Software to separate noise from the human voice or song

Hi all,

IS there any software for Windows 10 to distinguish the sounds in a video or audio file or reduce the noise on that, please?

For audio, you could try Audacity. You can select a sample period where there is just the noise you want to remove, then filter that from the audio.

Noise Reduction can reduce constant background sounds such as hum, whistle, whine, buzz, and "hiss", such as tape hiss, fan noise or FM/webcast carrier noise.... To use Noise Reduction, you need a region in the waveform that contains only the noise you want to reduce.
Be aware that it may be impossible to get a satisfactory removal when the noise is very loud, when the noise is variable, when the music or speech is not much louder than the noise or when the noise frequencies are very similar to those of the music or speech.

Tip

• If there are a lot of different sounds comprising the background noise, you may need to repeat these steps several times in order to create all of the necessary sound profiles.

Thank you for your thorough offer. I will certainly check it out. :)
I was going to give you a thanks rep, but it says you must spread some reputations around before giving it to Bree again! :|

Thanks so much.
How about a similar app for a video file, please? The background sound is on a video file and needs to be removed.
Can I use any of the apps above for removing the background sounds/noises of videos?

You can extract the audio from a video file with the open source command line utility FFmpeg: FFmpeg

A basic command line to do this is: ffmpeg -i input.mp4 audio.mp3

Process the audio, then you can add the new audio back to the video with:

ffmpeg -i input.mp4 -i newaudio.mp3 -map 0:0 -map 1:0 newvideo.mp4


I use this for all my video editing where I need to edit the audio. There are various other switches you can add to the command line to set the audio and video quality (documented in the online FFMpeg manual) but the basic commands should do a reasonable job.

@Bree
Might be silly, but can't download FFmpeg for my Windows 10 x64 machine! Whatever I download is a zip file showing many folders when unzipped without a setup file to install!
How to use that utility to extract sound please?

Sorry about that, I'm sure it use to come with instructions.

You have to do it manually. Basically you extract all the files/folders to a folder of your choice, then add its ...\bin folder to your PATH environment variable. Once you've done that just open a command prompt and type ffmpeg commands and it will run.

I've found this set of instruction for you that goes through the steps in detail.
