Krisp alternatives for Windows: choose the right noise filter

How to use this comparison

KleenMic publishes this site, so we have a commercial interest in one of the options. This is a feature and fit comparison based on the vendors’ documentation, not an independent audio benchmark. Availability and app interfaces can change; check the linked sources before choosing.

Compare the options

Use the filter already in your calling app

If you spend most of your time in one service, test its own control before installing another app. Zoom’s Audio settings include background noise suppression levels. Teams offers a noise suppression toggle in device or meeting audio settings. Discord’s Voice & Video settings offer its Krisp integration; Discord says this filters noise from your side and is free within Discord.

These choices avoid an extra virtual input, but a setting in one app does not automatically configure another. On a managed computer, your organisation may control available settings. Compare a test call with suppression on and off, especially if your room is already quiet or you need to transmit music.

Choose KleenMic for a reusable microphone

KleenMic focuses on microphone noise removal. Select your physical microphone in KleenMic, then select KleenMic in each calling app (or the exact virtual microphone name shown by Windows, which may include an adapter suffix); keep your usual speakers or headphones as output. It runs on 64-bit Windows 10 and 11; Windows 11 on Arm uses x64 emulation. Its 72-hour trial lets you check your own microphone and room before purchase. The license is $20 once for one active computer, Mac or Windows.

The Windows installer is self-signed and can show an unknown-publisher or SmartScreen warning. The installation guide explains the warning and setup. Get it from the official download page. KleenMic does not offer meeting notes or transcription, and the Windows release does not provide speaker acoustic echo cancellation. If those are essential, assess another product or the calling app’s own features.

Consider NVIDIA Broadcast if your PC supports it

NVIDIA Broadcast offers microphone and speaker noise removal, room echo removal and camera effects. NVIDIA lists a GeForce RTX 2060, Quadro RTX 3000, TITAN RTX or higher and 8 GB RAM among its baseline requirements; some effects require a higher GPU. It also requires internet access during installation. Check NVIDIA’s current requirements for your architecture, driver and chosen effects before installing. NVIDIA says combining effects increases system impact.

Like other virtual-device tools, select its device in the calling app after configuring the physical microphone. It is a useful option when you already have compatible hardware and want additional effects, rather than a universal choice for every Windows PC.

When Krisp may be the better fit

Krisp’s standalone AI Meeting Assistant includes noise cancellation and offers meeting recording, transcription and notes. Its noise cancellation documentation describes microphone and speaker processing, voice isolation and echo cancellation; feature availability depends on the plan and conditions. That broader scope is relevant if you need to clean incoming sound or capture meeting information as well as filter your own microphone. Krisp says noise cancellation runs locally on your device. Recording, Note Taker and transcription have separate data handling: Krisp says transcription is processed in the cloud and meeting recordings are stored there. Review its current feature, plan and privacy information for your intended use.

Discord’s integrated Krisp filter is a separate in-app option. Do not assume it includes all features of the standalone meeting assistant.

Make a practical choice

1. Test the built-in filter if your problem is limited to Zoom, Teams or Discord.
2. For several apps, decide whether a virtual microphone is worth configuring in each one. Try KleenMic if its microphone-focused feature set fits.
3. If you have compatible RTX hardware and want video or speaker effects, check NVIDIA Broadcast’s requirements.
4. If notes, transcription or incoming-audio processing matter, compare Krisp’s current feature and plan details.

Use the same room, microphone position and representative background noise for each test. Avoid stacking filters initially, and listen for clipped words as well as remaining noise. There is no reliable universal winner without testing the setup you actually use.
