Written By FarhanMax

Are you wondering about Discord’s noise suppression feature Krisp, how it works, and the benefits? 

Then you landed on the right page! 

As a regular Discord user for the past two years, I can provide all the information you need to know about Krisp.

What is Discord’s Krisp?

Krisp is an AI noise suppression tool featured in Discord. Krisp noise suppression is a more advanced version of Discord’s noise reduction feature. It uses machine learning methods to filter out background noise, except the user’s voice. Krisp relies on the CPU to run the suppressing algorithm.

How Does Krisp Work? 

As I said before, Krisp uses machine learning to filter out all the background noises that can interrupt a friendly conversation, but technically, it’s more complex.

Krisp creates an additional layer between the physical microphone/speaker and the communicating app you are using.

The audio is received from your physical microphone, processed on your device to remove noise by Krisp Microphone, and then transmitted to the communication app to remove the noise going from you to other participants.

The noise cancellation for the voice going to your microphone and coming from your speakers is made directly on your device, and the audio data is not stored anywhere or sent to any servers.

Many people face the problem of “Discord Notification not working“. You can fix it easily by following a few steps on our separate guide.

How to Get Krisp?

Krisp noise suppression feature is now a built-in feature of the Discord app. However, it isn’t turned on from the beginning. You have to turn it on manually, and then you’re good to go.

You’ll need to adjust some additional options inside Discord settings to make Krisp more effective.

Why is Krisp Not Working in Discord? 

If Krisp is malfunctioning, check if it’s enabled in Discord first. If Krisp isn’t functional, several issues like conflicting Discord voice settings, input sensitivity, and conflicting background processes might be causing the malfunction. Fixing these issues will bring Krisp back on track.

If your Discord’s Krisp noise-suppressing feature isn’t working, there might be some issues causing you this inconvenience. I’ve listed and explained them below for your better understanding.

Here are the reasons that might cause Discord’s Krisp malfunction:

Krisp is Disabled in Discord

If Krisp isn’t working on your device, the most common issue is that it’s not enabled on your Discord.

You can swear that you’ve enabled it from the settings on a previous session but, it is not working now. Well, Krisp requires a fair amount of CPU and RAM usage to run it’s machine learning algorithm to filter out the background noises. But, sometimes, due to accommodating other mandatory background processes, your CPU ends secondary processes like Krisp.

If this is the case, then Krisp will not work on your device on Discord as it is supposed to do.

Enabling Alternative Noise Reduction Service

Enabling another noise reduction service along with Krisp to reduce background noises from Discord voice and video chats will result in Krisp’s malfunctioning.

Krisp is Discord’s built-in noise suppressing service that suppresses noises from participants’ surrounding environment to deliver a crispy user experience. But, Discord also has other noise reduction services, and you can turn them on from Discord’s settings.

But, enabling both Krisp and Discord’s alternate noise reduction service can conflict with each other and disable Krisp.

CPU and RAM Shortage 

Sometimes Krisp noise suppression service can malfunction in the Discord app due to your device’s CPU usage and RAM shortage.

Discord’s Krisp service requires a fair amount of CPU and RAM usage to keep itself running as it does all the noise suppression in real-time running a machine-learning algorithm with the help of your device’s CPU.

When the other apps installed on your device occupy most of the RAM and CPU usage, Krisp is forced to end its process due to CPU and RAM shortage.

Conflicting Background Processes of Discord

Every app needs to run background processes to perform smoothly and provide a seamless user experience. But, sometimes Discord fails to launch a process or two at the startup, and Krisp might be one of them.

Discord launches a bunch of background processes and keeps them running to keep it’s additional features on hand, ready for your usage. But if it fails to run any of the crucial background processes, you’ll experience a hard time using those features.

If you’re unlucky, the Krisp noise suppression service might be one of those failed to launch processes.

This step also helps in fixing discord Krisp not working issue.

Enabling Automatic Input Sensitivity

The automatic input sensitivity option of Discord sets the sound level above which the mic should pick up your voice automatically. If you set an input sensitivity level, discord will always pick up your voice over a certain loudness level.

The automatic input sensitivity service can sometimes malfunction as it’s a complicated process. If you’ve enabled this option in Discord’s settings, Krisp might have difficulty processing the voice input and malfunction.

How to Fix Krisp Not Working in Discord?

What are the Differences Between Krisp and Noise Reduction? 

Discord’s noise reduction feature reduces noise from the input signals by generating a low wave frequency to eliminate noise with a high wave frequency. On the other hand, the Krisp noise suppression feature offers a machine learning algorithm that filters the noise wave.

There’s a remarkable difference between the all-new Krisp and the generic noise reduction feature of Discord.

The noise reduction feature in Discord primarily focused on reducing environmental noises from the input signals by generating a low wave frequency to reduce noise with a high wave frequency. 

This process comes with a delay and is now considered old-fashioned.

On the other hand, the noise suppression feature introduced by Krisp offers a machine learning algorithm that filters the noise wave. It does the trick by running it through the algorithm and filtering out unnecessary noises from the surroundings.

Noise suppression of Krisp is relatively faster than the noise reduction feature cause the whole suppression process is done locally in your device’s COU and saves time than generating an anti-wave.

So, you can safely say that the Krisp noise suppression feature is superior to the noise reduction feature of Discord.
