![]() ![]() However, if you have real cacophony in the background consisting of both quiet and loud sounds, you might have to apply both the Noise gate and the Median filter. ![]() Whenever the software detects sounds that fall below that threshold, it automatically makes them quieter.įans, ACs, loud PC processors – all these humming, hissing, and buzzing background noises are indeed typically lower than your voice, and that’s why gates are so efficient at removing them. Think of the last video you’ve recorded: its average volume – whether it’s your voice or the sound of music – remains at approximately the same level throughout the entire clip, right? That level is called threshold. However, their parameters must be set individually for each video, and if you want to apply the correct settings, you should understand how noise gates work. You should think of them as real gates or channels that allow certain sounds to pass through and prevent other sounds from getting in. Noise gates are the most common type of background noise removers. How does a noise gate help remove background noise from a video? For loud sounds like pops and clicks, you’ll want to use a so-called “Median” filter.įeel free to watch this video tutorial and read the details below. Gates are particularly efficient at removing noises produced by a working air conditioner, a fan, a loud computer, or any other type of unwanted low-frequency sounds in your video. To remove such background noise from a video, you’ll need to apply an audio filter called “Audio gate” (often referred to as “Noise gate” or “Gate”). In this article, we’ll focus on the first category because it’s more common and trickier. Luckily, there is an easy solution, and it’s available right in the free version of VSDC Video Editor.īackground noises can be broadly divided into two categories: quiet constant sounds and loud sudden sounds. We know that because we struggle with background noises every week while preparing video tutorials for our YouTube channel. ![]() Unless you’re recording videos in a professional studio, it can be difficult to avoid background noises.
