There is no independently proven, universal sound-quality winner. Start with NVIDIA Broadcast if you use Windows, already have a qualifying GeForce RTX or professional RTX card, and mainly need free outgoing-microphone cleanup for streaming. Start with Krisp if you use a Mac, do not have an RTX GPU, need the other person’s audio cleaned as well as your own microphone, or want one virtual microphone that can feed calls, Discord, OBS, and recording software.
Perceived quality depends on your microphone, keyboard and fan noise, room reflections, suppression strength, and the listener’s app. The most trustworthy answer for your setup comes from a short recording and A/B call test, not from a headline percentage. Krisp has published an older vendor test claiming a 10% average advantage over RTX Voice; that is Krisp’s own comparison of an earlier NVIDIA product, not an independent, current Broadcast-versus-Krisp listening test.
Quick verdict: choose by setup before chasing a sound-quality winner
| Question | Better starting point | Why |
|---|---|---|
| You stream on Windows and already own a compatible RTX card | NVIDIA Broadcast | It is designed for Windows RTX hardware, uses Tensor Cores for AI calculations, and presents free microphone cleanup as its core use case. |
| You use macOS or Windows without a dedicated GPU | Krisp | Krisp runs on Windows and Mac without requiring an RTX card. |
| You need to suppress noise in both directions of a meeting | Krisp | Its current product comparison describes cleanup for your microphone and incoming audio. |
| You need a virtual microphone for Discord, OBS, and recording apps | Krisp | Its streamer workflow routes processed audio through a virtual microphone that applications can select. |
| You want room-echo and microphone-noise controls while streaming | NVIDIA Broadcast | Its Noise Removal and Room Echo Removal features target keyboard noise, static, PC fans, and reverberant rooms. |
| You want meeting notes in the same product | Krisp | Krisp’s comparison lists AI meeting notes alongside noise cancellation. |
This table is a starting decision, not a laboratory ranking. If both products work on your computer, test them with the same microphone, noise source, and application before deciding which one sounds more natural.
What each application actually processes
NVIDIA Broadcast: an RTX-accelerated Windows effects app
NVIDIA describes Broadcast as an AI-enhanced application for livestreams, voice chats, and video-conference calls. Its relevant audio effects are Noise Removal and Room Echo Removal. They are intended to reduce sounds such as keyboard strikes, microphone static, PC fans, and room reverb before the signal reaches a call or stream.
#1 Best Overall
- AI Performance: 767 AI TOPS
- OC mode: 2632 MHz (OC mode)/ 2602 MHz (Default mode)
- Powered by the NVIDIA Blackwell architecture and DLSS 4
- Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure
- A 2.5-slot design maximizes compatibility and cooling efficiency for superior performance in small chassis
The important boundary is direction: the product is primarily positioned as outgoing microphone cleanup. It helps the other person hear a cleaner version of your voice; it is not the broadest choice when your priority is removing noise from the audio coming back from other participants.
Broadcast performs its AI calculations with Tensor Cores on supported NVIDIA hardware. That can make it an efficient fit for an RTX-equipped gaming or streaming PC, but it also creates a hard compatibility requirement. Buying or upgrading a GPU solely for noise suppression can cost substantially more than paying for a software plan, so include hardware cost in the comparison.
Krisp: cross-platform, system-level voice processing
Krisp’s current comparison describes the app as working on Windows and Mac without a dedicated GPU. It can process your microphone and incoming audio, which makes it useful for meetings where the room is noisy on either side of the conversation.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
For streamers, Krisp documents a system-level route: it removes keyboard and fan noise, exposes a virtual microphone, and lets Discord, OBS, or a recording tool receive the cleaned signal as an input. That routing is useful when an application has no built-in noise filter or when you want one processing choice shared across several applications.
Krisp also lists AI meeting notes as a meeting feature. That does not make the suppression algorithm inherently better, but it can change the value calculation for someone who wants transcription or notes in addition to cleaner calls.
Does one sound better? What the evidence can and cannot establish
No current independent apples-to-apples score
No independent current listening statistic establishes that Broadcast always beats Krisp, or that Krisp always beats Broadcast. A percentage from one product’s marketing material cannot settle a perceptual question that varies with microphone frequency response, distance from the capsule, noise type, room acoustics, and suppression settings.

