The best noise cancelling software for streaming is the one that improves your actual broadcast mix without removing wanted speech or disrupting performance. Keyboard clicks, fan noise and other voices are different test cases. Start with a short local recording of your setup rather than a promise that one filter will solve every sound problem.
This review examines Krisp as a live virtual-device filter, then compares relevant built-in and hardware-dependent alternatives. It covers the current trial, routing, subscription and limitations documented by the vendors. It does not report a hands-on listening test or measured game-performance result.
The purchase question is specific: does the selected tool help the signal your audience actually receives? A filter on your headphones is not proof that the broadcast captures the same filtered path. Verify the saved mix before starting a public stream.
Quick Verdict: Is This Worth Your Time?
Krisp is worth a trial when you need noise filtering across compatible desktop applications or on both microphone and incoming voice paths. The seven-day no-card trial gives you a way to evaluate that requirement. It does not establish that the result will beat an OBS filter already available in your setup.
An unpredictable room is a useful test case for live suppression. Test the actual keyboard, fan or background voice along with normal and quieter speech. Evaluate intelligibility and natural tone instead of expecting software to substitute for a suitable microphone position or a quieter space.
Strong suppression can remove wanted sound as well as noise, and clipping or poor capture may need a different fix. Krisp's placement guidance gives practical microphone starting points, while its headset guidance warns against overlapping processing. Treat those as setup checks before judging a paid filter.
Map the path you intend to filter
Write down the microphone, guest-call output and OBS source that carry the conversation. Decide which background sounds should be reduced and which sounds must remain, including alerts or game audio if they belong in the stream. This separates a speech-cleanup problem from the artistic choice of what the broadcast contains.
Make a brief local recording with your usual application mix running. Speak normally and softly, pause, and reproduce the recurring noise at a realistic level. Change one filter or route at a time and keep a note of the setting so that you can return to the previous result.
Listen to the saved recording at a similar playback level for each version. Check whether words remain intact, whether the guest path changed and whether an unfiltered duplicate is audible. These are evaluation steps for your own setup, not results from a benchmark performed for this review.

Who This Is Actually For
Consider Krisp if you use several desktop calling or recording applications and repeatedly need a filtered microphone or incoming voice path. For a stream that stays entirely within OBS, first evaluate the built-in filter against the same noise. The extra subscription and routing should have a clear purpose in your workflow.
Skip an additional filter if the current mix already meets the requirement or the computer cannot run it reliably with your normal workload. If a continuing free solution is essential, compare OBS or a compatible alternative before a paid trial ends. Check Krisp's current OS and hardware guidance rather than assuming it runs on every computer.

What You Actually Get in the Free Trial
The current Meeting AI offer is a seven-day trial without a credit card, with unlimited noise cancellation, transcription, recording and notes; accent features have limits. Use it to test the voice paths you need, not as evidence of a permanent free allowance. Check the current feature list before signup.
Meeting recording and note-taking are separate from local live filtering. The recording guide lists capture modes including Off, and the product overview distinguishes those features. Avoid enabling capture of guest or client conversations merely to evaluate noise suppression.
The current public offer lists paid Core and Advanced plans after the trial. It does not establish a continuing sixty-minute daily free tier. If the trial is not useful, choose a different workflow rather than budgeting around an old allowance.
The Good Stuff: Where This Tool Actually Shines
The Krisp virtual-device workflow is useful when the destination application supports it. Krisp's app-compatibility guidance requires selectable audio devices or system-level enforcement; its setup guide explains choosing physical hardware in Krisp and virtual devices in the app. This is more specific than a promise of universal compatibility.
For your own voice, choose the Krisp virtual microphone as the captured input in OBS. OBS documents input/output capture sources and warns that capturing the same device globally and in a scene can create echo. Make a recording to confirm that a second unfiltered route is not also present.
Krisp documents on-device noise filtering, while its security overview explicitly says Meeting Assistant recordings and transcripts can be stored in Krisp Cloud. Its privacy policy describes recording and note storage. Local suppression is therefore not a claim that every enabled feature keeps all content off servers.
Audio processing uses system resources, and Krisp lists CPU, RAM and background workloads among performance factors. Test the normal game, encoder and call workload together. Compare frame delivery, audio continuity and delay instead of relying on an unverified fixed CPU percentage.
Incoming and outgoing filtering require the corresponding paths to be configured. Krisp's noise-cancellation documentation distinguishes microphone and speaker processing. Check that OBS captures the filtered guest path you intended; hearing it in your headphones alone does not establish the broadcast route.
Diagnose the symptom before adding another effect
The OBS filter guide separates suppression, gate, expander and limiter functions. A gate closes the signal during quiet periods; it is not selective cleanup underneath ongoing speech. An expander reduces quieter signals according to a threshold and ratio, which can provide a less abrupt transition.
A limiter controls output peaks and is documented as the final filter. It does not reconstruct a microphone signal that was already clipped before processing. Identify the actual symptom and test the relevant control instead of stacking every available effect.
Pricing and Value: Is the Upgrade Worth It?
Core costs $8/user/month with annual billing or $16 monthly. Advanced is listed at $15/user/month annually or $30 monthly; both include noise cancellation, so do not upgrade solely to obtain an unlimited filter. Compare the current plan features and total billing commitment with the functions you actually need.

