I still remember the exact moment I realized I needed Krisp. I was on a client call — the kind of call where I needed to sound professional, articulate, and in control. Five minutes in, construction started outside my window. Jackhammers. Not distant, gentle construction. The kind that vibrates through the floor and makes you feel like the building is being dismantled around you. I apologized to the client. I muted myself while they were speaking. I prayed for pauses in the noise. The call limped along, but I could feel my credibility eroding with every burst of jackhammer. Afterward, a colleague mentioned Krisp. "It removes background noise in real time," they said. "The people on your calls will not hear anything except your voice." I downloaded it that afternoon. The next time construction started, I watched the Krisp indicator light up — detecting noise, filtering it out — while my client continued talking, completely unaware that a construction crew was tearing up the street thirty feet from my window.

That was over two years ago. Since then, Krisp has been running on my computer almost constantly. Client calls, podcast recordings, team meetings, virtual presentations, even casual video chats with friends. I have tested it with every kind of background noise I have encountered: construction, traffic, barking dogs, crying babies, coffee shop chatter, keyboard typing, wind, rain, and the chaotic acoustics of hotel rooms and airport lounges. I have recommended it to colleagues who work from home with small children. I have watched it save important calls that would otherwise have been ruined by unpredictable noise.

This review is based on all that real-world use. I will show you exactly what Krisp can do, where it struggles, how much it costs, who should use it, and who should look elsewhere. If you make calls or recordings in environments you cannot fully control — and honestly, who does not? — this is the review you need.

What Exactly Is Krisp?

Krisp is an AI-powered noise cancellation application that works in real time across your entire computer's audio system. It was founded by Davit Baghdasaryan and Artavazd Minasyan, two Armenian engineers who had previously worked on speech recognition technology. Their insight was that while many applications had built-in noise suppression, the quality was inconsistent across platforms. A tool that worked system-wide — filtering noise before it reaches any application — would provide a more reliable solution.

Krisp works by creating a virtual audio device on your computer. You set Krisp as your microphone and speaker in your system settings or individual applications. When you speak, Krisp's AI analyzes your audio in real time, identifies sounds that are not human speech, and removes them before the audio reaches your call or recording application. The processing happens locally on your device, with no audio sent to the cloud. The result is that the people on the other end of your call hear your voice — clear and isolated — and almost nothing else.

Krisp works in both directions. The microphone filter removes background noise from your environment so others hear only your voice. The speaker filter removes background noise from other people's calls — so if you are on a call with someone in a noisy environment, Krisp filters their audio too. The tool integrates with virtually any application that uses a microphone or speaker: Zoom, Microsoft Teams, Google Meet, Slack, Discord, recording software, streaming applications — anything that uses audio.

How I Tested Krisp for This Review

I have been using Krisp for over two years, but for this review I conducted a focused four-week testing period. Here is what I tested:

1. Background noise scenarios: Testing Krisp against construction noise, traffic, barking dogs, crying children, coffee shop chatter, keyboard typing, wind, rain, and appliance noise.
2. Voice quality preservation: Evaluating whether Krisp degraded voice quality or introduced artifacts while removing noise.
3. Cross-application compatibility: Testing Krisp with Zoom, Google Meet, Microsoft Teams, Slack, Discord, OBS Studio, Audacity, and Descript.
4. CPU and memory impact: Measuring system resource usage during active noise cancellation.
5. Speaker filter testing: Evaluating how well Krisp filtered noise from other participants' audio during calls.
6. Recording quality: Comparing recordings made with and without Krisp in noisy environments.
7. Side-by-side comparison: Comparing Krisp's noise cancellation against built-in solutions in Zoom, Teams, and Google Meet.

I used the Pro plan and tested Krisp on both Mac and Windows. I focused on real-world scenarios — the kinds of unpredictable noise that actually disrupts calls and recordings.

What Krisp Does Really Well

Krisp has earned its strong reputation through consistent, reliable performance. Here is where it excels.

