Best practices for Krisp AI Noise Cancellation

Krisp AI Noise Cancellation works best when your devices are configured correctly, and your system can handle real-time processing. Use the tips below to get the best results during live calls.

1. Prepare everything in advance

   • Admins: Confirm that the team configuration is correct and optimized for your team's use case.
   • Users: Set everything up in your calling application and test Noise Cancellation before joining a call.

2. Position your headset correctly

   • Follow our headset positioning tips for the best results.
     

3. Speak clearly and at a natural pace

   • Krisp Noise Cancellation distinguishes your voice from background sounds. Clear, steady speech makes it easier for Krisp to capture your voice accurately.
   • Avoid speaking too quickly or too softly, as this can make your voice harder to separate from background noise.

4. Ensure your microphone audio is not overprocessed

   Info

   Krisp Noise Cancellation works well with most built-in OS audio enhancements. However, combining these with other audio enhancement layers can reduce output quality. If you notice issues, try disabling them.

   Multiple layers of processing can distort your voice before Krisp receives it. While Krisp works with most built-in noise-cancelling features in modern headsets and softphones, aggressive processing in the original audio can result in quality degradation.

   • Turn off headset enhancements when possible (built-in microphone noise cancellation, voice effects, or equalizers).
   • Disable additional audio processing in your softphone, browser, or OS (for example, extra noise suppression or enhancement modes).

5. Check your volume levels

   • If you're inaudible to the caller, your microphone volume may be too low. Check the volume level for both your headset and Krisp.
   • If your volume changes automatically, a volume normalization/automatic gain control feature might be at play. For best results, ensure your microphone level is high enough and use the Lock at optimal level setting for Krisp Microphone volume.
     

6. Make sure your device meets the minimum requirements

     Important

   If your device doesn't meet the minimum requirements, you may not always see high CPU usage, but audio quality can still diminish. Older CPUs can have real-time processing limitations that affect Noise Cancellation performance.

   Noise Cancellation runs in real time and is sensitive to processing limitations.

   • Confirm your machine meets the minimum system requirements.
   • Close CPU-heavy apps and processes during calls when possible (video rendering, large downloads, many active browser tabs).
