Because of the background noise, audio recordings for podcasts or music can lose a lot of quality. Any undesired outside noise that unintentionally makes it into the recording is referred to as background noise. People coughing or slamming doors are examples of background noises that you can, to some extent, regulate. However, noises that are naturally occurring in the environment, like as hiss, clicks, and static, as well as mechanical noises that come from the system itself, are harder to regulate. In general, noise is more likely to affect analog recordings than digital ones.
How to Screen Record Without Background Noise
Installing the microphone on a stand, step one
Vibration can be decreased by mounting the microphone on a stand. If you hold the microphone in your hand, it might record your finger movements while the recording is being made. A microphone stand makes it possible to record hands-free.
Using a microphone pop shield
While being uttered, some sounds, such as “P,” “B,” and “S,” have a tendency to unleash a burst of air, which is very difficult to get rid of once it has been recorded. By placing a pop shield over the microphone, you can get rid of them. The pop shield, which takes away the “pop” of these sounds, is just a circle with a thin sheer cloth stretched across it.
The background noise can be muffled by raising the recording levels. A high input level improves the signal to noise ratio while simultaneously masking the noise. The signals may clip at very high levels, which will result in distortion. In order to avoid distortion and still have enough headroom, set the input level at roughly -6db.
Reduce Subject-to-Microphone Distance, Increase Microphone to Noise Distance
Reducing the subject’s distance from the microphone is the single most effective strategy to increase the speech-to-noise ratio. Imagine a vocalist performing live with the microphone placed directly on or at their mouth. The extraordinarily close proximity of the subject to the microphone can cancel out strong stage levels.
Lavalier mics are frequently utilized to record production dialog in noisy locations for the same reason. Boom-mounted microphones cannot always be put as close to the lips as lavaliers, which increases the speech-to-noise ratio.
Eliminate Background Noise Sources
It is preferable to get rid of acoustical noise sources before recording whenever it is practical. For instance, shutting off a neighboring air conditioner is far simpler than attempting to eliminate the sound during post-production. Similar to this, if there is audible traffic noise, relocating is the best course of action. This is typically easier said than done.
Keeping wind noise to a minimum is also crucial. Wind noise can cause distortions in microphone preamplifiers that may be difficult to remove. Use good windscreens on your microphones, especially if you’re outside.
When using headphones, it is frequently possible to quickly identify acoustical sound sources, such as wind noise, that are otherwise invisible.
Use Directional Microphones
Signals that are off-axis, or outside the microphone’s optimal pick-up area, are less sensitive to cardioid, supercardioid, and shotgun polar pattern microphones. Background noise can be decreased by using this quality. Position microphones so that the noise sources are in the null, or least sensitive area, of the polar pattern when noise sources cannot be eliminated. The polar pattern determines the precise null angle. The null angle shifts as microphones become more directional; a cardioid microphone’s null is 180 degrees off-axis. A supercardioid microphone’s null is located between 127 and 233 degrees.
Use a Low-Cut Filter at the Microphone or First Stage of Amplification
Most ambient noise has a “pink noise” quality to it, with more energy at low frequencies and less at higher ones. When recording dialog, it’s best to use a high-pass (also known as low-cut) filter because voice energy is very low below 100 Hz. A significantly more aggressive high-pass of up to 320 Hz can be utilized for applications where speech intelligibility is more critical than preserving a genuine, full-sounding voice output. Keep in mind that “telephone-grade audio” has a frequency response of around 300 to 3,000 Hz and is optimized for 90% of spoken energy.
High-pass filters are built into many microphones. First, apply the filter to the microphone. If more high-pass is required, turn on the preamplifier’s version of it. The slope of the filter increases with the usage of high-pass filters on both the microphone and preamplifier, hastening the falloff of low frequencies.
Reduce the Number of Open Microphones
Sometime the term “open” is used to describe microphones that are currently recording. The overall background volume in the mix rises by 3 dB for every doubling of open mics. For instance, there is a 9 dB speech-to-noise penalty when all the microphones are open during the recording of a panel discussion with eight participants as opposed to when only one microphone is open.
