Part 2. Additional Techniques for Reducing Background Noise

Besides using the iMovie remove background noise feature, there are other actions you can take directly to control background noise in videos. Different video editor software types include these features that you can utilize to adjust background sound.

1. Use audio filters to target specific frequencies.

Another tactic you can utilize is using the feature of audio filters. The advanced function is useful for adjusting audio tone and removing frequencies from tracks with better precision. These filters are used for isolating the frequency range in an audio track and then enhancing the level of this frequency.

With this feature, you can increase the low-end frequency response or treble-frequencies in tracks, as you need. However, this process is better suited for more experience editing experts to understand and adjust sound effects using this feature.

2. Adjust audio levels and balance to reduce unwanted sounds.

Users can utilize high-grade video editing software like the iMovie background noise reduction program. With this feature, one can remove unwanted sound effects and fluctuations easily.

Besides that, you can adjust the sound levels to control the quality of the existing audio track and only reduce the extra noise. The best editors include a wide variety of volume range for this balancing process.

3. Record audio in a quiet location with quality equipment.

One of the best techniques you can utilize is during the recording process. Make sure that you are present in a location with zero additional audio effects in the background, like traffic sound, etc. For the best results, going to a well-designed, soundproof studio room is useful if you have the means to get such an area.

Besides that, invest in high-quality audio recording equipment that will record only the music and vocals the microphone captures. Check if the audio recording quality is crisp during the purchasing period.
