The Noise Cancellation, with its 3 modes, allows you to adjust the usage of the app based on your needs. That is, whether you give more importance to having the best noise cancellation experience, the highest possible voice quality, or keeping the CPU usage balanced.
Selecting the Noise Cancellation mode
To select the desired mode for the upcoming calls:
- Go to Krisp Preferences >>> Audio.
- Click on the Noise Cancellation mode list.
- Select the mode.
The modes can also be changed directly during the call.

- See the Voice Preferences automatically open up.

Noise Cancellation modes and Background Voice Cancellation on Mac
If Background Voice Cancellation is enabled, the Noise Cancellation mode will automatically be set to "Default". It provides noise and voice cancellation and cannot be changed.
You cannot have HD voice quality or intentionally use less CPU while you are in the "Default" mode.
To be able to change the Noise Cancellation mode, disable Background Voice Cancellation as shown here.
What is this?
This mode automatically gives you the best noise cancellation, voice quality, and balanced CPU/RAM usage whenever possible. The settings are adjusted accordingly based on the quality of your microphone and the current computer load. The accent here is on the noise cancellation though. In case there is a high usage of your CPU/RAM at some point, you might have a small decrease in the voice quality, but the app will always try to keep the noise cancellation on top.
When to use?
Select this mode if you use Krisp for communication purposes.
What is this?
This mode may consume more CPU/RAM resources but always tries to keep the audio quality at the highest level. Sometimes that can happen at the expense of the noise cancellation accuracy which might go from perfect to good to be able to process your voice at HD quality.
When to use?
Select this mode when the high-quality voice is important for you. Common use cases are recordings, streaming, or podcasting.
Hint
To benefit from this mode, make sure to use a microphone that is able to stream HD audio. For that, the device should be able to support a 32KHz or higher sampling rate.Info
If your audio setup (microphone, or audio connection) does not support HD audio, Krisp will not be able to process your voice in HD. When the received audio is originally not of good enough quality, Krisp does not recover or improve it.What is this?
With this mode, Krisp handles the noise cancellation in a decent way while using considerably less CPU/RAM. There might be some difference in the noise cancellation quality, but it shouldn't be very noticeable. Here as well, if your microphone is able to stream in HD, your audio will be of high quality.
When to use?
Select this mode if your computer is usually overloaded and does not have much free CPU/RAM capacity. A common use case is gaming, simultaneous active usage of heavy software when your machine itself is not powerful enough or you simply do not want Krisp to consume too much CPU/RAM.
Info
The HD icon can be present in your Krisp app in case your microphone is able to transmit your voice in HD quality. If it’s not, you will see only the blue leaf icon.
To select the desired mode for the upcoming calls:
- Go to the Preferences >>> Audio.
- Click on the Noise Cancellation mode dropdown list.
- Select the mode.

CPU overload warning
No matter the selected option, if your system performance is not enough to process audio well at some point, Krisp warns you about that through the Krisp app or system notification.
If you are on Best Noise Cancellation mode, you can switch to Auto mode so the load will be successfully optimized.
Once your computer's performance stabilizes, the warnings will be gone.
