Are there any noise-cancelling applications that can produce counter-noise through a laptop’s integrated microphone?

How to Reduce Microphone Background Noise on a PC

What is Krisp | Noise Cancelling App?

Krisp is a noise cancellation app that uses artificial intelligence to clean up the audio. It works in real-time, creating what is effectively a protective layer between the microphone and the application you are using to ensure that background noise is filtered out.

Not only does it filter out background noise from the microphone, but it can also filter out background noise from other people during your call, so the audio you hear is cleaner too.

Because it is software-based, it is a simple solution and does not require any special hardware; It will work with the built-in microphone on the laptop, the microphone on the webcam, or an external microphone. It will also work with common applications such as Zoom, Teams, Skype, Meet to make sure your video conference audio is nice and clear.

All processing is done locally on your device, which means you are not sending audio to the cloud so it is private too. What platforms does Krisp work on? There are several versions of Krisp, there is the desktop application available for macOS or Windows. They are ideal for typical home or office situations, where you must want cleaner audio for services like Zoom.

Then there is the Chrome extension, which will work within the Chrome browser if installed and allow you to cancel noise when using web apps within Chrome or when using ChromeOS. It could be on Meet, the web app version of Zoom, or something like the Zencaster recording.

There is also a Krisp dialer for iOS. This is designed to make your iPhone audio cleaner when connecting to meetings. For those who need to attend a conference call when they are not at their desk, this is designed for you.

How to get started with Krisp

When you install the Krisp app for the first time, you will be guided through the steps you need to take to get it working. We’ve installed it on both Windows and Mac, the latter of which seems to run a bit smoother when it comes to changing audio inputs.

The important thing to understand about the Krisp app is that it is like having another microphone to choose from. When using an application like Zoom or Teams, you must make sure you have “Krisp” selected as the audio input.

For example, let’s see how to configure Krisp with Zoom.

Download the Krisp app and follow the installation instructions given below:

Open Zoom and go to Settings.

Open the audio settings and then from the drop-down box select Krisp for your microphone and Krisp for your speaker.

In the Krisp application, select the microphone you want to use and the speakers you want to use. Basically what you are doing is telling the app to use the Krisp and telling Krisp what hardware to use.

The installation process is basically similar to other applications. On Google Meet, for example, you can select the Krisp app in the settings as soon as you open meet. Google. In Skype, go to the audio and video settings in the app and do the same.

In Slack, you must change these settings once you start a call; just remember to select the Krisp microphone and speaker as an option when you open an app.

Does Krisp really work?

Yes, it is surprisingly effective. Below is an example of a typical Zoom conference call — reading British Prime Minister Boris Johnson’s coronavirus speeches from May 10, 2020, against a virtual backdrop of Downing Street, while tapping a piece of wood with an ax.

Results are typical of what you will experience with Krisp. There is audio clipping when there is a loud noise to cancel, leading to a slightly artificial vocal sound, but this is an extreme case in our test. Unless you are calling from a construction site, you are unlikely to need such strong noise cancellation.

Importantly, things like door locks, traffic noise, airplanes, birds, children walking up and downstairs, and other things that you normally hear on conference calls are gone — and we tested it with all kinds of sounds and we found that generally unless it’s a very loud or sudden noise, it doesn’t disturb the audio.

But we have noticed that this increases the demands on your PC. We tested it primarily with a MacBook Pro and found that even in short video calls, fans will turn on the Mac as the demands are obviously higher than for a standard video call. Fortunately, the sounds of the fans are also filtered.

How much does Krisp | Noise Cancelling App cost?

There is a free tier for Krisp that will give you 120 minutes (2 hours) free per week. It will cost nothing.

The Pro tier costs $ 5 per month (if you choose to pay monthly) and this gives you unlimited time plus you can use Krisp on three devices. There is also a Teams tier that costs $ 5 per user per month that will provide centralized billing and management for those who want Krisp for a larger workforce.