How to interpret Krisp’s “10% better” statement
An older Krisp article says, “We conducted a full technical comparison of the noise reduction quality of the two apps, according to which Krisp’s technology showed a 10% better result on average.” The comparison was against RTX Voice, an earlier NVIDIA product, and the claim came from Krisp. It is not an independent benchmark of the current NVIDIA Broadcast application, and “10%” does not specify a universal listener-rated improvement that transfers to every microphone or noise environment.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesWhy your result can reverse from a published claim
- Noise spectrum: A steady fan, sharp keyboard transients, speech in the room, and broadband hiss challenge a suppressor differently.
- Voice and microphone: A close dynamic microphone may need less aggressive processing than a distant laptop microphone. A filter that rescues one mic can make another sound thin.
- Room reflections: Echo removal can improve intelligibility in a hard room, but strong processing may introduce a hollow or phasey character.
- Suppression strength: More reduction is not automatically more natural. Excessive settings can clip consonants, pump during pauses, or create robotic artifacts.
- Application path: A call app may add its own automatic gain control, echo cancellation, or noise suppression after the virtual microphone, changing what the listener hears.

NVIDIA Broadcast requirements and setup
Check the hardware before installing
NVIDIA’s FAQ lists these requirements for Broadcast:
- GeForce RTX 2060, Quadro RTX 3000, TITAN RTX, RTX Spark, or a higher qualifying model.
- At least 8 GB of system RAM.
- Windows 10 64-bit.
- Compatible NVIDIA drivers.
Check the exact model and current driver support before treating an RTX purchase as guaranteed compatibility. A non-RTX GeForce card does not meet the stated requirement, and Broadcast is not presented as a Mac application.
Configure a clean microphone for a call or stream
- Install and open Broadcast on the supported Windows system, then confirm that the application detects your physical microphone.
- Open the microphone section and select your real microphone as the source.
- Enable Noise Removal. Begin with a moderate setting so that speech remains natural; increase it only if the keyboard, fan, or static is still obvious.
- Enable Room Echo Removal when reflected room sound is the problem. Listen for a hollow or processed tone while speaking at normal volume.
- Select the Broadcast microphone in the destination app. In your call or streaming software, choose the Broadcast-processed microphone rather than the raw hardware input.
- Monitor the result. Use headphones and a local recording or test call. Confirm that the destination app has not added a second aggressive suppressor.
Do not select the raw microphone in one application and the processed device in another by accident. That creates inconsistent results and can make you think the effect is failing when the app is simply bypassing it.
Streaming-specific checks
- Make a short local recording in the same OBS scene and audio chain you use live.
- Speak while typing, moving the mouse, and allowing the normal PC fan load to occur; a quiet desk test cannot reveal keyboard or fan artifacts.
- Watch GPU and game performance after enabling processing. Broadcast is designed to use Tensor Cores, but your particular game, resolution, encoder, and GPU load still determine available headroom.
- Keep a raw microphone source available as a fallback scene or device. If an update or driver change breaks the virtual path, you can switch inputs without going silent.
Krisp requirements, pricing, and setup
Platform and plan facts
Krisp’s current pricing page lists a seven-day free trial. It lists Core at $16 per month or $8 per month when billed annually, and Advanced at $30 per month or $15 per month when billed annually. Both listed plans include unlimited noise cancellation. These are the prices shown at the time of the supplied information, October 20, 2026; verify the checkout total, currency, taxes, and regional availability before subscribing.
Rank #3
- Powered by the NVIDIA Blackwell architecture and DLSS 4
- Powered by GeForce RTX 5070 Ti
- Integrated with 16GB GDDR7 256bit memory interface
- PCIe 5.0
- WINDFORCE cooling system
Because Krisp does not require a dedicated GPU, compare its recurring cost with the price of the RTX hardware you would otherwise need for Broadcast. If you already own a qualifying card, that hardware cost is sunk; if you do not, “free” Broadcast is not a zero-cost route.
Route Krisp into calls and OBS
- Install Krisp for your operating system and allow it to access the microphone and audio devices requested by the operating system.
- Choose your physical microphone in Krisp and turn on noise cancellation for the microphone path.
