If you are into creating podcasts, music or videos, you probably know how important it is to have a clear and crisp audio. However, background noise can often ruin the quality of your recordings. If you’ve ever recorded a podcast or a video and noticed distortion, pops, or other unwanted sounds, then you know just how frustrating it can be. Thankfully, there are ways to remove background noise in Audacity. In this article, we will discuss how to remove background noise in Audacity, so you can produce high-quality audio files.

Step 1: Identify the noise

The first step to removing background noise in Audacity is identifying the noise. You need to listen carefully to your recording and determine what type of noise is present. Is it static noise, hum, or hissing sound? Once you have identified the noise, you will be able to apply the appropriate noise removal technique in Audacity.

Step 2: Select a sample of the noise

Once you have identified the noise, the next step is to select a sample of the noise. This will be used as a reference point for noise removal. You need to select a part of the recording where only the noise is present without any underlying dialogue or music.

Step 3: Go to Effect menu and select Noise Reduction

After selecting the sample of the noise, next, you have to go to the Effect menu in Audacity and select the Noise Reduction option. In the Noise Reduction dialog box, you will see various options. You can adjust the noise reduction level, sensitivity, and frequency smoothing. You can also preview the changes to hear the difference in the quality of the sound.

Step 4: Get the noise profile

To get the noise profile, you have to first click on the “Get Noise Profile” button. This will analyze the selected sample of the noise and store the information in Audacity. You only need to do this once per recording if the noise level remains constant. If the noise level changes throughout the recording, you will have to repeat this step by selecting another sample of the noise.

Step 5: Apply noise reduction

Once you have got the noise profile, the next step is to apply the noise reduction filter. To do this, select the entire recording or the part of the recording that contains noise, and then go to Effect > Noise Reduction again. This time, you don’t need to analyze the noise profile but instead apply the settings you previously saved in the Noise Reduction dialog box.

Step 6: Test and adjust

Finally, test the result and adjust the settings as necessary. Play back the recording to make sure the noise has been reduced without losing quality of the speech or music. You can always change the settings and apply the noise-reduction filter again if the noise level isn’t low enough or if the filter is too aggressive.

Conclusion

With Audacity’s noise reduction filter, you can remove unwanted background noise from your recordings quickly and easily. Just make sure to identify the noise type, select a sample, and analyze it to save the noise profile settings. You can always preview the changes and adjust the settings as required. With a little practice and experimentation, you can produce high-quality audio without any distracting background noise.