It’s challenging to manually control a scene with numerous talkers, especially for unscripted material. Sound engineers can concentrate on the overall mix by using Sound Devices MixAssist and Dugan automatic mixing, which automatically opens and closes microphones.
Use Real-Time Noise Suppression
Although there are numerous computer-based choices for noise reduction, there aren’t many portable options for real-time noise suppression in the field. Sound professionals that required portable real-time noise suppression on-location frequently chose CEDAR’s stand-alone noise suppression equipment. With Sound Devices NoiseAssist, adaptive, real-time noise suppression is now immediately accessible in a mixer-recorder for the first time in the history of professional sound.
main causes of background noise and how to eliminate them
Speech and background noise are separated using a sophisticated algorithm by the real-time, single-ended noise reduction system known as NoiseAssist. With only one variable, the background noise attenuation level, NoiseAssist is simple to use. Although 3-6 dB of attenuation is enough in the majority of circumstances, up to 20 dB of suppression is available. Applications for real-time noise suppression systems like NoiseAssist include quick turnaround productions without post, live broadcast and streaming, previews on set, feeds to video villages, IFB feeds, rough guide mixes, and more.
Record the unprocessed channel when applying any form of noise suppression so that it can be sent to post-production. Having a “raw” track free of any noise suppression is crucial because post-production provides a vast toolkit for processing audio. The 8-Series mixer-recorders provide a powerful feature that is simple to set up: the ability to record both a processed and an unprocessed track.
1. Room Environment
When recording at home, the room environment can be a significant source of background noise. Ascertain that the recording space is silent. Always turn off appliances that can cause a low hum in the recording, such as the TV and fans and air conditioners. Draw the curtains and lock all the doors and windows. After a time, it may start to feel a little stuffy, therefore it’s best to complete a session for 15-20 minutes all at once.
2. The Computer Fan
Too close to a computer (or laptop), a sensitive microphone can pick up the sound of the hard drives, the power supply, and the computer fan. The answer is to position the microphone at least 6 feet away from the PC. Point the side of the microphone with the highest sensitivity away from the computer when using a directional microphone. Additionally, you can purchase quiet computer fans to reduce noise during recording. (You’ll be astonished at how many brands are available to them!)
3. Internal Noise from the Sound Card
Internal computer parts like the sound card may produce a lot of electrical noise, which can add a lot of background noise to your recording. Test with “no inputs” and keep recording for a while to determine whether your system is generating internal noise. If the static in your recording is present, internal noise is confirmed. The sound card can be protected. But changing the sound card is the best option. The internal noise decreases with improved sound cards. There are excellent USB soundcards available for as little as $200 that produce virtually no noise.
How to Screen Record without Background Noise Mac
Using the Screen Recorder on a Mac
The screen recording (or screen capture) function is nothing new, but Apple has been steadily introducing new software to its devices for years. On a Mac, utilizing one of their two recording choices, it is simple to record a screen. Simply using the screen capturing command is the first option.
Press Command + Shift + 5 on your keyboard to bring up the toolbar for screen recordings and issue this command. This toolbar offers the ability to record the entire screen, a portion of the screen, or even a selection of apps. Additionally, there is an options button that will let you to choose different windows and pick whether or not you want a delay before you begin recording.
Make sure to select “Built-in Microphone” under “Options” in the toolbar before starting a screen recording. Your screen recording won’t have any sound at all if this isn’t checked.
The QuickTime Media Player is the alternative method for recording your screen using Apple’s software. You can record your computer’s screen using the program that comes preinstalled. Because it provides a lot more possibilities than just pressing Command + Shift + 5, the media player is helpful.
One of these crucial options is the QuickTime Player’s ability to allow you select the sound input you want to use for your screen recordings. While it is difficult to record audio from other apps that are open on your device, it is simple to choose the microphone on your computer as your audio input device.