- For incoming cleanup, enable the speaker or incoming-audio processing option when available in your Krisp interface, then choose the appropriate output device for your headphones or speakers.
- Open Discord, your meeting app, or OBS. In its audio input selector, choose the Krisp virtual microphone rather than the unprocessed physical microphone.
- In OBS, add or edit the audio input source and select the Krisp virtual microphone. Keep only one active processed microphone source to avoid doubling or feedback.
- Record a test clip and monitor with headphones. Check that the listener hears your voice clearly and that the incoming path is not being processed twice by the meeting application.
Krisp’s documented streamer workflow is valuable because the virtual microphone is an application-level handoff: the same cleaned signal can be selected by Discord, OBS, and recording tools. The exact device names can differ by operating-system version and installation state.
Run a fair A/B test with your own voice and noise
A controlled personal test is more useful than trying to infer a universal winner from marketing language. Keep every variable except the suppressor constant.
- Choose one sentence of 15 to 20 seconds. Include sibilants and plosives, such as “Six sharp sounds should stay clear while the keyboard is active.” Use the same distance, input gain, sample rate, and room position for every take.
- Record a raw reference. Capture the sentence with the normal keyboard, fan, or other noise that bothers you. Do not change the microphone position after this take.
- Record the Broadcast pass, if compatible. Use the same application, output level, and noise conditions. Note whether Noise Removal and Room Echo Removal are on and at what strength.
- Record the Krisp pass. Use the same source microphone and the same application path. If you are testing incoming cleanup, have a second participant play a repeatable noisy clip or speak from the same environment.
- Level-match the recordings. A louder clip often sounds “better” in a quick comparison. Adjust playback levels so speech peaks are comparable before judging tone.
- Listen for four outcomes: speech clarity, consonant detail, pumping during pauses, and robotic, watery, hollow, or metallic artifacts.
- Repeat with normal usage. Make a short test in the actual Zoom, Teams, Discord, or OBS setup because that software may add its own processing.
- Ask a listener who was not watching the test. Have them identify which take keeps your voice most natural while still hiding the noise. A blind listener reduces the effect of brand expectations.
Choose the least aggressive setting that makes the noise acceptable. A filter that removes every key strike but damages word endings can reduce intelligibility more than a quieter keyboard in the background.
Which is better for common use cases?
Windows streamer with an RTX card
Start with NVIDIA Broadcast. It matches the platform and hardware you already have, targets microphone noise and room echo, and avoids a recurring Krisp subscription for basic outgoing cleanup. Test it in the complete OBS chain, especially if your GPU is also rendering a demanding game. Move to Krisp if you need incoming cleanup, use multiple operating systems, or prefer its virtual-microphone workflow and meeting features.
Streamer without an RTX card
Start with Krisp rather than planning around unsupported Broadcast hardware. The seven-day trial gives you a way to test your own keyboard, fan, and room before paying. If you later buy an RTX card for gaming or encoding, reassess Broadcast then; do not buy a GPU solely because a percentage claim suggests one suppressor will sound better.
Rank #4
- Powered by the NVIDIA Blackwell architecture and DLSS 4 OC mode: 2640MHz/Default mode: 2610MHz (Boost Clock)
- Military-grade components deliver rock-solid power and longer lifespan for ultimate durability
- Protective PCB coating helps protect against short circuits caused by moisture, dust, or debris
- 3.125-slot design with massive fin array optimized for airflow from three Axial-tech fans
- Phase-change GPU thermal pad helps ensure optimal thermal performance and longevity, outlasting traditional thermal paste for graphics cards under heavy loads
Zoom or Teams participant who wants both sides cleaner
Start with Krisp because its product comparison explicitly includes incoming as well as outgoing audio. Verify the call application’s own echo cancellation and noise suppression settings so they do not fight the Krisp path. If the other participant’s audio is already clean and only your microphone is troublesome, Broadcast may be sufficient on a compatible Windows PC.
Free tools Windows power users keep installed
One-click scans. No signup required.
Mac user
Use Krisp as the practical starting point because Broadcast is described as Windows-only and RTX-dependent. Check CPU load during a long call, particularly on an older Mac, and use headphones when testing to prevent acoustic echo.
