(1) Female singer
The frequency of 1.6-3.6 kHz has the most obvious influence on the brightness of female voices. If this frequency is given a certain improvement, its tone will become transparent and vivid.
(2) male singer
The frequency of 150-600 Hz is the main audio frequency and low-level overtone frequency of male songs, which affects the loudness and intensity of the sound. If you upgrade this band, it will make the song become stronger and more resonant. The frequency range of 1 to 3 kHz affects the brightness and clarity of male voices.
(3) Voice
The main frequency of the pitch of female and children's voices is 256-440 Hz; the main frequency range of male voice is 196-315 Hz. If these bands are given a certain boost, it will make the voice look solid and rich.
800Hz is a dangerous frequency of speech, which is the resonance frequency of the throat. Increasing this frequency will make the tone a "hard" and "squeaky" auditory experience. This is a frequency that should be noticed. The sound engineer will raise it to a "dangerous" frequency.
4. Voice modulation of male hoarseness
Due to the physiological structure of the vocal cords, some people, such as teachers, have a hoarse voice in their voices, producing vocal cord noise. In order to make up for this defect, the frequency band of 64-261 Hz can be given a certain improvement, which will make the tone appear thicker, and cover up the hoarse and dry vocal noise to achieve better results.
5. Female voice narrow tone adjustment
Some female singers have a narrow frequency band and a sharp voice. For this tone, the frequency band of 64-315 Hz can be upgraded; the band of 1 to 4 kHz is attenuated, and if processed, the tone will be significantly improved.
6. When the male voice is severe, the tone is adjusted.
When a person makes a sound, the vocal cord vibrates the airflow through the piriform fossa and the throat wall, and enters the oral cavity, the nasal cavity, and the cranial cavity. In this process, resonance of each part occurs. Cranial resonance affects the fullness of low-frequency overtones; nasal resonance affects the fullness of IF overtones; oral resonance affects the fullness of high-frequency overtones; and resonance of the throat is the resonance of IF overtones that everyone has, if this is too strong The throat sound is generated, so that the proportion of the low frequency overtone and the high frequency overtone in the timbre structure is relatively small, and the timbre loses expressive power. Therefore, it is necessary to try to reduce the sounding training of this part of the resonance, and at the same time, the frequency band of 600-800 Hz should be attenuated in the EQ processing, so as to eliminate the serious defects of the throat sound.
7. Tuning of the tone when the nasal sound is severe
Some people may have severe nasal sounds due to the physiological structure of the nasal cavity or due to a cold. It is the tone of some TV hostes, and the phenomenon of serious nasal sounds often occurs. In response to this situation, a large attenuation is performed in the frequency band of 60 to 260 Hz, and a large increase is made in the frequency band of 1 to 2 kHz, so that the definition, brightness, and transparency of the voice can be increased, thereby eliminating the disadvantage of serious nasal sound.
8, when the tooth sound is serious, the adjustment of its tone
Voices that are too strong at 6 kHz can produce severe tones. If the vocal is too strong to be processed by the exciter, this severe tooth tone will also occur. At this point, the intensity of the stimulus can be reduced to alleviate or even eliminate this phenomenon. If it is processed on a four-band equalizer on the mixer, the 6 kHz frequency can be attenuated to reduce the severity of the tooth.
9. When the cough is severe, the tone is adjusted
If the vocal component of the vocal is too strong, the quality of the timbre will be deteriorated, resulting in a distorted effect. Sometimes, when the radio's receiving station's tuning frequency deviates, the vocals will produce a cough-like tone, which is a serious cough. At this time, if the frequency of 4 kHz is attenuated, the phenomenon of severe coughing can be reduced.
The table below lists the effects of the important frequencies of the various sources on the tone.
The above describes the important effects of various sources and their frequencies on the tone. In these respects, if the sound engineer knows a lot and is very clear, then the sound engineer's frequency processing ability for the sound source tone is increased, and the input channel of the mixer's four-band equalizer can be fully utilized, and the frequency characteristics of the sound source can be utilized. Modifications to achieve the best tone state of this source, so that the sound engineer's third-generation creation of the sound is very good, at the same time, the sound engineer also improved its own sound technology level and artistic processing level.