Any speech you make will be recorded on the screen if you use the internal microphone as your audio input option. After accomplishing this, you can edit the sound and video files to include the desired segments. This is the most straightforward method for recording what you want, how you want, but it also comes with the extra challenge of having to add undesired background noise.
Using Noise Suppression
Finding a means to eliminate background noise is necessary if you are recording something and simply want to hear your voice. Although it is not always possible, you can choose a peaceful area to record in. Fortunately, there are a few choices available for those who want to drown out background noise while maintaining their voice’s audibility.
To begin with, you can edit recordings to remove ambient noise. To do this, use QuickTime Player on your Mac and choose the recorded screen. Then, select a segment of the audio where the background noise should be eliminated. Finally, select Noise Removal from the “Effects” option and adjust the scale to your preference. The audio will reduce background noise further as you adjust the scale.
Most of your sound files should be able to be edited with this straightforward program to remove background noise. There are a few other solutions available to you, though. Use of a headset with a microphone is one of these. Typically, headset microphones include their own sort of noise cancellation to ensure that they only pick up your voice. They won’t perform flawlessly, but they will nonetheless perform admirably.
Alternative Screen Recordings
There are still a few alternate options that one might use to capture a screen recording while still being able to filter out and eliminate the background noise if they are having trouble dealing with screen recordings on Mac or if they do not want to utilize QuickTime Player. Using Zoom is among the simplest ways to accomplish this.
An program called Zoom enables simple video calls between users. It is frequently used in both business and education to provide cross-location communication between coworkers, teachers, and students. However, if a person wishes to take a screen recording without background noise, Zoom’s software can be simply modified to meet their demands.
Open Zoom and begin a new meeting to achieve this. Next, select the screen sharing button in the center of the bottom of the page. You can choose which windows to record or whether you just want to share the whole screen by doing this. You must access your audio settings by clicking a small button next to the mute button after you have configured the screen sharing to your liking.
There are a couple sliders that let you change the input sensitivity in the audio settings. Your microphone will pick up on small and quiet noises for your recording if the sensitivity is increased. You may tell your microphone to only pick up the loudest sound—your voice—by lowering the sensitivity.
By selecting the choices button and either starting a recording on your computer or on the cloud, you may start recording. Zoom will start to record your screen and audio as soon as you make your selection. Zoom has the wonderful feature of making it simple to mute your microphone by just pressing the mute button. Depending on what you plan to use the tape for, you can also include a video of yourself in the recording.

We wanted to include it on the list since we believe that most people will simply use it in the future. We don’t have a Google Play button since you don’t need an app. If you require additional assistance, you may read our instructional.
Other methods for screen recording
There are other ways to record your screen on Android and that is by using hardware. There are two main ways to do so using hardware:
- Professionals often use a capture card to hook their Android device right into their computer and record it from there. Capture cards can get rather expensive but you’ll get probably the best frame rates and quality. Plus it records directly to your computer hard drive which allows for much larger recordings. Earlier models had to work around some potential HDCP problems, but modern capture cards don’t have that problem.
- There are other apps like Vysor on the Google Chrome app store. The basic idea is to connect your phone to your computer. It then mirrors the screen directly to your computer. From there, you just have to figure out how to record it yourself. It’s not the easiest method by any stretch. Each app also has a different setup. However, it is an option.
- Some Chromebooks now include the ability to mirror your Android device directly to it. This, of course, requires buying a Chromebook. That’s an unreasonable expenditure for what should be a relatively simple task. However, we do try to cover all of the bases here and this is definitely an option. You still need an app to record your Chromecast screen, though.
Recording an audio recording without background noise can be a great way to get a clear and concise audio recording. In order to avoid any background noise, make sure that you have the appropriate equipment and record at a quiet volume. Additionally, take extra care when recording an audio recording with background noise, as it may not be possible to edit the sound or remove any unwanted noise. By following these simple steps, you can create a high-quality audio recording that will help you capture important business moments.
