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.

Details about 3 modes

Auto Best NC Low Power Usage

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.


CPU overload warning

Versions below 2.0.0 Versions 2.0.0 and above
Mac Windows

No matter the selected option, if your system performance is not enough to process audio well at some point, Krisp informs you about that through warnings from the Krisp app icon and in the app itself: “Krisp detected a high system load that may impact your voice quality”.
The noise cancellation does not stop from being applied to your audio, but the voice might become robotic or get clipped.

Once your computer performance stabilizes the warnings will be gone.