Room with strong reverberation
Try Broadcast’s Room Echo Removal when you have compatible RTX hardware. Also improve the physical room: move closer to the microphone, lower the input gain, and add soft furnishings. Software can reduce reflected sound, but it cannot restore speech detail that was never captured clearly.
Troubleshooting: symptoms, causes, and fixes
The destination app still hears the raw microphone
- Reopen the app’s audio settings and select the processed Broadcast or Krisp virtual microphone, not the hardware microphone.
- Check that the processing application is running and shows live input.
- Remove duplicate audio sources in OBS or the call app; a raw source can make the processed one appear ineffective.
The voice sounds robotic, hollow, or chopped
- Lower suppression strength and repeat the same sentence.
- Move the microphone closer and reduce gain so the voice is much louder than the noise.
- Disable Room Echo Removal temporarily to determine whether reverberation processing, rather than noise removal, is causing the character.
- Check whether the call app is applying a second aggressive filter.
Keyboard clicks remain audible
- Use the same keyboard pattern during testing; sporadic clicks may fall outside a filter’s strongest conditions.
- Reduce the distance between your mouth and microphone or reposition the microphone away from the keyboard.
- Increase suppression gradually, stopping when consonants begin to disappear.
Broadcast will not install or activate
- Confirm Windows 10 64-bit or a supported newer Windows configuration, at least 8 GB RAM, a listed RTX-class GPU, and compatible drivers.
- Verify the exact GPU model rather than assuming every GeForce card is RTX-compatible.
- Install or update the manufacturer’s compatible driver, reboot, and test again.
There is echo or feedback
- Use headphones while monitoring.
- Ensure only one application owns the processed input and that OBS is not monitoring the same source back into the speakers.
- In meetings, check which device is selected for both microphone and speaker; a virtual microphone should not also be used as the speaker output.
GPU or CPU load affects a stream
- Compare a local recording with processing enabled and disabled while the game and encoder are under normal load.
- Reduce game settings or move processing to the option that leaves stable frame time and audio sync.
- If the RTX system is already saturated, Krisp’s lack of a dedicated-GPU requirement may be useful, but measure CPU impact rather than assuming it is free.
Cost, hardware, and long-term value
Broadcast’s software is presented as free, but it requires qualifying RTX hardware and Windows. For an existing RTX owner, that makes the marginal cost of basic outgoing cleanup low. For someone on a Mac or a non-RTX PC, the relevant comparison is not “free versus paid”; it is the cost of compatible hardware, power, and setup versus Krisp’s subscription.
Krisp lists a seven-day trial, then Core at $16 monthly or $8 monthly billed annually, and Advanced at $30 monthly or $15 monthly billed annually, with unlimited noise cancellation in both listed plans. Annual billing lowers the displayed monthly equivalent but commits you to the annual payment schedule. Confirm cancellation terms and the final regional price at checkout.
Meeting notes can add value for people who would otherwise pay for a separate note-taking service, while streamers may care more about a reliable virtual microphone than about meeting features. Evaluate the features you will actually use rather than paying for a higher tier solely for the word “advanced.”
Decision checklist
- Are you on Windows, or do you need Mac support?
- Do you already own a GeForce RTX 2060, Quadro RTX 3000, TITAN RTX, RTX Spark, or higher qualifying GPU?
- Is your priority outgoing microphone cleanup, incoming audio cleanup, or both?
- Do you need one virtual microphone shared by Discord, OBS, and recording tools?
- Is room echo a bigger problem than keyboard or fan noise?
- Can your CPU or GPU spare processing headroom during a real stream?
- Will a seven-day trial answer your question before a Krisp subscription begins?
- Have you compared level-matched recordings with your own voice and noise?
Final answer
For a Windows streamer who already has a qualifying RTX card, NVIDIA Broadcast is the sensible first install for free outgoing cleanup, especially when room echo matters. For Mac users, non-RTX systems, mixed-device calls, incoming-audio cleanup, or a documented virtual-microphone route into OBS and Discord, Krisp is the more flexible starting point. Neither product has a current independent test proving a universal sound-quality victory. Use the same microphone, sentence, noise, and app for an A/B test, then choose the version that preserves your consonants and natural tone with the least audible processing.
