In the world of dialogue recording, you need clear and precise audio without any interference; hence, employing background noise removal tactics is necessary.
You see, the slightest distortion can make it challenging to comprehend what is being said; in turn, engagement and retention are lowered.
However, capturing flawless audio is tricky without the right tools and techniques.
In this guide, we will explore how you can remove background noise. Regardless of the content you want to create, crystal-clear dialogues are necessary.
So, let's delve into the world of background noise removal and unlock the potential of your audio content.
What is Background Noise?
Broadly speaking, any noise that distracts from the main dialogue falls under the umbrella of background noises and needs to be eliminated from the file.
Therefore, background noise removal is necessary to ensure your audience resonates with the content and that self-generated transcriptions are accurate.
How do you Remove Background Noise?
Keep reading to learn about six ways to remove background noise:
1. Reduce the Distance Between the Speaker and the Mic
The best way to reduce the speech-to-noise ratio is to ensure that the subject is as close to the mic as possible. This will block background noises and guarantee crystal-clear audio.
2. Use Equalization Techniques
Equalization is simply an adjustment of varying levels of frequency bands within an audio signal. This modification gives you the perfect balance to ensure high-quality audio.
As our ears detect a specific range of frequencies, using equalization can adjust those frequencies to clean the audio.
3. Compression
Although compression does not directly remove background noises, it can mitigate them.
Furthermore, by using compression, you can reduce the dynamic range of sounds to ensure that softer sounds are easily heard. In contrast, the louder ones are lowered to not overwhelm the audio – achieving the perfect tonal balance.
4. Using High-Quality Directional Mics
A high-quality noise-cancelling mic can prevent background noise from creeping into your recordings.
These mics have in-built sensors that continuously detect background noise, which is then turned into 'anti-noise' signals, which are automatically canceled out.
Another way is to position mics in a way that the source of noise is at a distance from the most sensitive part of the mic.
You can also opt for dynamic mics as they are much less sensitive than traditional ones, limiting background noise in videos and audio.
5. Using Built-in Tools For Windows
Windows offers a feature to help in background noise removal. This can be found in the Hardware and Sound section of the Control Panel.
Using it, you can choose your recording device and set the "boost" levels per your device requirement.
You may also have the option of 'noise suppression,' which can further help remove background noise.
6. Using AI Software for Background Noise Removal
Some AI-powered software provide quick and free background noise removal. Your uploaded file is processed within seconds, and all disturbances are removed.
