If you spend any part of your day on video calls, you have probably wrestled with background noise. Dogs barking, construction outside, a coffee shop that seemed quiet until you unmuted. AI noise cancellation tools promise to strip all of that out in real time, leaving only your voice for the other participants. Krisp and NVIDIA RTX Voice (now part of NVIDIA Broadcast) are two of the most talked-about options, but they take fundamentally different approaches to solving the same problem.
Krisp is a standalone software product that works on any computer, regardless of which processor or graphics card it has. NVIDIA RTX Voice started as a dedicated noise-removal utility and has since been folded into the broader NVIDIA Broadcast application, which bundles noise cancellation with camera effects like background blur and auto-framing. The catch is that NVIDIA Broadcast only runs if you have an NVIDIA RTX graphics card.
That hardware requirement is the single biggest factor separating these two tools, and it shapes everything from who can use them to how they perform.
This comparison breaks down the differences so you can decide which one fits your setup and your workflow.
Krisp
How it works
Krisp is built as a virtual audio device that sits between your microphone and whatever communication app you are using. Once installed, you select Krisp as your microphone and speaker in Zoom, Google Meet, Microsoft Teams, Slack, or any other calling platform. The noise cancellation runs entirely in software, processing audio through Krisp's AI models on your CPU. No special hardware is required.
Beyond noise cancellation
The product has grown well beyond basic noise removal. Krisp now offers echo cancellation, background voice removal (filtering out other people talking near you while keeping your voice), and meeting productivity features like AI-powered transcription, meeting notes, and summaries. It positions itself as a meeting assistant as much as a noise cancellation tool.
Platform support
Krisp works on both Windows and macOS, which gives it a reach that hardware-dependent solutions cannot match. It runs on Intel and AMD processors, on laptops with integrated graphics, and on Apple Silicon Macs. If your machine can run a video call, it can run Krisp.
Pricing
Pricing follows a freemium model. The free tier gives you 60 minutes of noise cancellation per day with the same audio quality as the paid plans, though unused minutes do not roll over. The Pro plan costs around $8 per month when billed annually (roughly $12 month-to-month) and removes the time cap, adding unlimited noise cancellation along with expanded transcription, meeting notes, and full background voice removal. A Business tier adds team management features, an admin console, and centralized billing. Enterprise pricing is negotiated individually and includes compliance documentation, dedicated support, and SDK access for call-center deployments.
The 60-minute daily cap on the free plan is generous enough for light use but will feel restrictive if you have back-to-back calls. For anyone who spends more than an hour a day in meetings, the Pro plan is the practical starting point.
NVIDIA RTX Voice and NVIDIA Broadcast
From RTX Voice to Broadcast
NVIDIA RTX Voice launched in 2020 as a standalone noise cancellation tool that used the tensor cores in NVIDIA's RTX graphics cards to filter background noise from both incoming and outgoing audio. It was free, effective, and quickly became popular among gamers and remote workers who already had compatible hardware.
In 2021, NVIDIA folded RTX Voice into NVIDIA Broadcast, a more ambitious application that combines noise cancellation with video effects. Broadcast adds AI-powered background removal and replacement, auto-framing that keeps you centered in the frame as you move, and eye contact correction. The noise cancellation engine is the same one that powered RTX Voice, but now it lives alongside a suite of camera tools.
Hardware requirements
The hardware requirement is strict, though. You need an NVIDIA GeForce RTX 2060, Quadro RTX 3000, or Titan RTX at minimum, along with at least 8 GB of RAM and Windows 10 or later. macOS is not supported. If you are on a laptop with Intel integrated graphics, an AMD GPU, or an older NVIDIA GTX card, Broadcast will not run. The application also requires up-to-date NVIDIA drivers.
Performance and quality
Because the audio processing runs on the GPU's tensor cores rather than the CPU, Broadcast imposes very little load on your processor. This is a meaningful advantage if you are already running resource-heavy applications alongside your calls. Gamers who stream, for example, can run noise cancellation without sacrificing frame rates. The GPU handles the AI inference separately from whatever else the CPU is doing.
The noise cancellation quality in Broadcast is strong, particularly for steady-state noise like fans, air conditioning, and keyboard clatter. It handles transient sounds like dogs barking or doors slamming reasonably well, though very loud or sudden sounds can occasionally bleed through. The processing is done locally with no audio sent to NVIDIA's servers.
Pricing
NVIDIA Broadcast is free to download and use. There are no subscription fees, no time limits, and no premium tiers. If you have compatible hardware, you get everything.

How to choose
The decision comes down to two questions: what hardware do you have, and what do you need beyond noise cancellation?
If you are on a Mac, the choice is made for you. NVIDIA Broadcast does not run on macOS, so Krisp is your option. The same applies if you are on a Windows machine with an AMD GPU or an older NVIDIA card that predates the RTX line.
