How To Use Audacity To Remove White Noise

There is a bit of a learning curve before you figure out Audacity at its full potential. Follow these simple steps to learn how to use Audacity to remove white noise:

Step 1: Visit the official page of Audacity and download the application on your computer.

Step 2: Go to File. Then from the list of options, choose Import and select Audio from the drop-down menu > navigate to the folder where the audio file is present.

Step 3: After uploading the song to the program, you will have to choose the frequency level you want to extract. You can do this by choosing a bit where the background noise is visible. (Ensure not to select the parts where someone is talking). You can use the Selection tool and drag the section where background noise is audible.

Step 4: After isolating the sound, hover to the Effect section and choose Noise Reduction.

• Choose Get Noise Profile and allow Audacity to determine the frequency to be eliminated from the audio clip.
• Once Audacity determines the frequency, choose the section you want to remove the white noise. You can very well choose the entire clip.
• Hover to the Effects section again and choose Noise Reduction from the list of options.

Step 5. You will have to perform several tweaks like:

• Choose the amount of noise reduction that Audacity should perform (12 decibels should be ideal in most cases)
• Adjust the sensitivity and frequency-smoothing bands as needed. You can leave it to the default setting of six and three if you do not know what you are doing.
• You can use other levers to isolate the noise frequency as per need, but you can stick with default options.

Step 6. After adjusting the levers, choose to preview the clip. In case you are still hearing the background noise, it means the audio white noise removal hasn’t been a success.

• To clear out the background noise, increase the noise reduction measure to 13, 14, 15 decibels, and so on until you get the desired result.
• Once you get the perfect sound, choose OK.
