How to Remove Background Noise from Video using Audacity

Audacity is a free and powerful audio editing tool that can help you reduce background noise in your video. While Audacity is primarily an audio editor, you can easily extract audio from your video, remove noise, and then re-sync the cleaned audio with your video. Here's how to do it:

Step 1Extract the Audio from Your Video

First, you need to extract the audio from your video. You can do this using any video-to-audio conversion tool or by importing the video directly into Audacity if it supports your video format. Once the audio is extracted, open it in Audacity.

Step 2Select a Noise Sample

In Audacity, listen to the audio and find a section where only the background noise is present (no dialogue or music). Highlight a portion of this noise to use as a sample.

Step 3Open the Noise Reduction Tool

With the noise sample selected, go to the "Effect" menu at the top and choose "Noise Reduction." In the window that opens, click "Get Noise Profile." This allows Audacity to analyze the selected noise and identify the specific frequencies causing the unwanted sound.

Step 4Apply Noise Reduction to the Entire Audio

After getting the noise profile, select the entire audio track (click anywhere on the waveform and press "Ctrl + A" to select all). Then, return to "Effect" and select "Noise Reduction" again. This time, adjust the sliders for "Noise Reduction," "Sensitivity," and "Frequency Smoothing" to control the amount of noise reduction. A good starting point is to set "Noise Reduction" to around 12 dB, "Sensitivity" to 6.00, and "Frequency Smoothing" to 3 bands.

Step 5Preview and Adjust

Click "Preview" to listen to how the audio sounds after noise reduction. If the noise is still noticeable or if the audio quality is too degraded, adjust the sliders and preview again until you’re satisfied with the result.

Step 6Export the Cleaned Audio

Once you’re happy with the noise reduction, you can export the cleaned audio. To do this, go to the "File" menu, select "Export," and choose either "Export as WAV" or "Export as MP3" from the options.

Step 7Re-sync the Audio with the Video

After exporting the cleaned audio, you can import it back into your video editing software (like Adobe Premiere Pro, Final Cut Pro X, or iMovie). Sync the cleaned audio track with the original video, and you’re done!

Step 6Use the "Spectral Repair" Tool (Optional)

If there are specific parts of the audio with more severe noise or distortion, you can use the "Spectral Repair" tool. Select the noise you want to repair, and use the tool to replace it with a more appropriate sound.

Step 7Export the Cleaned Audio

Once you’re satisfied with the noise reduction, export the cleaned audio by going to the "File" menu and selecting "Export." Choose the format you prefer (WAV or MP3), and save the file.
