Additional Tips for Reducing Background Noise

To avoid background noise issues in the future, we recommend checking out the tips below. They'll help you record better videos and reduce the need for background noise removal tools like iMovie. Let's jump to the tips.

Tip 1: Use Audio Filters for Better Noise Removal

Audio filters are advanced circuits that will pick up on specific frequencies, discarding other unnecessary elements. These features can remove audio distractions and background noise efficiently and precisely, delivering the most professional results. You can isolate the frequency range, thus dealing with all the audio mistakes.

iMovie provides automatic audio filters, so you can choose between different options to reduce the background noise and deliver amazing results.

Tip 2: Balance and Adjust Audio Levels

Once you start your editing experience, you'll explore the world of advanced features and tools to help you adjust the audio levels and make your video and audio files as professional as possible. For instance, you can select segments of your files, balance the sound, or adjust the audio levels to remove background noise.

You can also mute different parts of a file to remove all possible distractions from the clip. Although this process is more straightforward than the tip above, it still takes time to master. Therefore, be patient on the journey to becoming an audio professional.

Tip 3: Record Videos Quietly

The best technique you can try to make your videos professional is to film in quiet environments. Whether in a home studio or a quiet place outside, that will prevent excessive background noise, and you can quickly deliver the best results. With this strategy, you won't need to use denoisers and background removal tools.

If you don't have a quiet place for recording, you can purchase audio gadgets to make the audio crisp and crystal-clear.


Noisy backgrounds and unnecessary sounds can ruin the quality of your video content. If you think removing these elements will benefit your videography journey and are searching for the best tools on the market, you can try iMovie to reduce background noises.
