Sound engineer to make a good sound necessary professional knowledge of three: timbre

In addition to the obvious ability to distinguish loudness and tone, the human ear can also accurately judge the timbre of the sound. Different instruments have very different frequency compositions, for example, violins and pianos even play the same high notes

Notes, people can still quickly tell which is the sound of the piano, which is the sound of the violin, without confusing each other. This is because when they play the same notes, although the pitch is the same, it is

Their harmonic components (overtones) are very different in number, frequency, and intensity.

It is the different composition of these harmonics that gives each instrument its unique timbre. Timbre is mainly related to the frequency structure of sound. In fact, most of the vibrations of Musical Instruments are not simple

Harmonic vibration is composed of many different simple vibrations superimposed, and the vibration frequencies of these simple harmonic vibrations meet the integral multiple relationship. Among them, the lowest frequency is called the fundamental frequency, and the fundamental frequency pairs

Simple harmonics are called fundamental waves, and simple harmonics whose frequencies are integral multiples of fundamental frequencies are called harmonics, and are called overtones in musical vocabulary. It is precisely because of the different components of harmonics that various Musical Instruments and human voices are endowed

Unique timbre. If there is no harmonic component, a simple pitch harmonic signal is not musical.

In the process of sound transmission, in order to make the sound realistic, it is necessary to maintain the original timbre as much as possible. If certain frequency components in the sound are amplified or reduced, it will cause a change in timbre. Sometimes for something special

In particular, it is possible to use the equalizer to make appropriate adjustments to the timbre. It can be seen that the equalizer can make some necessary modifications and adjustments to the timbre. This is another important basis for the use of equalizer.