| Plan | Noise-filter access | Billing and buying check |
|---|---|---|
| Krisp seven-day trial | Unlimited noise cancellation during the advertised trial. | No credit card required; verify signup offer. |
| Krisp Core | Unlimited noise cancellation. | $8/user/month billed annually, or $16 monthly; evaluate the full term cost. |
| Krisp Advanced | Unlimited noise cancellation. | $15/user/month billed annually, or $30 monthly; choose only if the additional listed controls/features are needed. |
A filter cannot justify ignoring clipping, an unsuitable recording level or microphone placement. Correct the capture problem where possible, then evaluate suppression on what remains. Compare a normal voice passage as well as the loudest noise so that a quieter background does not hide damaged speech.
When Paying for a Filter Makes Sense
Pay when a representative local recording demonstrates an improvement you want to repeat and the normal workload remains usable. Live output needs a satisfactory route before the broadcast; later editing cannot change what listeners already heard. Keep the test focused on that immediate delivery requirement.
A useful trial can also show that the existing setup is sufficient or that a different filter suits the task better. Record the remaining problem before choosing a subscription. The availability of a free trial is a way to investigate fit, not proof that an upgrade is necessary.
If you choose a paid Krisp plan, check the renewal date and cancellation process before the next charge. Krisp's terms describe automatic renewal unless cancelled in advance and state that renewal charges are non-refundable. Compare the selected billing term with the recurring need you observed.
Krisp vs Cheaper or Built-in Alternatives
An OBS filter may cover the whole task at no additional cost. Compare a separate subscription only if it solves an audio-path requirement your current setup leaves unmet.
NVIDIA Broadcast is a relevant downloadable alternative for compatible RTX systems. Check the current GPU, RAM, Windows and driver requirements rather than relying only on the card series. The FAQ explains that effects consume resources; neither GPU acceleration nor a download eliminates performance impact.
SteelSeries Sonar is free Windows software inside GG, with routing, a mixer, EQ and microphone noise controls. SteelSeries' official release notes document ClearCast AI availability without a branded headset requirement. Consider the extra routing suite only if those broader functions help your workflow.
The OBS Noise Suppression filter is relevant when the required signal is already an OBS audio source. It includes RNNoise and other methods, with documented quality, resource and loud-noise limitations. It does not create a shared virtual microphone for every other application.

| Tool | Best fit and entry cost | Why choose it | Main limitation |
|---|---|---|---|
| Krisp | Compatible desktop apps; Core $8/user/month annual billing or $16 monthly. | You need selected virtual microphone/speaker paths across the apps you use. | Paid ongoing premium access; verify OS, routing and performance. |
| NVIDIA Broadcast | Compatible RTX Windows system; download available. | You want to evaluate hardware-accelerated microphone or incoming-audio effects. | Specific GPU, OS, RAM and driver requirements; effects still use resources. |
| SteelSeries Sonar | Windows GG audio suite; free. | You need app routing, mixer/EQ and microphone noise controls together. | Additional suite and routing; verify compatibility with your actual mix. |
| OBS Noise Suppression / RNNoise | OBS audio sources; included free in OBS. | You need a source-level filter within an existing OBS workflow. | No system-wide virtual device; test speech artifacts and resource use. |
Try OBS first when the whole requirement is filtering an OBS source. Consider NVIDIA Broadcast on a compatible system, or Sonar when its wider Windows routing suite solves a real need. Choose Krisp when the cross-application voice paths and trial result justify the subscription; no single tool wins every setup.
Choose from a representative stream recording
Keep the same microphone placement, game scene and guest application for each comparison. Include a normal explanation, a quiet passage and an energetic reaction if that reflects your stream. Decide whether laughter, music or room ambience belongs in the output before judging suppression solely by how quiet it becomes.
For NVIDIA Broadcast, the official setup guide documents virtual-device selection and warns that duplicate effects in other apps can conflict. It recommends enabling only needed effects to avoid unnecessary GPU use. Use the same principle when comparing alternatives: change one processing layer at a time.
Review the saved broadcast mix from beginning to end of the short test, including the guest channel and pauses. Check whether a scene change or device reconnection alters the route. If the clean signal is audible only in monitoring, fix capture before treating the trial as successful.
Write down the remaining limitation and the next concrete action. That might be changing a device selection, using a lighter filter, adjusting capture conditions or keeping the current setup. A comparison is useful when it identifies a reproducible workflow, even if it leads to no purchase.
My Honest Take: Should You Start the Trial?
Krisp has a documented role as a live virtual-device filter, but reliability and sound quality must be evaluated on the actual system. The best choice is the least complicated workflow that meets your delivery requirement. This review does not establish a universal listening-test winner or a fixed performance cost.
Use the no-card trial for an ordinary recording task before changing a live production setup. Compare the filtered result with the baseline and check the normal workload. If the result is not useful, keep the existing workflow or investigate the limitation before paying.
A subscription makes sense when a recurring need remains after trying the available built-in or compatible options. Compare the full selected term price with the improvement you observed. A quieter background is useful only if the delivered speech, routing and system performance remain suitable.
Frequently Asked Questions
