  1. Understand the source of white noise
    Before attempting to eliminate white noise, it is essential to understand its source. Some common sources include microphones, air conditioning systems, and even electronic devices. Identifying the source helps you take corrective steps in the filming process and improves your chances of successful noise reduction in post-production.



  2. Use iMovie's in-built noise filters
    iMovie has a powerful audio enhancement feature, reducing background noises without affecting other audio components. To use it, follow these steps:




A. Open your iMovie project and select the video clip containing white noise.
B. In the audio inspector window, click on the Audio tab to reveal audio settings.
C. Locate the 'Reduce background noise' slider and adjust it accordingly. Sliding it to the right increases noise reduction.



  1. Use EQ settings to target specific frequencies
    If iMovie's noise reduction filter isn't quite solving the issue, using equalization (EQ) settings can further refine your audio. Locate the 'Equalizer' option within the Audio tab, and select 'Custom.' Experiment with different combinations by adjusting each frequency band, then listen to the audio playback until the white noise is reduced to a minimum.



  2. Record separate audio tracks and overlay them
    Sometimes, it is best to use a separately recorded audio track to overlay the video. This allows you to use high-quality microphones and equipment for better sound capture, bypassing the need to reduce white noise in iMovie altogether. Import your separate audio tracks and position them over the original audio, adjusting the volume levels as needed.



  3. Combine multiple noise reduction techniques




If iMovie's built-in options aren't enough, consider supplementing them with third-party plug-ins and software. Research compatible audio plug-ins for additional noise reduction tools, then experiment with a combination of techniques for optimal results.


In conclusion, getting rid of white noise in iMovie involves a combination of pre-production, in-app settings, and post-production measures. By employing these methods, you can achieve refined audio and elevate the overall quality of your video projects.
