbre. For example, the lowest frequency of a piano is
27.5Hz, the highest audio rate is 4186Hz, while the piano has more than ten overtones, and its high frequency can reach 10kHx~20kHz, generally
16 overtones or 24 overtones can be measured. These overtones can be divided into low-frequency overtones, intermediate frequency overtones and high-frequency overtones,. If low
If the amplitude of overtones is strong, the timbre will be thick; If the amplitude of IF overtones is relatively strong, the timbre will be mellow, natural
harmonious; The amplitude of high-frequency overtones is relatively strong, and the timbre is bright, clear, and analytical.
The spectrum curve is to connect the vertices of the pan dawn amplitude of the timbre on the coordinates. This packet route is the pre dawn
Color spectrum curve.
The frequency spectrum curve of a voice is different from that of the material structure, state, intensity of sound production and resonant body
Same but different.
