For a recording to have good audio quality , it needs to have as little background noise as possible. Background noise is any constant sound which was not intentionally added to an audio recording. The lesser the background noise a listener can hear, the better the quality of an audio recording. This is why noise reduction is a very important part of the finishing process for audio recordings.

Noise reduction is the process of getting rid of any constant background noises or interfering sounds that muddy the clarity of your audio recording or distract from its substance. With noise reduction, you can get rid of constant background sounds like the hum of a machine, the buzz of a fan, whistles, whines, and hisses.

The good news is that with software like Audacity, amateurs and professionals can easily do noise reduction in a few simple steps. In this post, we show you how to easily do noise reduction in Audacity.

Part 1: How to do noise reduction in Audacity

Audacity is a lightweight opensource audio recording and editing software that’s used by many serious podcasters and vloggers. It has PC and MAC versions, and it can be downloaded with an easy-to-read manual. Before you begin the noise reduction process, assess your audio recording, taking note of parts that have background noise and the different background sounds in the recording. You should also form the habit of taking a separate recording of the ROOM TONE. You can know more infomation of Audacity from PCmag review . This recording will provide a clear sample of the background noise in the room and will be very useful in the noise reduction process. See steps below:

• The first step is to create a NOISE PROFILE. This profile tells Audacity the nature of the noise to be reduced or eliminated from the audio recording. To create a NOISE PROFILE, open your ROOM TONE recording and click on EFFECT > NOISE REDUCTION.
• If you didn’t make a ROOM TONE recording, then open the audio file you want to process. Once opened, click and drag over a section that contains mostly noise to select it. Then, click on EFFECT > NOISE REDUCTION.

• Once a new window labelled ‘STEP 1’ opens, click on the ‘GET NOISE PROFILE’ button. This creates the NOISE PROFILE which Audacity will use in the noise reduction process.

• Next, select the entire audio file that requires noise reduction. Then, select NOISE REDUCTION from the EFFECTS tab on the top menu bar.
• When the new window labelled ‘STEP 2’ opens, take your time to enter the settings that give you the desired level of noise reduction. Carefully adjust the bands for NOISE REDUCTION, SENSITIVITY and FREQUENCY SMOOTHING.

• Now, click the PREVIEW button to hear the effect of your noise reduction settings. If you are not satisfied with the preview, you can adjust the settings bars until you achieve a good result.
• You should also click on the RESIDUE radio button to hear the sounds that will be eliminated from your recording if your chosen settings are applied. This can be very useful as some settings can result in the loss of valuable audio content. If you hear valuable audio content captured in the residue, adjust your settings accordingly. Try as much as possible to minimize the loss of valuable audio content.
• Once you are satisfied with your audio preview and residue, click the OK button with the REDUCE radio button selected. This will perform the noise reduction effect on your audio recording.

Conclusion

Keep in mind that noise reduction is not a perfect process and strong noise reduction settings can result in the loss of valuable audio content. Whether you choose to use Audacity or Filmora, try to strike the right balance between getting rid of background sounds and retaining valuable audio content.

Part 1. Audio Hiss: What is it and Why Remove it

A hiss is a broadband noise across the audible spectrum of your audio. It becomes more intense in high frequencies, affecting the quality of the vocals and instrumentals in your audio. A hiss could sound like blue noise and is often caused by the electronic components themselves, which is referred to as self or inherent noise.

A hiss is measured by decibels and is usually difficult to avoid because it is produced by electronic components. You will usually hear the hiss as air that is getting out of a narrow passage. You may also hear a reverb, which is a sound that occurs in space and sends sound waves out in all directions. Since this is a component of the original recording, it is impossible to delete it. However, hiss reduction is possible with the right editing software.

Causes of Hiss in Audio Recordings

• Electronic components such as microphones, video cameras, and interfaces create self-noise because of the heat energy created by the moving parts
• Audio circuits generate self-noise, with the noise floor being the level of the inherent noise in the circuit
• Screening and quality of electronic components, which cheap and poorly made equipment producing more hiss
• Poor-quality audio cables contribute to hiss and hum when they are picked up during recording

Importance of Removing Hiss for a Professional Sound

Removing hiss from audio is important for a professional sound because it makes the sound clearer and polished. The polished sound leads to

• Improved clarity and focus on the main vocals or instruments in a recording sound
• A more professional and smooth sound

Part 4. Tips and Tricks to Avoid Hiss and Reverb Noise

The problem of hissing sound and reverb noise usually comes from the equipment itself. However, some background noise may add to the problem. Making a few adjustments to the recording stage may help in reducing hiss and background noise:

• Optimize the Recording Space

The noise-producing items in your recording space may add to the hissing noise in your audio. While most of the noise may seem innocent, they may amplify themselves when listening to the recorded footage. Optimizing your space before you start, such as closing the windows and doors or turning off your electronic devices will help to reduce the noise.

• Reduce Subject-to-Microphone Distance

Keeping the microphone as close as possible to the subject will drastically improve the speech-to-noise ratio. The microphone will record more of the subject’s voice than the background noise, giving you a clearer audio output.

• Use a Microphone with Gain-Boost

An enhanced gain microphone preamp helps to reduce hiss and notice from the audio in an incredible way. Specifically, the camera’s preamplifier does not add gain because the volume setting is kept low.

• Use Directional Microphones

Usually, microphones signal outside their axis. This is often the case for cardioid polar and short gun patterns. This quality is great for reducing noise when you use directional microphones. The microphone will only focus on what you are interested in, ignoring the background noise.

• Turn Off Camera’s Auto-Gain

The AGC or Auto Gain Control feature is popular in modern cameras. It automatically adjusts the gain for low- and high-volume sounds to make them even. However, it can enhance everything for a quiet setting, causing hissing background noise. Turning the feature off gives you more control over what sounds to focus on.

• Reduce the Number of Open Microphones

Open microphones will continue recording audio even when you are not interested in that sound. Keeping this number low will help reduce hissing sound by focusing only on what you are recording.

Conclusion

Hiss and reverb background noise is an annoying problem. The unwanted sounds affect the quality of your audio and the level of engagement in your footage. While eliminating causes of hiss when recording is the best way to reduce it, sometimes you may notice when it is too late. Using the right editing software will help you reduce the noise and improve the quality of your audio. Wondershare Filmora allows you to do this with the AI Audio Denoise feature.
