If you choose the processing skills of the microphone and vocals according to the type of song
The singing of songs has different styles, different requirements, and different singing skills, so it is also necessary to It requires the sound effects to perfectly express various types of singing of different styles. Bel Canto songs reflect beautiful timbre; ethnic songs reflect national flavor and local color; popular songs reflect deep emotions; and rock songs reflect strong passion. Due to the different styles of songs, the requirements for sound processing are also different.
Microphone selection
1. Bel Canto singing Selection of Microphone
When singing Bel Canto songs, a condenser microphone with a wide frequency response range should be selected and installed on a high microphone stand for long-distance pickup. When singing on the art stage, the distance between the microphone and the mouth shape is generally between 20-60cm. In the grand prix singing, the distance between the microphone and the mouth shape is generally 60-80cm. Its height is above the face and the mouth shape, so that the face can be exposed on the screen. This long-distance pickup has a certain amount of reverberation reflected into the microphone, making the tone thick, natural, bouncy and spacious.
The reason why condenser microphones are used for sound pickup is because the frequency response range of condenser microphones is wide, and the high frequency limit of nervousness can reach 18-20kHz. Because of the beautiful sound of the Bel Canto method, it has a large number of overtones and a high frequency of high-frequency overtones. The high-frequency overtones of treble sounds can reach 10-20kHz. Therefore, it is necessary to use a condenser microphone for pickup. Because this kind of microphone can pick up all the high-frequency overtone components in the singing voice into the microphone and convert it into an audio signal. Due to the high sensitivity of condenser microphones, the microphone cannot be used hand-held. If the microphone is too close to the mouth shape, it will cause the microphone overload distortion phenomenon. Some singers with low sound quality or lack of sound knowledge often do not understand this truth, and blindly pursue the mouth shape too close to the microphone, which causes the loudness to be large, but the distortion also increases, making the early morning color become very poor.
The available microphone models include CRI-3, CRI-5 and CRI-73.
2. Selection of microphones for singing folk songs
The range of folk songs is relatively large, some songs are similar to bel canto style, and some songs are similar to popular songs style, so the choice of its microphones are also different. When folk songs are performed on the art stage, condenser microphones should also be used for sound pickup. However, the distance between the mouth shape and the microphone is closer than that of Bel Canto singing, generally 20-400cm, and slightly lower than the position of the mouth shape. Hand-held dynamic microphones can be used to sing in dance halls.
3. Selection of microphones for singing popular songs
When singing popular songs, hand-held proximity moving coil type with low sensitivity should be used Microphone, because popular songs are mainly characterized by deep emotions, close-talk and close-range pickup methods should be used. This shortens the distance between the source of the song and the listener. From the perspective of listening psychology, there will be a sense of intimacy.
The microphone and the mouth shape are very close to the sound pickup method to pick up a completely real sound. Although the feelings are close, the sound becomes very dry, which requires reverberation (REV) or It is the processing of echo (EVHO). After processing, the sound will become full and thick; otherwise, the sound will appear dry, monotonous, and boring. Therefore, the vocals that sing popular songs must be processed by reverberation or reverberation, so that the singing will become melodious, deep, rich and touching.
Sennheiser e835(S), e845, e855, SHUER SM-58 can be selected for specific microphone models. German Beyerdynamic and American EV are also good brands. There are corresponding models to choose from. You can also choose AKG D-95, AKG D-330, EV N/D-357, EV N/D857, and Japanese triangle brand AT-818, etc.
Several typical singing adjustments
The following introduces several typical singing, and the sound is adjusted in the four-band equalizer on the mixer. Frequency modification and processing methods:
1. Tone frequency adjustment for male singers
The fundamental frequency of male vocals is around 64-523Hz, and the overtone can be extended to 7 -9KHz.
The male singer’s voice is required to be firm, and the timbre to be powerful, but not so blurry. Therefore, the frequency adjustment of the male singer’s timbre requires processing in 4 frequency bands.
According to the overtone structure of the male voice and the frequency spectrum curve, the method of processing male singers in 4 frequency bands is as follows:
(1) Make the 64-100Hz small The purpose is to increase the sense of depth, and it is also the sound range of the bass;
(2) Make a bigger increase at 250-330Hz, because the main frequency of the fundamental sound of the male voice is in this area, so this frequency band is increased. It can increase the strength of the fundamental tone;
(3) Make a small boost to the frequency band around 1KHz, which can ensure the frequency performance of overtones and increase the brightness of the morning color. This frequency band can be extended to 3-8KHz;
2. Tone frequency adjustment for female singers
The fundamental frequency of female vocals is around 160Hz-1.2KHz, and the overtone can be extended to 9-10KHz. Therefore, in order to get the best timbre performance of the female voice, it should be processed on 4 frequencies.
The female voice is round, clear, and bright.
The four frequency processing methods of female vocalists are:
(1) Above 160Hz, the frequency is lower than the female vocal range, and do not enhance the processing;
(2) The 250-523Hz sound range is the main sound range of female voices, and no boosting is performed;
(3) The 1-3KHz frequency band is boosted, the purpose is to make the overtones of the timbre structure show good frequencies The conduction characteristic makes the sound more perfect and at the same time increases the brightness of the sound.
(4) The frequency above 10KHz is given a small boost, the purpose is to make the color of the timbre expressive enough, and to express the tiny and delicate parts of the timbre.
3. Tone processing for severe nasal sounds
There are two reasons for nasal sounds: one is physiological reasons , Physiological organisms are defective; second, the vocalization method or training method is incorrect, resulting in excessive nasal resonance.
To improve the severity and method of nasal sound, frequency processing should be performed on a four-band equalizer, as shown in Figure 3.
(1) Attenuate the 64-100Hz frequency band greatly to eliminate the severe frequency band of nasal sounds;
(2) Attenuate the 100-100Hz frequency band to eliminate the nasal hum;
(3) The 250-330Hz frequency band is slightly improved to increase the strength of the voice;
(4) The 3.3kHz frequency band is greatly improved to increase the brightness of the tone, Clarity,
(5) Make a small boost to the 10kHz frequency band in order to enhance the frequency band performance of high frequency overtones.
The bass frequencies should be cut off for the timbre and processing, which increases the clarity of the timbre accordingly. If a larger boost is made in the 3KHz frequency band, the brightness and clarity of the sound can also be significantly improved.
4. Tone processing for amateur singers with a narrow range
Some untrained female singers have a very narrow range of timbres in the treble region, and the sound Thin, harsh, and lacking depth. Therefore, a four-band equalizer can be used for timbre processing for amateur female singers with narrow vocal bands.
