If the amplitude of low frequency overtone is strong, the timbre is mixed thick

If the amplitude of low frequency overtone is strong, the timbre is mixed thick; If the amplitude of overtone is strong, the timbre is mellow, natural and harmonious; The amplitude of high frequency overtone is stronger, timbre behaves bright, clear, analytical force is strong. The spectrum curve is to connect the vertices of the various early morning amplitudes of the timbre in coordinates, and this packet path is the spectrum curve of the early morning color. The spectral curve of a tone is different, which is different from the material structure, state and intensity of the sound and the resonance.
