Background noise while recording is a common problem everyone has to deal with at some point. iPhones don’t have the best microphones, so most people who want to do an audio recording of value turn to an external microphone.
Unfortunately, not everyone takes their audio recording that seriously, especially non-professionals. However, I can guarantee that if you are recording a podcast on iPhone or just video recording in a noisy place, you will end up with unwanted background noise from wind, background music, white noise, electrical hum, people talking, or a ceiling fan.
iPhones Offer High-Quality Video with Low-Quality Audio
One way to avoid these background noises is by shooting or recording in a professional studio with a dedicated audio recorder. But usually, people who have access to professional studios don’t shoot or record with an iPhone. iPhone cameras are great and even rival professional cameras, but their sound quality is usually very lacking for video recording.
Many users who use their phones for footage find it annoying to have super high-quality video clips, only to hear rumbles and random background noise. So naturally, many of them wonder how to get rid of background noise as cleanly as possible.
Everyone knows a well-rendered video on an iPhone is going to have disappointing sound due to unwanted background noises. What they don’t know is that you can remove unwanted background noise from video without new equipment or complex video editing software.
If you have a video on your iPhone that you can’t use because of the background noise, or you just want to reduce the noise in your future iPhone recordings without buying an audio recorder, then this article is for you.
How to Remove Unwanted Background Noise from iPhone Video
There are many ways to remove background noise from an iPhone video to achieve better audio quality, but they can be broadly described in two ways:
- Using the inbuilt provisions of the iPhone
- Installing a third-party audio editing app.
How to Reduce Background Noise in iMovie App
If you recorded your footage with the iMovie app, the noise reduction process is just as straightforward. The iMovie app has a few built-in audio filters, including a noise removal tool with an user friendly interface.

How to Use iMovie's Noise Reduction Tool:

- There’s also an equalizer which, if you know what you’re doing, can reduce background noise.

Try to Capture More than One Video Clip and Edit them Together
Alternatively, you can try listening to your audio track using headphones (preferably noise cancellation headphones), as they can help block out some background noise from video. A particularly useful way is to capture your video clips with your iPhone and the audio with an audio recorder and then splice them together when you're audio editing.

Adjust the Volume
You can also try turning down the track volume. The overall audio quality is generally worse when listened to at maximum volume. Also turning your video up too loud can introduce some white noise.
How to Remove Noise Using iPhone Apps
The native ways to remove background noise are useful to an extent, but if you want to remove background noise to a meaningful level, you'll need to get a third-party app.
Luckily, there are a lot of these third-party apps. Many of them come in a package like normal audio editing tools, but some are really just specialized noise removal apps. These apps can all be found on the app store, so all you have to do is download and install your best app, edit the audio track or video clip, and then upload to your gallery or direct to whatever platform you want it.
We'll cover here a few of these apps, after which you can get rid of all the troublesome noise in your work and improve audio quality.

Filmic Pro
Filmic Pro is one of the most popular third-party apps for noise removal. Filmic Pro is a mobile app designed to take you as close as possible to professional movie making.

However, the focus here is on its audio output.
Filmic lets you decide which of your iPhone's mics you intend to use and how you want to use it. You can adjust settings to use an external mic. The app also offers a host of features that we are interested in, including automatic gain adjustment and smooth voice processing. Automatic gain control lets you avoid things like clips and distortion that can cause unwanted noise, while the voice processing feature highlights the important parts of the audio track and relegates noise to the background.
Filmic Pro is more popular for its other visual features, but the most powerful of them require an in-app purchase. The sound editing features, however, do not. So you can be assured you’ll get the help you need for your audio with the free version.

Conclusion
Wind noise, rumbles, unwanted background music, and other sources of background noise must be dealt with if you want to record on a meaningful level. The background noise challenge is greater when you’re recording with a device with a weak microphone like an iPhone.
To tackle background noise before you post your video online, it’s best to prevent it in the first place by adequately preparing your room for audio recording. However, most of that is beyond our control, and most times we’re stuck trying to reduce background noise that’s already there in our video file. The guide above discusses a few easy ways and a few useful apps that can get it done.