1. Noise Cancellation That Works Remarkably Well

This is the single most important thing about Krisp, and it delivers. The noise cancellation is genuinely effective. It removes an impressive range of background sounds — construction, traffic, barking dogs, crying children, keyboard typing, coffee shop chatter, wind, rain, appliance hums — while preserving your voice clearly. People on your calls genuinely will not hear the noise in your environment.

I tested this systematically by recording myself speaking in various noisy environments, once with Krisp enabled and once without. The difference was dramatic. Without Krisp, background noise was clearly audible and distracting. With Krisp, my voice was clean and isolated. The recordings were not just better — they were usable in situations where recording would otherwise have been impossible. A recording made next to a running washing machine sounded like it was made in a quiet room. A recording made with construction noise outside sounded clean and professional.

The real-time aspect is crucial. Krisp does not process audio after the fact. It filters noise as you speak, with latency low enough to be imperceptible in conversation. This means you can use it on live calls, not just recordings. For remote workers, digital nomads, and anyone who takes calls from unpredictable environments, this real-time capability is transformative. You can take an important client call from a coffee shop, an airport lounge, or a home with active children, and sound like you are in a quiet office.

2. System-Wide Integration With Any Application

Krisp works at the operating system level as a virtual audio device. This means it integrates with every application on your computer — not just the ones that have built Krisp-specific integrations. Set Krisp as your microphone in your system settings, and every application sees the filtered audio. You do not need to configure noise cancellation separately in Zoom, Teams, Meet, Slack, Discord, your recording software, and your streaming application. Krisp handles all of them.

This system-wide approach is a significant advantage over application-specific noise cancellation. Zoom has built-in noise suppression. Teams has built-in noise suppression. Google Meet has built-in noise suppression. Each works differently, with different quality levels and different controls. If you use multiple communication platforms — and most professionals do — managing noise cancellation across all of them is a headache. Krisp solves this by providing consistent, high-quality noise cancellation across everything. Set it once, and it works everywhere.

3. The Speaker Filter Is an Underrated Feature

Krisp's speaker filter removes background noise from incoming audio — the sounds coming from other people on your calls. This feature does not get as much attention as the microphone filter, but it is genuinely valuable. If you have ever been on a call where someone's background noise made it hard to focus — their keyboard clicking, their dog barking, their coffee shop's background music — you know how distracting it can be.

The speaker filter cleans up incoming audio so you hear voices clearly regardless of other participants' environments. This is particularly useful for managers who lead meetings with multiple remote participants, podcast hosts recording interviews with guests in uncontrolled environments, and anyone who regularly participates in large calls where background noise from multiple sources compounds. The speaker filter cannot fix audio that is fundamentally broken, but it significantly reduces common background noises that make calls harder to follow.

4. Local Processing for Privacy and Speed

Krisp processes all audio locally on your device. Your voice and the background noise in your environment never leave your computer. This is a significant privacy advantage over cloud-based noise cancellation solutions. For professionals handling confidential conversations — therapists conducting telehealth sessions, lawyers in client consultations, executives in strategic discussions — local processing ensures that sensitive audio is not transmitted to third-party servers.

Local processing also means Krisp works without an internet connection (after initial setup), with very low latency. There is no network round-trip for audio processing. The AI runs on your device's processor, and the filtering happens in near real-time. For live conversations where even small delays are disruptive, this local architecture is essential.

Where Krisp Falls Short

Krisp is excellent, but it has real limitations. Here is where it struggles.

1. Voice Quality Can Sound Slightly Processed

Krisp's noise cancellation is aggressive, and this aggressiveness can affect your voice quality. In quiet environments where there is no noise to cancel, Krisp sometimes introduces a slight digital quality — a subtle artificialness that makes your voice sound slightly processed. It is not dramatic, and most listeners will not notice or care, but it is there. Audio professionals and those with sensitive ears may find it noticeable.

