How to Reduce Background Noise From Microphone?
We just introduced how to perform a background noise removal. But it would be rather ideal if we could minimize background noise during video shooting, saving us time and effort in post-production. Here are some tips to help you minimize background noise during video recording:
1. Optimize The Acoustic Environment
If you are doing in-door shooting or recording, to reduce background noise, you can optimize the acoustic environment by using sound-absorbing materials such as curtains, carpets, foam panels, or acoustic tiles. These materials help minimize reflections and echo, creating a quieter recording space and improving the overall audio quality.
2. Use A Directional Microphone
Investing in a high-quality directional microphone, such as a shotgun microphone, that focuses on capturing sound from the desired source while minimizing background noise, resulting in clearer recordings. Therefore, attach the microphone to your camera or use an external audio recording device.
3. Attach A Pop Filter Or Windscreen To Your Microphone
A pop filter is a mesh screen that is placed in front of a microphone to minimize plosive sounds like "p" and "b" sounds. Windscreens are often made of foam or furry material, reducing wind noise and other air disturbances. These tools are very helpful for reducing background noise.
4. Position The Microphone Close To The Subject
Remember to place the microphone as close to the subject as possible without interfering with the shot. This helps capture clear audio from the intended source while reducing ambient noise. If you cannot afford equipment to reduce background noise, at the very least, make sure to prioritize this point.
5. Be Mindful Of Clothing Noise
When recording or shooting, it is recommended to wear clothing made from materials that are less likely to generate unwanted rustling or scratching sounds. Opt for fabrics like cotton, microfiber, or silk. Avoid wearing clothing with rough textures, sequins, or accessories that can cause disruptive audio artifacts.
If your video already has unwanted background noise, use PowerDirector to remove it effortlessly with just a few clicks!
When Should I Remove Background Noise From Video or Audio?
Here are some situations, where a clean and clear background is of utmost importance, making it crucial to remove background noise:
- Professional Interviews: When conducting interviews for documentaries, news segments, or corporate videos, background noise removal is essential to ensure the clarity of the subject's responses and maintain a professional atmosphere.
- Film or Video Production: In the world of filmmaking, background noise removal is crucial during shooting to create a seamless and immersive experience for viewers. The audience can fully engage with the story and dialogue by minimizing noise distractions.
- Podcasts and Voiceovers: In audio recordings for podcasts, voiceovers, or narrations, background noise removal is vital to deliver a clean sound. Clear audio enhances the listener's experience and allows them to focus on the content without being distracted by unwanted noise.
