In the production process of radio programs, it can be said that they are both simple and complex. The simple reason is that there is no need to deal with the picture in the recording of radio programs. The complex reason is that the steps in the recording process of radio programs are relatively complex and there are many details. To produce a good radio program and make the radio program popular, a large number of experienced practitioners need to work carefully, At the same time, it also needs the support of various technologies. So what are the key points and precautions in the production of radio recording? Let's talk about it for you.

The importance of recording in radio programs is self-evident, especially for all kinds of literary and artistic programs, so it should be treated with caution. Through the debugging of recording equipment, the sound of the announcer can be perfectly reproduced, which is the most basic requirement of the recording process. There are some techniques you can use in this process.

1. Pay attention to the selection of recording room and recording equipment. In order to ensure the clarity and reliability of the original sound as much as possible, especially the broadcaster and other sounds in the program, a suitable recording studio must be used to ensure that its reverberation time and mute effect meet the recording requirements. There are various choices of recording equipment, so it is necessary to select recording equipment according to specific recording requirements. The moving coil microphone or capacitor microphone is usually used for language broadcast recording. The moving coil microphone is clear, durable and affordable; Condenser microphone has good amplitude frequency characteristics and high sensitivity.

2. Pay attention to communication with announcers. When you need to communicate with the announcer, you need to inform the announcer of the time and duration of the soundtrack synthesized to the original sound, so that the announcer can understand it. At the same time, you can also play songs and invite the announcer to listen before broadcasting, so that the announcer can enter the broadcasting state in advance, so that his language can have a better overall effect with the music.

3. The control of recording level shall comply with national standards. The control of recording level shall comply with the relevant national standard Gy / t192-2003 full scale level of digital audio equipment. It must be recognized that the level fullness also has a very important impact on the quality of broadcast programs. Too high fullness will cause hearing fatigue or distortion to the audience. If it is too low, it will affect the clarity of the program. Especially in the selection process of various radio programs, we should pay more attention to the full level.

4. Pay attention to the impact of environmental noise and man-made noise. A good recording studio can shield the external noise, but the introduced noise such as equipment noise and line noise is difficult to deal with. In the existing methods, only the recording microphone with excellent performance can be selected, such as the equipment whose audio index can reach class A or the recording microphone with good single directivity.

5. Pay attention to the sound environment in the recording room, production room and hearing room. The sound environment in the recording room, production room and hearing room shall be the same as far as possible. A higher volume shall be appropriately selected during the hearing, so as to control the mixing ratio of music and recording details, and deal with problems in time. The factors affecting the sound environment include indoor environment and equipment. In these two aspects, we should focus on creating a sense of similarity. Otherwise, the hearing after the production of the recording will find that the effect is different from that of the recording, which will hinder the production of the program.
