In most cases, recording high-quality audio during shooting is difficult since the dialog is commonly hard to hear or competing with the background hums from the environment, for instance, a dreaded air conditioner or fans.

Method 1: Remove background noise from audio or video directly
Whether you’re removing the background noise from audio or a video, Filmora Video Editor can handle it easily. With this easy-to-use video editor, you can also
detach the audio from the video
, and use the Audio Mixer or Audio Equalizer tools to edit the audio further, and then ExportExport and save your audio as MP3 format. Below are the detailed steps.
: Import your video in the Wondershare Filmora timeline panel. Preview and
trim the video
and delete the parts that you don’t want to keep.
: Detach the audio from the video by right click with the feature “Audio Detach.”
: Double click on the audio track, and select “Remove background noise” in Edit Panel to remove the background noise directly.
You can also just double-click the video clip in the timeline without detaching audio from the video to enter the Editing panel and switch to the Audio tab to edit audio and remove the noise.
: You can also fine-tune the audio with the Equalizer feature to make the audio sounds more natural. If you want to have a better effect, just adjust the audio to fit perfectly the video frame by frame.

Method 2: Hiding Background Noise with music
audio editing software
like Audacity can only well deal with the white noise, which means the constant, predictable, and never changing noise.
But when it comes to other noises like people talking in the background, cars, birds chirping, doors slamming, foot traffic, etc. It’s been nearly impossible to remove them while keeping your audio in good quality. So, we recommend masking them instead of trying to fix the issues, and just
adding some background music to your video
can solve this problem.
In Wondershare Filmora, you can simply drag a song or music in the Music Library into the audio track of your timeline, then edit and adjust its volume, speed, pitch. Then you can cover the background noise without drawing attention away from your dialogue.
Besides the inbuilt music and sound effects, you can also add your own music and audio file from the computer and adjust it accordingly. Then you can export and save the video with the background noise hid in any format you like.

Audacity is a free, open-source, and professional audio editing software available both on Windows, Mac, and Linux. You can use it to record live audio, edit the audio such as cut, copy or paste tools, or do some advanced audio analysis with the Spectrogram view mode for visualizing.

Below are the updated detailed steps about how to remove background noise in Audacity in 2019. Note: You can download and install Audacity audio editing software from its official website for free.
Step 1: Import audio with noise to Audacity
After launching Audacity, go to the File option, and select Open or Import to import the audio or video file into Audacity. Audacity will remind you to make a copy of the audio file before editing. I think this is very caring. However, if you’re importing a video file to Audacity, you may need to download and install FFmpeg Library first. Otherwise, you need to detach the audio from the video or convert the video to audio to compatible formats.
Step 2: Pick up the Noise Segment
To pick up a noise segment,
the track or adjust the Track Size under the View menu to preview the waveform in Audacity more precisely and then select a segment that has pure background noise.
Step 3: Apply Noise Profile to remove background noise
Go to the Effect tab and then select “Noise Reduction”, start with the defaults, and then click on “Get Noise Profile”, so that Audacity will figure out what to filter out based on your selected segment.
Step 4: Adjust settings.
And then, choose the whole audio that needs to remove noise and go back to the Noise Reduction windows again, choose how much noise you want to remove, and then click OK to reduce the noise. You can use the default settings. Audacity will reduce the noise automatically, and you can see the result straight away in the audio track.
Go to Effect and Amplify to fix the muffling of your audio. Click “Preview” to check whether the noise has been removed. If yes, click “OK” and then export the denoised audio to MP3, WAV, or other formats from Audacity.
Reducing background noise in Audacity is totally free, but as we said before, you need to record pure background noise in your audio file so that Audacity can figure out what to remove. The interface isn’t so modern, but it is simple after several practices.