The voice quality impact is more noticeable with certain microphone types and voice characteristics. Deeper voices may sound slightly thinner. Higher voices may sound slightly sharper. The effect is subtle, but if you are recording content where audio quality is paramount — professional voiceovers, audiobook narration, high-production podcasts — you may prefer to record in a genuinely quiet environment without noise cancellation rather than relying on Krisp to clean up a noisy space.

2. Not Effective for All Types of Noise

Krisp is designed to remove consistent, predictable background noise — the kinds of sounds that are clearly distinct from human speech. It works well on construction, traffic, keyboard typing, appliance hums, and general ambient noise. It is less effective on sounds that overlap with human speech frequencies or are irregular and unpredictable. Loud music with vocals can confuse the AI. Other people talking nearby — distinct conversations in a coffee shop, for example — may not be fully filtered because the AI has difficulty distinguishing between your voice and other human voices.

Krisp also struggles with sudden, sharp noises — a door slamming, a plate dropping, a car horn very close by. These sounds may be reduced but not eliminated, and they can break through the noise cancellation momentarily. For environments with unpredictable human speech or sudden loud noises, Krisp helps but does not provide complete isolation.

3. Resource Usage Can Be Significant

Because Krisp processes audio locally using AI, it consumes system resources. On modern computers with capable processors, the impact is modest — a few percentage points of CPU usage. On older or less powerful machines, the resource consumption can be more noticeable, especially during long calls or when running other demanding applications simultaneously.

I tested Krisp on a five-year-old laptop during a video call with screen sharing, and I noticed some system slowdown. The noise cancellation still worked, but the overall experience was less smooth. If you use an older computer or regularly push your system to its limits, Krisp's resource requirements may be a consideration. On any reasonably modern computer, the impact is minor and easily worth the benefit.

4. The Free Plan Is Very Limited

Krisp's free plan offers 60 minutes of noise cancellation per day. This is enough for a short call or meeting, but not for a full day of work. If you use Krisp for multiple calls, long meetings, or continuous recording, you will exhaust the free minutes quickly and need to upgrade to the Pro plan at $12 per month (billed annually).

The Pro plan removes the daily limit and adds features like accent localization and meeting transcription. At $12 per month, it is reasonably priced for a tool that solves a genuine problem. But for users who only need occasional noise cancellation, the 60-minute daily limit may be sufficient, or the price may not be justified.

Krisp vs. The Competition

Krisp competes with built-in noise cancellation features and a few standalone alternatives. Here is how it stacks up.

Krisp vs. Built-in Noise Suppression (Zoom, Teams, Meet)

Zoom, Microsoft Teams, and Google Meet all include built-in noise suppression. These features have improved significantly and work reasonably well for common background noises. Krisp's noise cancellation is generally more effective — it removes a wider range of sounds more aggressively. But the built-in solutions have a key advantage: they are already there, with no additional software, no additional cost, and no system resource overhead beyond what the application already uses. For many users, built-in noise suppression is good enough. Krisp is for users who need better noise cancellation than the built-in options provide, or who want consistent noise cancellation across all applications.

Krisp vs. Nvidia Broadcast

Nvidia Broadcast offers similar AI noise cancellation, but it requires an Nvidia RTX graphics card. For users with compatible hardware, Nvidia Broadcast is a strong free alternative. Krisp works on any computer regardless of graphics card and has no hardware requirements beyond a reasonably modern processor. For users with Nvidia RTX GPUs, Broadcast is worth testing alongside Krisp. For everyone else, Krisp is the more accessible option.

Krisp vs. Adobe Podcast

Adobe Podcast enhances audio after recording — you upload a file and the AI processes it. Krisp cancels noise in real time during recording or live calls. They serve different stages of the workflow. Use Krisp to prevent noise from entering your recordings in the first place. Use Adobe Podcast to clean up recordings that were made without noise cancellation. Many creators use both. I reviewed Adobe Podcast earlier in this series.

