I want to be a sound engineer.

Have a certain understanding of audio equipment! In fact, this industry involves a wide range of knowledge! Architecture, acoustics and musicology are just three main parts! You should be interested in this industry! Have simple equipment maintenance and repair skills! Have a certain grasp of the moderate adjustment of music! Many sound engineers and Andhadhun often find it difficult to operate when faced with a wide variety of sound equipment. Now introduce some tuning operation skills to readers. The human ear is sensitive to timbre and can directly judge whether the sound is realistic or not. Poor timbre processing will not only make the sound monotonous, but also cause serious distortion in musical instruments or singing, so the importance of timbre processing can not be ignored. For male voices, most people's voices are low and lack high notes. In order to improve the clarity of singing, the frequency of 3kHz can generally be compensated; For a female voice, there are too many high notes and the voice is "sharp". In order to make the sound loud and not too harsh, the frequency component of 400Hz can generally be compensated.

How to adjust reverberation time

Reverberation usually determines the length of reverberation and has a direct impact on the color and clarity of sound. Under normal circumstances, when singing bass, the reverberation time can be adjusted shorter to improve the clarity of the sound; If the soprano is singing, the reverberation time can be appropriately extended to increase the color of the sound. For the concert venue, if the walls around the room are wooden, the reverberation time should be reduced to avoid the sound blur; On the other hand, if the walls around the room are made of wood, the reverberation time should be reduced to avoid the sound blur; On the contrary, if the room is hung with sound-absorbing materials such as flannel curtains, the reverberation time in such a room should be increased to avoid dry sound. In addition, the number of spectators and listeners also has a great influence, because the audience's clothing also has a great sound absorption effect. Therefore, the sound engineer and Andhadhun can choose an appropriate reverberation time between 1~2 seconds.

How to adjust the proportion of direct sound and reverberation sound components

A complete direct sound without reverberation can't improve and beautify the sound, so it is usually only used for speeches or readings in meetings. Appropriately increasing the proportion of reverberation sound components is conducive to simulating natural reverberation sound, making the sound full and beautiful, and increasing the three-dimensional sense of listeners and spectators. The complete reverberation sound without direct sound component output will make the sound "stained" and cause serious distortion, that is, it is as vague as the sound heard in the bathroom and bathhouse, which is called "bathroom effect" by the insiders. Therefore, in the case of no special requirements, the knob can be adjusted to the middle position, that is, the ratio of direct sound component to reverberation sound component is 1: 1, so that the sound will not be distorted and has a certain reverberation effect.

How to adjust the microphone volume and the proportion of accompanying music

A good song needs 40% music and 60% singing. If the singer's timbre is good, the weight of some accompaniment music can be appropriately reduced to highlight the singer's singing skills. If the singer is not familiar with the melody of this song, it is easy to sing out of tune and not close to the beat. In order to cover up these shortcomings, we can appropriately increase the weight of some accompaniment music at this time. However, in the specific operation, we should be careful not to turn the microphone too loud and not to sing at a volume much higher than the accompaniment music. As a result, the accompaniment sound is too weak, and most of the time only the singer's voice is heard, as if a person was singing there and lost the karaoke atmosphere; But we can't let the accompaniment sound be too strong, which will "drown" the singer's singing skills. It sounds as if the band is playing music and can't understand the singer's interest.

How to Adjust the Tone of Accompaniment Music

Accompaniment music is played according to the timbre of the original singer and cannot adapt to the noise conditions of each singer. For example, some original singers have a high range, while others have a low range. In order to make the accompaniment music take care of the noise characteristics of each singer, the sound engineer and Andhadhun should have a sensitive auditory response to the singer's voice characteristics. When singing, first put the tone control in the middle position, since it will not rise or fall. At the beginning of a song, if the singer is up-regulated, there is no need to adjust; On the other hand, if the singer feels that the bass area can't keep up, or the treble area can't keep up, he can adjust the transmission tone to the sound area that the singer adapts to according to the actual situation.

Tuning is an artistic operation process, which requires Andhadhun to have a good sense of music and understanding, a high musical accomplishment and a sensitive auditory response to the scene at ordinary times, so that the tuned sound can be accepted by the audience.
