How to improve the sound quality of video dubbing?
01, the use of external microphone
The most effective way to improve the sound quality of video calls is to use an external microphone. The computer's built-in microphone is not designed for high-quality recording, it will make your voice sound very harsh and feel far away, and it will also include other sounds in the room, which usually makes communication more difficult. After using an external microphone, your voice will sound more loud and clear.
There are many different types of external microphones on the market, we recommend the simplest way is to use a USB microphone. The USB microphone can be plugged directly into the computer without using an audio adapter or mixer to connect the microphone.
02, Select the right recording environment
As with any recorded scene, whether it's recording a video tutorial, teaching at home or recording music, it's important to take a moment to think about your environment and how they'll affect the recording.
For example, rooms with hardwood floors, concrete walls or high ceilings, many reflective surfaces can introduce reverberation or echo to the recording, which can make it difficult for the other end of the video call to hear you clearly. Therefore, you need to choose a room with as many flexible packages as possible, such as a room with carpets, curtains or bookshelves. Smaller spaces such as bedrooms and offices are also ideal recording environments.
03, using headphones to monitor
Most USB microphones have zero-latency monitoring, which sends the audio from the microphone directly to the headset, so you can hear your own voice and control the sound quality.
04, put the microphone close to the mouth
You want to make sure the sound is clear and there is no noise, you must place the microphone so that it is close to your mouth. Both the NT-USB and NT-USB Mini are equipped with a desktop stand to hold the microphone. If you want to get full broadcast-grade sound, you can use a studio cantilever or desktop stand such as PSA1 or DS1 to mount the microphone closer to your mouth. But video calls are not necessary, because it is likely to interfere with the person on the other end of the video. When making a video call, you only need to face your mouth to the microphone at a distance of 20 to 30cm to get great sound quality.
05, Mute microphone when not speaking
The last piece of advice we offer you is to mute the microphone when you are not talking, and encourage other callers to do the same. Most video apps are equipped with a mute button for easy operation, which can switch the sound with one key.
If everyone on the call obeys this rule, background noise, such as the sound of moving chairs, the sound of tapping tables, the sound of air conditioning and outdoor traffic noise, will be greatly reduced. If there are more than two people involved in the call, this ambient noise will distract the caller and make the call sound very harsh.
As long as you adopt these suggestions, you can significantly improve the sound quality of video calls and video conferences, which will completely change everyone's call experience and turn the noisy call process into a relaxed and smooth call experience.
