If you take client calls, record podcasts, or work from a busy household, finding the best app to remove background noise is not a luxury. It is a basic requirement for sounding professional. Krisp handles this job better than almost any other tool on the market because it works at the system level, meaning it cleans your audio before it even reaches Zoom, Teams, or your recording software.
The platform uses on-device AI to separate human voices from ambient sounds like keyboard clicks, traffic, or barking dogs. You do not need to fiddle with complex audio routing or buy expensive hardware to get studio-quality sound. It simply works in the background, which is exactly what busy professionals need.
However, it is not free forever. The free tier gives you a taste, but serious users will need the paid Core plan at $8 per month when billed annually. For that price, you get unlimited noise cancellation, which easily pays for itself if it saves you from having to explain away background noise on an important call. See current pricing to check if the annual discount makes sense for your workflow.

Quick Verdict: Is This Actually Worth Trying?
If you regularly host meetings or create audio content, this software is an absolute necessity. It eliminates the embarrassment of apologizing for a noisy environment and lets your actual message take center stage. immediately.
What You Actually Get in the Free Trial
Krisp offers a 7-day free trial that unlocks all premium features without requiring a credit card. This is a massive advantage because you can test the noise cancellation in your actual work environment before committing any money. You get to see exactly how well it handles your specific background noise, whether that is a loud air conditioner or a roommate talking in the next room.
During the trial, you also get access to unlimited AI transcription and meeting notes. The app can join your calls as a bot-free participant, transcribe the conversation, and summarize action items automatically. This alone makes the trial worth starting, even if you are only on the fence about the noise cancellation piece.
The mobile app is also included, meaning you can clean up your audio on the go. Whether you are taking a call from your phone in a coffee shop or recording a quick voice memo, the same AI processing applies. Get started with Krisp to test these features risk-free for a full week.
The Good Stuff and Real Limitations
The strongest advantage of this tool is its universal compatibility. It works with literally any application that uses a microphone, from Google Meet and Slack to OBS and local recording software. You select the virtual microphone in your app settings, and the cleanup happens automatically without any extra configuration.
Another major benefit is the low impact on your computer's performance. Because the AI processing happens locally on your device rather than in the cloud, you avoid the latency and internet dependency that plague web-based audio tools. Your calls remain smooth, and your voice stays perfectly synchronized with your video.
The main limitation is that it requires a subscription for unlimited use. The free version restricts you to a limited number of noise cancellation minutes per week, which is fine for testing but useless for daily professional use. Additionally, while it is incredible at removing steady background noise, it can occasionally struggle with sudden, extremely loud overlapping voices.
Pricing and How It Compares to Alternatives
The Core plan costs $16 per month if you pay monthly, or $8 per month if you commit to an annual billing cycle. This pricing is competitive when you consider that it replaces the need for a physical soundproof booth or a high-end dynamic microphone. The Advanced plan jumps to $30 per month, adding features like unlimited AI accent conversion and deeper team management tools.
When you compare this to built-in noise suppression in apps like Zoom or Discord, this tool is significantly more powerful. Native app filters often make voices sound robotic or underwater when the background noise gets loud. It maintains natural voice fidelity while aggressively cutting out the interference, which is why it remains the top choice for professionals.
For users who only need occasional audio cleanup for pre-recorded files, free tools like Audacity with noise reduction plugins might suffice. But for real-time communication, nothing beats a dedicated, always-on solution. If you are serious about your audio quality, the subscription is a minor expense for the credibility it protects.
What You Actually Get in the Free Trial
Krisp gives you a 7-day free trial that unlocks every premium feature. You do not need to enter a credit card to start testing it. This lets you evaluate the noise cancellation in your actual work environment before spending a dime.
During this week, you also get unlimited AI transcription and meeting notes. The app joins your calls as a bot-free participant to summarize action items automatically. This alone makes the trial worth starting, even if you are only on the fence about the audio cleanup.

