Vocal recording and processing

　　1. Adjust the tone frequency of male singers

　　The fundamental frequency of male voice 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 (www.gae-pro.com) requires processing in 4 frequency bands. According to the overtone structure of the male voice and the spectrum curve, the male singer is processed in 4 frequency bands. The method is:

　　(1) A small increase in 64-100Hz is aimed at adding a sense of richness, which is also the vocal range of the bass;

　　(2) Make a bigger boost at 250-330Hz, because the main frequency of the male voice's fundamental tone is in this area, and raising this frequency band can increase the strength of the fundamental tone;

　　(3) A small increase in the frequency band around 1kHz can ensure the frequency performance of overtones and increase the brightness of the timbre. This frequency band can be extended to 3-8KHz;

　　(4) The frequency band above 10kHz can be flattened.

　　2. Adjust the tone frequency of female singers

　　The fundamental frequency of female voice is around 160Hz-1.2kHz, and the overtone can be extended to 9-10kHz. Therefore, in order to obtain a good timbre performance of the female voice, it should be processed on 4 frequencies, and the timbre of the female voice should be round, clear and bright.

　　The four frequency processing methods of female vocalists are:

　　(1) Above 160Hz, the frequency is lower than the female voice range, and no enhancement processing is performed;

　　(2) The 250-523Hz sound range is the main sound range of female voices, and it is processed to increase the strength and fullness of the fundamental sound, which is the low-mid range of female voices;

　　(3) The purpose of improving the 1-3kHz frequency band is to make the overtone of the timbre structure show good frequency conduction characteristics, make the timbre more perfect, and at the same time increase the brightness of the timbre;

　　(4) The frequency above 10kHz is given a small boost, the purpose is to make the color of the timbre (www.gae-pro.com) have enough expressive force, which can express the tiny and delicate parts of the timbre.

　　3. Tone processing for severe nasal sounds

　　There are two reasons for the nasal sound: one is the physiological reason, the physiological body is defective; the other is that the vocalization method or training method is incorrect, which causes the resonance between the nose to be too strong.

　　To improve the severity of the nasal sound and the method should be frequency processing on a four-band equalizer,

　　(1) Large attenuation is performed on the 64-100Hz frequency band to eliminate the severe frequency band of nasal sounds;

　　(2) Attenuate 100-200Hz to eliminate nasal hum;

　　(3) The 250-330Hz frequency band is slightly improved to increase the strength of the voice;

　　(4) The frequency band around 3.3kHz is greatly improved to increase the brightness and clarity of the tone.

　　(5) A small boost is made 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.
