How to Reduce Background Noise in iMovie on Mac

Last Updated: Feb 21, 2024 by

Are you tired of hearing background noise in your iMovie videos? Whether you’re recording a vlog, a tutorial, or a family video, background noise can be distracting and take away from the overall quality of your video. Luckily, there are ways to reduce background noise in iMovie on your Mac. In this article, we’ll explore different methods for reducing background noise in iMovie and help you achieve a cleaner, more professional sound in your videos.

Why Is Background Noise a Problem?

Background noise can be any unwanted sound that is present in your video. It can come from various sources, such as wind, traffic, or even the hum of your computer’s fan. Background noise can be distracting and make it difficult for viewers to focus on the main audio in your video. It can also make your video sound unprofessional and lower its overall quality.

The Importance of Audio Quality in Videos

Audio quality is just as important as video quality in creating a successful video. Poor audio can ruin an otherwise great video and make it difficult for viewers to engage with your content. In fact, studies have shown that viewers are more likely to stop watching a video due to poor audio quality than poor video quality. This is why it’s crucial to reduce background noise in your iMovie videos.

How to Reduce Background Noise in iMovie

There are several methods you can use to reduce background noise in iMovie. Let’s explore some of the most effective ways to achieve a cleaner, more professional sound in your videos.

Use the Noise Reduction Tool

iMovie has a built-in noise reduction tool that can help reduce background noise in your videos. To access this tool, follow these steps:

  1. Open your iMovie project and select the clip with the background noise.
  2. Click on the “Audio” tab at the top of the screen.
  3. Click on the “Enhance” button.
  4. Check the box next to “Reduce background noise”.
  5. Adjust the slider to your desired level of noise reduction.

Keep in mind that using this tool may also reduce the overall volume of your audio, so you may need to adjust the volume of your clip after applying the noise reduction.

Use a Noise Reduction Plugin

If the built-in noise reduction tool in iMovie is not enough, you can also use a noise reduction plugin. There are many plugins available for iMovie, such as the popular “Noise Reduction” plugin by CrumplePop. These plugins offer more advanced noise reduction options and can help you achieve a cleaner sound in your videos.

To use a noise reduction plugin in iMovie, follow these steps:

  1. Download and install the noise reduction plugin of your choice.
  2. Open your iMovie project and select the clip with the background noise.
  3. Click on the “Audio” tab at the top of the screen.
  4. Click on the “Effects” button.
  5. Select the noise reduction plugin from the list of available effects.
  6. Adjust the settings to your desired level of noise reduction.

Use a Dedicated Audio Editing Software

If you’re serious about reducing background noise in your videos, you may want to consider using a dedicated audio editing software. Programs like GarageBand or Audacity offer more advanced noise reduction tools and can help you achieve a professional sound in your videos.

To use a dedicated audio editing software to reduce background noise in iMovie, follow these steps:

  1. Export your iMovie project as an audio file.
  2. Import the audio file into your chosen audio editing software.
  3. Use the noise reduction tools in the software to reduce background noise.
  4. Export the edited audio file.
  5. Import the edited audio file back into your iMovie project.

Use a High-Quality Microphone

One of the best ways to reduce background noise in your videos is to use a high-quality microphone. A good microphone can help capture clear, crisp audio and minimize background noise. There are many options available, from affordable USB microphones to more professional XLR microphones. Do some research and choose a microphone that fits your budget and needs.

Use a Noise-Cancelling Headset

If you’re recording audio for your iMovie video, using a noise-cancelling headset can help reduce background noise. These headsets use advanced technology to block out external noise and capture clear audio. They are especially useful if you’re recording in a noisy environment, such as a busy office or a crowded coffee shop.

Other Tips for Reducing Background Noise in iMovie

In addition to the methods mentioned above, here are some other tips for reducing background noise in iMovie:

Record in a Quiet Environment

The best way to avoid background noise in your videos is to record in a quiet environment. Choose a room or location that is free from distractions and background noise. If you’re recording outside, try to find a quiet spot away from traffic or other sources of noise.

Use a Windscreen or Pop Filter

If you’re recording outside or in a windy environment, using a windscreen or pop filter can help reduce background noise caused by wind. These accessories can be attached to your microphone and help block out wind noise, resulting in a cleaner sound in your videos.

Edit Your Audio Clips

If you’re using multiple audio clips in your iMovie project, you can edit each clip individually to reduce background noise. This can be especially useful if one clip has more background noise than the others. Simply select the clip, click on the “Audio” tab, and use the noise reduction tool or plugin to reduce the background noise in that specific clip.

Conclusion

Background noise can be a major problem in iMovie videos, but there are ways to reduce it and achieve a cleaner, more professional sound. Whether you use the built-in noise reduction tool, a plugin, or a dedicated audio editing software, these methods can help you achieve a better audio quality in your videos. Remember to also record in a quiet environment, use a high-quality microphone, and edit your audio clips to further reduce background noise. With these tips, you can create high-quality videos that sound as good as they look.
