Here are two videos made by same person.

The first one comes with some kind of background noise that sounds like microphone or computer fan while the other doesn't.

Considering the videos are not made by me, how do I determine if it is microphone white noise?

How do I get rid of that background noise from the video file that I download from the link above?

  • Get rid of it, or eliminate it before it goes on the recording? One way for the former would be to use a graphic eq., and re-record defeating that particular frequency. Trouble is, then anything else at that same frequency will be defeated.

  • @Tim Thank you. I just updated. I'm trying to get rid of that background noise from the video file that I download from the link above

  • @Tim the problem with EQing away noise is that it's not a single frequency but wide range.

  • There's a great analog tool, the Burwen Dynamic Filter ( sold under other names from maybe 1970 to 1985 or so) but it depends on having an analog stereo input. I don't know any way other than a steep passband filter to remove white noise. Apr 26, 2022 at 13:08

The trouble with this type of issue is it's very easy to make in the first place [stick a really cheap computer headset straight into the headset jack on a PC], but really difficult & expensive to fix properly afterwards.

You can remove the noise completely using something like IZotope RX, but what you're left with is still an abysmal mic sound… just without the noise. It's not worth the effort [I know, I just tried it using the above-mentioned really expensive software;)

I checked at IZotope & the Voice Denoise plugin is actually in the basic entry-level version, so you could do this for $£€ 30, but it's not really worth even that, tbh.


You can try a de-noiser program. But 'white noise' mush is the hardest type of noise to analyse and cancel, because it contains such a wide range of frequencies. Anyway, background noise is the least of your problems in these videos. If audio quality matters, re-record the voiceover. If the original voice must be retained, perhaps for historical reasons, just live with the original. Though distorted, it's pretty intelligible, particularly with the subtitles!
