Tuning skills

Many sound engineers and tuner often find it difficult to operate when faced with a dazzling array of sound equipment. Now introduce some tuning operation skills to readers.

    The human ear is more sensitive to the timbre, and it can directly judge whether the sound is realistic or not. If the tone is not handled well, it will not only make the sound monotonous and boring, but also cause serious distortion of the instrument or singing, so the importance of tone treatment cannot be ignored. For male voices, most people’s voices are relatively low and lack treble. In order to improve the clarity of singing, the frequency of 3kHz can generally be compensated extremely; for female voices, the treble appears too much and the voice is “skewed”. In order to make the sound louder and not too harsh, the 400Hz frequency component can generally be compensated.

    How to adjust the reverberation time

    Reverberation usually determines the length of the reverberation and has a direct impact on the color and clarity of the sound. Under normal circumstances, when the bass is singing, the reverberation time can be adjusted shorter to improve the clarity of the sound; if it is a soprano singing, the reverberation time can be appropriately extended to increase the color of the sound. For a concert venue, if the walls around the room are made of wooden materials, the reverberation time should be reduced at this time to avoid blurring the sound; on the contrary, if the walls around the room are made of wooden materials, the reverberation time should be reduced. The time should be adjusted lower to avoid ambiguity in the sound; on the contrary, if the room is hung with sound-absorbing materials such as flannel curtains, the reverberation time should be adjusted longer in such a room to prevent the sound from being dry. In addition, the size of the audience and the audience also has a great influence, because the costumes of the audience also have a great sound absorption effect. Therefore, the sound engineer and the tuner can choose a reverberation time that feels suitable within 1 to 2 seconds.

    How to adjust the ratio of direct and reverberant components

    Completely direct sound without reverberation output can not play the role of improving and beautifying the sound, so it is usually only used for meetings or recitations. Appropriately increasing the proportion of reverberation sound components is conducive to simulating the natural reverberation sound, making the sound full and beautiful, and can increase the three-dimensional sense of the audience and the crowd. Completely reverberant sound without direct sound component output will cause the sound to "color" and cause serious distortion, that is to say, it is as ambiguous as the sound heard in the bathroom or bathhouse. People in the industry call it "bathroom." effect". Therefore, if there is no special requirement, the knob can be adjusted to the middle position, that is, the ratio of the direct sound component to the reverberant sound component is 1:1, so that not only will the sound not be distorted, but it will also have a certain reverberation effect. .

    How to adjust the ratio between microphone volume and accompaniment music

    A good song should be accompanied by 40% of the accompaniment music and 60% of the singing voice. If the singer’s voice is good, the component of some accompaniment music can be appropriately reduced to highlight the singer’s singing; The melody of You is not very familiar, it is easy to sing out of tune, and can not close the film. In order to cover up these shortcomings, you can increase the weight of some accompaniment music. But in the specific operation, you should be careful not to increase the microphone volume too much, let alone singing the volume much higher than the accompaniment music. As a result, the accompaniment sound is too weak. Most of the time, only the singer’s voice is heard, as if a person is singing a cappella there, and the atmosphere of karaoke is lost; but the accompaniment sound cannot be too strong, and the accompaniment will be too strong, and it will be "overwhelmed." "The singer's singing sounded like a band playing music, and I couldn't appreciate the singer's taste.

    How to adjust the tone of accompaniment music

    The accompaniment music is played according to the original singer’s tone. It cannot adapt to the noise conditions of each singer. For example, some original singers have a higher range, and some original singers have a lower range. In order to be able to Let the accompaniment music take care of the noise characteristics of each singer, and the sound engineer and tuner should have a sensitive auditory response to the voice characteristics of the singer. When singing, first put the pitch control in the middle position, since it does not increase, it does not decrease. At the beginning of a song, if the singer can adjust the tune up, there is no need to adjust it; on the contrary, if the singer feels that the low range cannot be sung, or the high range cannot keep up, he can adjust the transmission pitch to the singer’s adaptation according to the actual situation. Sound area.

    Tuning is a very artistic process. It requires the tuner to have a good sense of music and comprehension, a high level of musical accomplishment, and a sensitive auditory response to the scene, so that the tuned sound can be Accepted by the audience.
