to know.

Does my audio leave my computer?
OpenKrisp processes your audio locally on your device. It doesn’t upload audio to a cloud service for noise reduction. Your call app still handles the call itself.
Can I clean just one side of the call?
Yes. Your microphone and incoming call audio have independent controls. Use either one on its own, or turn on both.
Which call apps can I use it with?
Use a call app that lets you select its microphone and speaker devices. Choose OpenKrisp Microphone and OpenKrisp Speaker in its audio settings. Compatibility is still being tested during the beta.
Is it available for Windows or Intel Macs?
The current beta targets Apple Silicon Macs and x86-64 Linux. Windows and Intel Mac installers aren’t provided.
Can I use it for music or without headphones?
Noise reduction is designed for speech. Use your usual audio output for music. Start with headphones for calls; speakerphone use hasn’t been validated yet.
Is OpenKrisp fully open source?
Yes. The current OpenKrisp source is licensed under GNU GPLv3 (GPL-3.0-only). You can use, inspect, modify, and redistribute it, including commercially, under the license’s terms. Distributed covered modifications must preserve GPLv3 licensing and corresponding source access for recipients. Earlier beta installers retain their original bundled terms.