Pros and Cons Summary

Pricing Overview

*Prices shown are annual billing. Monthly billing is $15/month. The free plan is sufficient for occasional use. The Pro plan is necessary for regular daily use. Team and enterprise plans are available with volume pricing.

Who Should Use Krisp?

Based on my testing, here is who will benefit most from Krisp:

• Remote workers in noisy environments: If you work from home with children, pets, or urban noise, Krisp lets you take calls without your environment announcing itself to every participant.
• Digital nomads and frequent travelers: Coffee shops, co-working spaces, airport lounges, hotel rooms — Krisp makes any space viable for professional calls.
• Podcasters and content creators: When you cannot control your recording environment, Krisp prevents background noise from ruining otherwise good takes.
• Therapists, lawyers, and confidential professionals: Local processing means sensitive conversations stay private. No audio is sent to the cloud.
• Anyone who uses multiple communication platforms: Consistent noise cancellation across Zoom, Teams, Meet, Slack, and everything else simplifies your audio setup.

Who Should Look Elsewhere?

• Those who always record in controlled, quiet environments: If you have a sound-treated studio and never take calls from unpredictable locations, Krisp may not add value and could subtly degrade your audio quality.
• Users satisfied with built-in noise suppression: If Zoom, Teams, or Meet's built-in noise cancellation is sufficient for your needs, Krisp may not justify its cost and system resource usage.
• Audio professionals seeking pristine recording quality: Krisp's processing can introduce subtle artifacts. For professional voiceover or music recording, acoustic treatment and a quiet environment are better solutions.
• Occasional users with light call schedules: The free plan's 60-minute daily limit may be sufficient. If you rarely exceed that, the Pro plan may not be worth the investment.

Tips for Getting the Most Out of Krisp

After two years of regular use, here are my best tips for using Krisp effectively:

1. Test Krisp with your specific microphone and environment. Noise cancellation effectiveness varies with microphone type and background noise characteristics. Do a test recording before relying on Krisp for an important call.
2. Turn Krisp off when recording in a quiet studio. If you are in a genuinely quiet, acoustically treated space, Krisp's processing may subtly degrade your voice quality. Use it when you need it, not as a default.
3. Enable the speaker filter for large meetings. When multiple participants have varying audio quality, the speaker filter helps you hear everyone clearly by reducing their background noise.
4. Monitor your CPU usage on older computers. If you experience system slowdowns during calls, check whether Krisp is contributing. You can toggle it off temporarily for less critical calls.
5. Combine Krisp with a good microphone. Noise cancellation works best when your voice is captured clearly to begin with. A decent microphone plus Krisp produces much better results than a poor microphone with Krisp trying to compensate.
6. Keep Krisp updated. The AI models improve over time. Regular updates bring better noise cancellation, lower resource usage, and new features.

My Experience After Two Years of Using Krisp

I started using Krisp to solve a specific problem — construction noise outside my window. Two years later, it is one of those tools I do not think about until it stops working, and then I immediately remember why it matters. It runs quietly in the background, filtering out the chaos of daily life, making me sound professional regardless of what is happening around me.

Krisp has changed where I can work. I have taken client calls from coffee shops, airport lounges, hotel lobbies, co-working spaces, and a home with active children and barking dogs. In each of those situations, the people on the other end of the call heard a clean, professional voice. They had no idea about the noise around me. That freedom — the ability to be professionally present from almost anywhere — is genuinely valuable for remote workers and digital nomads.

The tool is not perfect. The slight voice processing is noticeable in quiet environments. It struggles with certain types of noise. The resource usage can be a factor on older machines. But for the core problem it solves — unwanted background noise disrupting your calls and recordings — Krisp is the most effective solution I have found. It is one of the first tools I install on any new computer, and it runs every day. For remote workers, content creators, and anyone who communicates professionally from unpredictable environments, Krisp is an essential utility.