If you have an NVIDIA RTX GPU and you only need noise cancellation, Broadcast is hard to beat. It is free with no usage limits, offloads processing to dedicated hardware so your CPU stays unburdened, and bundles useful video features like background blur and auto-framing at no extra cost. For gamers and streamers who already have RTX cards, it is the obvious pick.
If you need meeting productivity features, Krisp makes more sense. Transcription, AI meeting notes, and background voice removal go beyond what Broadcast offers on the audio side. If you work in an open office or a shared space where other people's conversations bleed into your microphone, Krisp's background voice removal is a feature that Broadcast simply does not have.
If you are deploying for a team, Krisp's Business and Enterprise plans offer centralized management that NVIDIA Broadcast lacks entirely. IT departments that need to deploy noise cancellation across an organization, enforce policies, and manage billing from a single dashboard will find that Krisp is built for that use case while Broadcast is a consumer tool.
If cost is the priority, individuals with RTX hardware who just want clean audio should start with Broadcast. Anyone who needs cross-platform support, meeting intelligence, or team administration should look at Krisp.

Frequently asked questions
Is NVIDIA RTX Voice the same as NVIDIA Broadcast?
RTX Voice was a standalone noise cancellation tool that NVIDIA released in 2020. In 2021, NVIDIA incorporated its functionality into the broader NVIDIA Broadcast application, which adds video effects alongside the original audio noise removal. RTX Voice as a separate download is no longer actively maintained. If you install NVIDIA Broadcast, you get everything RTX Voice offered plus the newer camera features.
Can I use NVIDIA Broadcast without an RTX GPU?
No. NVIDIA Broadcast requires a GeForce RTX 2060, Quadro RTX 3000, or Titan RTX at minimum. The noise cancellation and video effects rely on the tensor cores found in RTX-series GPUs. Older GTX cards, AMD GPUs, and Intel integrated graphics are not supported.
Does Krisp work on Mac?
Yes. Krisp runs on both Windows and macOS, including Apple Silicon Macs. This is one of its key advantages over NVIDIA Broadcast, which is Windows-only.
Is Krisp free?
Krisp offers a free tier that provides 60 minutes of noise cancellation per day. The noise cancellation quality on the free plan is the same as on paid plans. Once you hit the daily cap, filtering stops until the next day. The Pro plan at roughly $8 per month (billed annually) removes the time limit and adds transcription, meeting notes, and other features.
Does NVIDIA Broadcast send my audio to the cloud?
No. All processing in NVIDIA Broadcast happens locally on your GPU. No audio or video data is transmitted to NVIDIA's servers. The same is true of Krisp, which processes audio locally on your CPU.
Which one has better noise cancellation quality?
Both tools handle common background noises like fans, typing, and ambient chatter well. NVIDIA Broadcast can have a slight edge with steady-state noise because it runs on dedicated AI hardware, while Krisp performs strongly across a wider range of transient sounds. In practice, most users would find the quality comparable for typical meeting scenarios. The differences become more apparent in extreme noise environments.
Can I use Krisp and NVIDIA Broadcast at the same time?
Technically you could chain them (running your microphone through one and then the other), but this is not recommended. Running two noise cancellation layers can cause audio artifacts, reduce voice quality, and introduce latency. Pick one and use it on its own.
Does NVIDIA Broadcast work with Zoom, Teams, and Google Meet?
Yes. Like Krisp, NVIDIA Broadcast registers as a virtual audio and video device on your system. You select it as your microphone, speaker, or camera in whatever communication application you use. It is platform-agnostic in that sense and works with Zoom, Microsoft Teams, Google Meet, Discord, Slack, and others.
What happens if I exceed the 60-minute daily limit on Krisp's free plan?
When you reach the daily cap, Krisp stops filtering noise. Your audio continues to pass through normally (unfiltered), so your call does not drop. The limit resets the following day. Unused minutes from one day do not carry over to the next.
Does Krisp offer anything for teams or businesses?
Yes. Krisp has Business and Enterprise plans that include an admin console, team dashboards, centralized billing, and policy enforcement. The Enterprise tier adds SSO, compliance documentation, dedicated support, and SDK access for integrating noise cancellation into call-center infrastructure. NVIDIA Broadcast has no team or enterprise features.
Will NVIDIA Broadcast slow down my games or other GPU-heavy applications?
The impact is minimal for most users. Broadcast uses a small portion of the GPU's tensor cores, which are separate from the CUDA cores that handle game rendering. On mid-range and higher RTX cards, the performance hit is negligible. On lower-end RTX cards running demanding games at high settings, you might see a small frame rate reduction, but it is typically in the range of a few percent.
Can Krisp remove background voices, not just background noise?
Yes. Krisp's background voice removal feature filters out other human voices picked up by your microphone while preserving your own. This is useful in shared workspaces, coworking spaces, or at home when other people are talking nearby. This feature is available on paid plans.
