If there is any noise-producing equipment in the room that is not related to recording and radio, please turn it off.
Generally, indoor noise-producing devices include electric fans, air conditioners, or air purifiers. The noise of these devices will affect the recording quality. Your audience doesn't care if you are too hot or too cold. What they care about is that they can clearly receive the information you want to convey and have a good listening experience.
Take full advantage of microphone directivity
Place all equipment that cannot be shaken off but that produces noise in the blind area of the microphone.
Each microphone has its own unique directivity, and has different reception effects for sound sources from different angles. In an environment where a person speaks and records in front of a microphone, a cardioid pointing microphone is usually used to face the speaker. At this time, behind the microphone is a blind spot (poor reception).
If you have a very noisy live broadcast equipment (such as a computer fan), you can move the microphone so that the back of the microphone becomes the noise source of the computer fan, which can greatly reduce noise interference and make recording smoother and better.
Keep the microphone as close to the mouth as possible
If you are recording in a room that has not been acoustically treated, try to be as close to the microphone as possible. This can greatly reduce the echo in the room.
The main source of echo is the sound of your speech, which is reflected back through a smooth and hard surface and picked up by the microphone. Echo can be very effective in recording of certain types of music, but it is usually very disturbing in recorded dialogue.
The main function of the microphone being close to the mouth is to improve the signal-to-noise ratio, that is, the direct sound received by the microphone from the mouth will be much larger than the echo received from the room.
Keep the microphone away from the surface of the table
If you are simultaneously playing the computer keyboard or pressing the mouse during a live broadcast or video conference, place the microphone on a separate microphone stand and keep the microphone away from the source of these percussive sounds.
Most entry-level USB microphones come with a desktop microphone tripod when purchased. Although it is very convenient to use, it is not ideal for people who can type on a desk or use a mouse. Using overhead or independent microphone stands, keeping the microphone away from the desktop will reduce the noise of these keyboards and mice, and improve the listening quality of the audience.
Free blowout prevention technology
If you don’t have the budget to buy an explosion-proof filter, you can move the microphone from directly in front of you to a 45-degree angle and aim the microphone at the corner of your mouth. This can greatly improve the spraying effect of wheat.
