to know.

Does OpenKrisp upload my audio?
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 reduce noise on just one side of the call?
Yes. Noise reduction has separate controls for your microphone audio and the audio you hear. Turn it on for either or both.
Which call apps can I use it with?
Use a call app that lets you choose your microphone and speakers. Select 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. OpenKrisp’s source and current beta downloads use 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. Releases before beta 4 retain their original bundled terms.
