Always remember that the audio that you record is going to be part and parcel of your video (unless you remove it) – and that makes its quality important. In particular you need to find ways to reduce the background noise that is picked up in the recording, and can make it crackle, pop, or disrupt the actual audio that you want viewers to hear.
While there are many ways to reduce background noise, initially you should try to:
- Use an external microphone
If you rely on the built-in microphone in your camera or smartphone, it is going to be very difficult to limit the amount of background noise that is picked up. Instead you should use an external microphone, preferably in a mid-range of higher model.
- Use the right type of microphone
Keep in mind that microphones come in many different types, and the right type of microphone can help to dramatically reduce the amount of background noise that is recorded. For example a shotgun microphone that only picks up audio from the area that it is pointed at is likely to record a lot of the other background noise that may be around.
- Turn off electrical appliances that emit sound
Honestly you’d be surprised how much background noise comes from everyday electrical appliances such as refrigerators, air conditioners, fans, computers, and so on. Essentially anything that has a motor in it should be suspect – but to be safe you may just want to switch off anything that you aren’t using.
- Make sure the microphone doesn’t move
Another common source of background noise stems from the movement of the microphone itself. When the microphone moves the surrounding air may rustle against it, or it may brush against a surface. Depending on the type microphone you’re using you may want to place it on a stand, mount, or clip it on in some way to prevent movement.
- Soundproof the room
If you’re going to be recording audio for videos regularly, you may want to try your hand at some DIY soundproofing. While you don’t need to build your own audio production studio, simple steps such as covering the floor with rugs and draping curtains on the walls and windows can go a long way to reduce the background noise.
Despite these steps, some background noise may still make its way onto the audio track in your video – however it should be diminished so taking care of it in post-production shouldn’t be an issue. For example you could use Movavi Video Editor and follow the steps at www.movavi.com/support/how-to/how-to-remove-background-noise-from-video-and-audio.html to remove the leftover background noise.
Make no mistake if you’re able to reduce the amount of background noise, it will improve both the audio quality as well as the overall quality of your video – and make it look much more professional. Regardless of which steps you choose to take, be sure to test the audio recording beforehand so that you can spot whether or not there is excessive background noise present.
