Check the recording environment.
Firstly, choose a quiet recording environment if possible or install soundproofing equipment. You can reap the benefits of better audio quality while avoiding disturbing others.
You can start by trying the following points:
• Close windows and noisy appliances are on the street level.
• Make sure the room is well insulated.
• Communicate in advance or stay away from noisy roommates, colleagues, or neighbors.
• Fill with sound-absorbing materials such as soft furniture, curtains, and carpets.
Pre-record ambient sound and reduce noise.
Next, you need to pay attention to noises that often occur in a quiet room but are usually overlooked, such as the sound of the air conditioner or birds chirping. At this point, you can use a recording device to record a 10–20 seconds video of the quiet room as if you were doing an actual recording. Then, check the background audio and note any avoidable noises for future adjustments. If the recording results in you hearing a humming sound from the recording device, it may be connected to the same line as other electrical power-consuming appliances.
To Remove Background Noise During the Recording
Reduce the distance between the microphone and the speaker
How else can I remove the noise in the recording background once the ambient base has been adjusted? For example, you can make the microphone closer to the speakers or move closer to the microphone when you talk to reduce the noise in the background due to the distance of the recording.
Replacement of better recording equipment
If you are a professional, you may also want to consider replacing your recording equipment with better sound quality. Using a dynamic microphone can improve the voice-to-noise ratio, and some recording software has built-in noise filtering tools that can actively remove some noise in the background while recording.
