Part 1. How to Use Audacity to Remove Background Noise

Audacity is a popular audio editing program that is free and open-source. It's commonly used for different audio tasks, such as getting rid of background noise. While Audacity doesn’t specifically have a feature called 'background removal' for isolating or removing music and background sounds from vocals, it does offer tools for noise reduction and certain types of audio isolation.

Here’s how you can use it:

Or, you can record an audio file in Audacity directly to capture the sound you want to keep. (Audacity won’t record?)

• Identify a section of your audio that contains only background noise (e.g., silence with a faint hum).

• Highlight this portion by clicking and dragging over it.

• Menj Hatás > Noise Removal and Repair > Zajcsökkentés.

• Kattintson Get Noise Profile. Audacity will analyze the sample to create a noise profile.

• Highlight the entire audio track or the section you want to clean.

• Return to Hatás > Noise Removal and Repair > Zajcsökkentés.

• Adjust the following settings:

1. Noise Reduction (dB): Determines how much noise to remove. Start with 12 dB.

2. Sensitivity (dB): Adjusts the level at which audio is recognized as noise. Try a value between 3 and 6.

3. Frequency Smoothing (bands): Helps avoid distortion. A value of 3 is a good starting point.

• Kattintson rendben to apply the changes.

Once the settings are done, export the audio file from Audacity by clicking Export > Export to Computer, then make the output profile like name, destination, format, sample rate, encoding, etc.

Then click Export to save the audio file with background noise reduction.

To achieve the best results with Audacity noise reduction, consider these tips:

• Choose a Clean Noise Profile: The cleaner your noise sample, the better Audacity can distinguish between noise and desired audio.

• Avoid Overprocessing: Excessive noise reduction can make your audio sound robotic or distorted.

• Experiment with Settings: Each recording is different, so test various values for Noise Reduction, Sensitivity, and Frequency Smoothing.

Audacity is free, easy to use, and customizable settings.
