Whether you are creating your own audio or importing audio files for use, it’s essential to remove background noise and normalize the track for consistent volume. Here’s how to perform noise reduction and normalization in Audacity.
Noise Reduction Process: #
Step 1: Identify Background Noise
Play the audio and locate a section with only background noise (no desired audio). Use the Zoom Tool to zoom in on the silent section for more precision.
Step 2: Highlight the Noise Section
Select the section of audio containing only background noise.
Step 3: Create a Noise Profile
Go to Effect > Noise Reduction and click Get Noise Profile to let Audacity analyze the selected noise.
Step 4: Apply Noise Reduction to the Entire Track
Highlight the entire track by clicking anywhere on the timeline and pressing Ctrl + A (Cmd + A on Mac). Go back to Effect > Noise Reduction and click OK to apply the noise reduction based on the profile.
Normalizing the Track: #
Step 1: Select the Entire Track
Ensure the entire audio is highlighted.
Step 2: Normalize the Volume
Go to Effect > Normalize. Leave the default setting at -1 dB and click OK to run the normalization process.
Step 3: Final Check
The timeline may show slight changes in volume, indicating that normalization has been applied.
By following these steps, your audio will be cleaner and more balanced, enhancing its overall quality.
