Specific treatment means:

To attenuate LF: attenuation around 100Hz near 6dB, maximum attenuation to 10dB.

For MID: upgrade 250Hz-2kHz in 3-6dB. 250Hz-2kHz is an important band of language.

HF:6KHz above the band attenuation of 3-6dB, in order to reduce high-frequency noise.

Moderator microphone do not use the effect of the processor for reverberation (REV) and echo (ECHO) processing, otherwise you will lose the sense of reality and intimacy.

2 tuning in to ordinary people

In the hall, there are some singing enthusiasts and amateur singers, some people are only amusement activities, many of them own concert. Some people have not received professional training, lack of singing skills, even the noise is not good and will not use the microphone, among them, male and female prone to throat hoarse, prone to breath noise and vocal noise.

In order to eliminate the above phenomenon, the following concrete measures.

To remove the following 100Hz to eliminate low-frequency noise, so that more pure tone.

In 500-800Hz to a small amount of attenuation, so that the tone is not too stiff.

3-6dB in the MID band to enhance the brightness, so that the sound clear, bright;

The average person has a low voice, and a lack of loudness, so the volume should be opened a little larger; can also increase the frequency range of 200-300Hz to increase the loudness of the sound.

Amateur singer dynamic range is not big, do not use automatic volume control.

3 tuning for professional singers

The cabaret is often a professional singer, friends were invited to the cabaret guest, sometimes sing two songs for friends and entertain guests. A professional singer with a loud voice, from the voice, sigh, enunciation, singing with basic skills has a certain level, and each has a certain style of singing.

Tuning requirements:

To understand the characteristics of the singer's voice, network genre, high, medium and low overtone characteristics;

To understand the singer's range and dynamic range;

To be familiar with the songs, lyrics feelings, tune the basic skills in the morning to be consistent with the mood of the song municipality;

Pay attention to the style of the song and the singer's emotion;

Microphone to high grade: broadband sound, small distortion, large dynamic.

Actors stand in the music world, the use of music sound field, so that both the sound of the electronic sound, there are natural sound. Therefore, the requirements of the music has good acoustic properties.

Female voice: the female voice in the high frequency part is easy to produce S sound (Si Sheng); in the 7-10KHz attenuation of 3dB, can eliminate the S tone.

Male voice: male vocal range lower than the female voice of a 8 degree interval, the frequency of a low frequency doubled, 100Hz attenuation in the 3dB or so, can increase clarity.

They are not a single tone, but a complex sound, whether it is a voice, a song, or a musical instrument. It is composed of the pitch of sound and a series of overtones. These overtones are the fundamental frequency of the number of bits, called the division of sound physics, electro acoustic called harmonic, the music is called overtone. It has a very important influence on the characteristics of timbre. The frequency curve of the overtone number and amplitude of the different overtone super tone. This curve on the body and then the performance of the tone. For example, the piano's bass frequency is 27.5Hz, the highest audio rate is 4186Hz, and the piano has more than a dozen overtones, its high frequency up to 10kHx~20kHz, generally can be measured to 16 overtone or 24 overtone. These harmonics can be divided into low frequency overtone, intermediate frequency overtone and high frequency overtone,. If the amplitude of low frequency harmonic tone was strong, thick mixture; if the amplitude of harmonic is relatively strong, sound was mellow, natural and harmonious; high frequency overtone amplitude is relatively strong, sound was bright, clear, strong analytical.

Spectral curve, is the tone of the pan morning amplitude of the vertex in the coordinates of the connection, this package is the color of the spectrum curve.

The spectrum curve of a tone is different, which is different from the material structure, the state and the intensity of the sound and the resonance.

What is the best tone? According to the point of view of Italy bel canto, is the pitch to the intensity of the sixteenth overtone in the coordinates of a straight line, this line is called the best bel canto line, as shown in figure 2. So, the tone of the frequency characteristics of the curve closer to this line, which is the tone of the low, medium and high frequency harmonic proportion is also the most balanced, the timbre of the artistic expression is the best.

In the beautification of the human voice, modification, you can through the mixer above the input channel in the four equalizer, the frequency of sound processing, to improve the timbre of artistic expression. The four segments of the equalizer are divided into the following 4 bands, according to the Berlin Institute of music:

HF:6-16kHz, affect the expressive power of timbre, analytical power.

MIDHF:600Hz~6kHz, affect the brightness and clarity.

MIDHF:200~600Hz affects the tone and force super and strong.

LF:20~200Hz, affect the tone of the mixed thickness and fullness.

If the frequency of high frequency is too weak, the tone becomes color, flavor, personality loss; if the high frequency band is too strong, the tone will become sharp, hoarse, harsh.

If the medium and high frequency of the frequency is too weak, the sound becomes dim, hazy; if the high frequency of the frequency of the strong, the sound will become dull.

If the middle and low frequency of the frequency is too weak, the sound will become empty, weak, soft; if the low frequency of the frequency is too strong, the sound will become stiff, lose vitality.

If the frequency of the low frequency band is too weak, the sound will become thin and pale; if the frequency of the low frequency band is too strong, the timbre will become turbid.

In order to make the timbre beautiful