Pricing and Why You Need to Get It
The Core plan costs $16 per month if you pay monthly. It drops to $8 per month if you commit to an annual billing cycle. This pricing is highly competitive when you consider what it replaces.
It eliminates the need for a physical soundproof booth or a high-end dynamic microphone. When you are searching for the best app to remove background noise, you need a solution that operates seamlessly. If you are serious about your audio quality, the subscription is a minor expense for the credibility it protects.
The Advanced plan jumps to $30 per month for power users. This tier adds features like unlimited AI accent conversion and deeper team management tools. It is designed for larger organizations that need granular control over their workspace settings.
Remote workers and podcasters will see the most immediate return on investment. A single professional client call can justify the entire annual subscription cost. Delaying this purchase means you continue risking your professional reputation on every single call.
Beginners might wonder if they can handle the setup. The installation process takes less than two minutes on both Windows and Mac. You just install the app, select it as your microphone, and start talking.
This tool also pairs perfectly with other productivity platforms. Combining it with transcription services ensures your final notes are completely free of audio artifacts. You get a clean, professional workflow from the moment you hit record.

| Tool | Best For | Main Strength | Main Drawback | Starting Price |
|---|---|---|---|---|
| Krisp | Real-time calls and recordings | Universal app compatibility | Requires subscription for unlimited use | $8/mo (annual) |
| Fireflies.ai | Meeting transcription and notes | Deep CRM integrations | Does not cancel background noise in real-time | Free tier / $10/mo |
| Built-in App Filters | Casual users | Completely free | Makes voices sound robotic or underwater | $0 |
How It Compares to Other Options
There are a few other ways to handle noisy environments, but they all come with significant compromises. You can try relying on the built-in noise suppression features inside Zoom or Microsoft Teams. These native filters are free and require no extra installation.
The problem is that these basic filters heavily degrade your audio quality when the background noise gets loud. Your voice will often sound robotic, underwater, or completely cut out when you move slightly. They simply cannot compete with dedicated AI processing.
Another popular option is NVIDIA Broadcast, which offers incredible noise cancellation for free. However, it is strictly locked to users who own expensive RTX graphics cards. If you use a standard MacBook or a laptop without high-end gaming hardware, this option is completely unavailable to you.
To help you decide which route makes the most sense for your specific setup, I have broken down the main differences below. This will show you exactly where the paid option outperforms the free alternatives.

| Tool | Best For | Main Drawback | Starting Price |
|---|---|---|---|
| Krisp | Universal compatibility across all calling apps | Requires a paid subscription for unlimited use | $8/mo |
| NVIDIA Broadcast | Gamers and streamers with high-end hardware | Hardware locked exclusively to RTX graphics cards | $0 |
| Built-in App Filters | Casual users taking occasional calls | Audio quality degrades heavily when noise is loud | $0 |
| Fireflies.ai | Broader meeting intelligence and CRM syncing | Does not cancel real-time background noise | $10/mo |
If you take calls across multiple different platforms and need pristine audio everywhere, Krisp is the absolute best choice. If you already own a high-end gaming PC with an RTX graphics card, you can save money by using NVIDIA Broadcast for free. If your main goal is automated meeting notes and CRM syncing rather than just audio cleanup, a broader tool like Fireflies.ai makes more sense.
My Honest Take: Should You Get It?
Professional audio is no longer optional if you want to be taken seriously on video calls. Trying to manually edit audio or constantly apologizing for your environment only slows down your workflow and damages your credibility. Krisp solves this problem completely by working silently in the background.
The 7-day free trial gives you more than enough time to test it in your actual workspace without entering a credit card. Once you experience a call without keyboard clicks or background chatter, you will never want to go back to raw microphone audio. The setup takes less than two minutes and requires zero technical knowledge.
For remote workers, podcasters, and sales professionals, this software easily pays for itself in saved time and protected reputation. Stop letting background noise distract from your message and start sounding like the professional you are. The annual plan brings the cost down to just eight dollars a month, which is less than a single coffee shop visit.
Quick Questions Answered
Does Krisp drain my laptop battery?
The AI processing is highly optimized and uses minimal system resources. You might notice a very slight battery impact, but it will not cause your fans to spin up or slow down your computer during calls.
Will my voice sound robotic to the other person?
No, the AI is trained specifically to isolate human vocal frequencies. Unlike basic noise gates that cut off the ends of your words, it preserves your natural voice tone while removing everything else.
Can I use it on my phone?
Yes, the mobile app is included in all paid plans. This means you can clean up your audio on the go, whether you are taking a call from a busy coffee shop or recording a quick voice memo.
What happens if I cancel my subscription?
Your account simply reverts to the limited free tier. You will still get a small allowance of noise cancellation minutes each week, but you will lose access to the unlimited features and AI transcription.
