How to Remove Noises from Audio in Final Cut Pro

Regarding video editing, high-quality audio is just as crucial as stunning visuals. Unwanted background noise can detract from your video's overall impact. Still, Final Cut Pro (FCP) offers excellent tools to help you remove noise from video and ensure your content sounds as good as it looks.

In this guide, we’ll walk you through removing noise from audio in FCP, ensuring your videos maintain professional-grade sound quality. Additionally, we'll explore how Gling.ai can complement this process for more advanced noise reduction.

Understanding Noise in Audio

Common types of noise include:

• Background Hum: Often caused by electrical interference, air conditioning units, or other equipment.
• Wind Noise: A common issue in outdoor recordings.
• Hiss or Static: Often due to low-quality recording equipment or high-gain settings.
• Room Echo: Unwanted reverberation that can make speech sound distant or unclear.

Learning how to enhance video sound quality by addressing these issues is crucial for professional-grade content.

Step-by-Step Guide to Removing Noise in Final Cut Pro

1. Import Your Video and Locate the Noisy Sections

First, import your video into Final Cut Pro if you haven’t already. Drag your video clip into the timeline and play through it to identify the sections with unwanted noise. You can always come back to this guide to refresh your knowledge.

2. Select the Audio Clip in the Timeline

Click on the audio clip in the timeline you want to clean up. This will activate the clip and allow you to adjust it using the tools available in Final Cut Pro’s Inspector.

3. Open the Audio Inspector

With your audio clip selected, navigate to the “Inspector” panel on the right side of your screen. If it’s not visible, you can show the Inspector by clicking the Inspector icon or pressing Command+4. In the Inspector, switch to the audio tab, shown as a small speaker icon.

4. Enable Noise Reduction

Final Cut Pro includes a built-in “Noise Reduction” feature that can help reduce unwanted noise in your audio. Find the “Audio Enhancements” section in the Audio Inspector and toggle the “Noise Reduction” option to ON.

5. Use Hum Removal (If Needed)

If your audio contains a consistent low-frequency hum, such as from electrical equipment, Final Cut Pro’s “Hum Removal” feature can help. The “Hum Removal” option is in the Audio Enhancements section.

Click to enable it, and you’ll be given a choice between 50Hz and 60Hz. This refers to the frequency of the hum, which often corresponds to the power supply frequency in different regions (50Hz in Europe, 60Hz in the United States). You can also use the slider to fine-tune the effect.

6. Fine-Tune with Equalization (EQ)

While Noise Reduction and Hum Removal are great tools, sometimes you’ll need more control to get your audio right. To access the EQ settings in Final Cut Pro, go to the Audio Inspector and click “EQ.” You can choose from presets like “Voice Enhance” or “remove background noise from video online” or manually adjust the frequency bands to target specific noise.

7. Review Audio and Tweak

After applying noise reduction and EQ, listening to your audio is essential to ensure the noise has been effectively reduced without compromising the overall sound quality. Play through your clip, ideally with headphones, to catch any remaining issues.

If you notice any areas where the noise is still too prominent, go back into the Audio Inspector and make further adjustments. Don’t be afraid to tweak the settings a few times for the best possible result.

8. Use Audio Effects (SFX) for Extra Enhancements

Final Cut Pro also offers various audio effects that can enhance your sound. For instance, the “Compressor” effect evens the volume levels, making quieter parts of your audio more audible without amplifying background noise. To add effects, go to the “Effects” panel, search for the desired effect, and drag it onto your audio clip.

9. Export Your Cleaned Audio

Once you’re satisfied with the noise reduction and overall audio quality, it’s time to export your project. Listen to the final output before exporting; sometimes, issues may only appear in the final render.

To export, go to File > Share > Master File (or your preferred export option), and choose the appropriate settings for your project.

10. Integrate Gling.ai for Noise Reduction

For more complex noise issues or an extra layer of audio refinement, consider integrating advanced tools like Gling.ai into your workflow. Gling.ai uses AI-driven algorithms to identify and remove various types of noise while preserving the clarity and natural quality of the audio.

You can easily incorporate Gling.ai by exporting your audio from Final Cut Pro, processing it through Gling, and then re-importing it into FCP for final adjustments. This combination can help you achieve the highest audio quality possible, especially in challenging environments or with complex noise patterns.

Troubleshooting Common Noise Reduction Issues

You might encounter some common issues when cleaning up audio:

• Over-Processed Audio: If your audio starts sounding robotic or distorted, you’ve likely applied too much noise reduction. Dial back the intensity or adjust the EQ settings to restore a more natural sound.
• Residual Noise: Some noise might be too persistent for simple noise reduction to handle. In these cases, try applying multiple layers of noise reduction or using additional tools like third-party plugins specifically designed for noise removal.
• Balancing Noise Reduction with Audio Quality: It’s a delicate balance between reducing noise and maintaining audio clarity. If you’re struggling to find that balance, consider breaking your audio into sections and applying different levels of noise reduction to each.

Conclusion

Removing noise from audio in Final Cut Pro ensures your videos have professional-grade sound. Whether you’re dealing with background hum, hiss, or other unwanted sounds, Final Cut Pro’s built-in tools make the process straightforward and effective. 

By following this advice and considering extra tools like Gling.ai, you can polish up your audio, improve the overall quality of your videos, and create a more enjoyable experience for your audience. Good audio is vital to video production. Take the time to perfect it and remove filler words to hear the difference.
