The Methods of Voice Recording

- Sep 10, 2018-

1. The human ear has a strong ability to detect between the medium frequency and the medium frequency of 200 to 400 Hz, and the ability to detect high frequency is relatively weak. Therefore, vocal recordings can't be bothersome, and they can be noticed at a glance.

2. Pay attention to the different characteristics of different vocals, should only pick the best vocals.

3. Dental that should be understood: The friction sound generated when the airflow flows quickly through the teeth is very high. Nasal: The airflow path in the mouth is blocked, the soft palate is drooping, and the airflow passes through the nasal cavity, probably at 250Hz. If the nasal sound is too heavy, it will affect the whole, so try to avoid it in the recording. The sound of saliva: The most effective way to make the sound of saliva flowing in the mouth is to let the singer drink water.

4. Microphone selection has no standard, only suitable. Not all vocal recordings are suitable for large diaphragm condenser microphones. For example, a singer lacks high frequency or low frequency.

5. Directivity issues. The lower the frequency, the less obvious is, the higher the more obvious. The directivity of the highest frequency is a straight line that is sent forward along the person's mouth.

6. On the choice and placement of the microphone: vocal recording, usually choose the microphone distance from the singer 20cm, the microphone's diaphragm and the height of the singer's mouth are parallel, according to the actual situation can be higher than the nose parallel or below the mouth 5cm. The left and right off center can reach 2~3 cm. The large diaphragm microphone has warm and wide thickness characteristics and good response from the intermediate frequency. The heart-shaped pointing can effectively isolate all room sounds (the sound reflected by the room). The weakness is that for singers who emphasize medium and high frequency performance, if the high frequency performance is not sufficient, the singer's voice will appear to have no features. Three microphones are usually available, including a warm tube microphone, a neutral universal microphone, and a condenser microphone with a high-frequency response to a small diaphragm. Neutral microphones can hit more than 70% of singers, especially those who have no voice characteristics. In addition, it can also be used for singers whose advantages and disadvantages are too prominent, and which are not well solved. The one-sided understanding of the tube microphone is warm and generous, the transient is not ideal, and the sound is slightly distorted and blurred. But in fact, the high-end tube microphone has little distortion; the sound is still very clear and clear, but with a strong sweetness. So if the right sound can be chosen. The small diaphragm microphone's high frequency response is usually very good, but it is not very good for low and medium frequency response. The mid-low frequency is relatively dim, causing the sound to be cold and bright. In addition it is very sensitive to jetting and toothing. For singers with high frequency, you can try it. Dynamic microphones, in some singers have a big voice, but also want to retain this dynamic, the condenser microphone will be more difficult, and this time you can consider the moving circle. But you should pay attention to the near-talk effect, that is, the closer the sound is to the microphone, the more pronounced the low frequency. The near-talk effect can increase the warmth of the sound, but too much will give people a sense of separation of sound, which may sound uncomfortable. So you should have a good degree of control.

7. Acoustic environment: For studios with poor acoustic environment, such as some family styles. The low-frequency processing is very bad, so that the sound is not only unclean, but also has a more serious resonance or even "overlap". In such an environment, the best choice is heart-shaped pointing. If you are worried about the frontal reflection, you can use a quilt on the back wall, so the reflection can be weakened. For sheds with good acoustic environment, omnidirectional microphones can be used. The sound will be more natural and wide. The advantage of omnidirectional is that there is no obvious close-up effect. The change of singer position does not affect the sound. In addition, using the moving circle to record multiple levels of multiple vocals, the effect is also very good.
