Last checked:
Getting started
- Check current Windows or macOS requirements, create an account and install the desktop application.
- In Krisp, select your physical microphone and speaker, then enable the required noise cancellation toggles.
- In the calling application, choose Krisp Microphone and Krisp Speaker for the corresponding audio paths.
- Make a short trial call; compare speech with processing on and off, including quiet words and interruptions.
Decision points
- If others hear your room noise, prioritise microphone processing; if their surroundings distract you, consider speaker processing.
- If voices sound unnatural, inspect overlapping noise suppression and echo processing; Krisp recommends avoiding duplicate processing in the calling app.
Limits
- This listed workflow handles live calls. Do not select it on the assumption that it cleans an uploaded audio file.
- The documented desktop app supports Windows and macOS; Linux and Chrome OS are not supported.
- Krisp’s virtual devices are mono, so this workflow is unsuitable when preserving a stereo music mix is essential.
Frequently asked questions
Why does installing Krisp not change my call?
The call may still use the physical microphone directly. Check device selection in both Krisp and the calling application.
Is the free allowance enough for daily meetings?
No allowance was verified for this guide. Check your account’s current plan before relying on it for a full working day.
