Krisp

We’ve all been on the call where the other person sounds like they’re in a wind tunnel. Krisp exists to make that person you — no wait, to make sure that’s never you. It’s the AI noise cancellation tool that removes background sound from your microphone in real time, so cafés, home construction, and barking dogs simply disappear from your calls. It became a staple of remote work almost overnight.

This guide covers what Krisp is, how it works, its pricing, and its limits.

What is Krisp?

Krisp is an AI-powered audio processing tool that removes background noise, echo, and other voices from your microphone in real time. It works at the system level: you select Krisp as your microphone in any app, and it cleans the audio before it’s transmitted — so the person on the other end hears only you.

It also cleans recorded audio: podcasts, interviews, voice memos, and videos can be processed to remove noise after the fact.

How Krisp works

1. Install Krisp on Windows or macOS.
2. Select it as your microphone in Zoom, Teams, Meet, or any app.
3. Speak normally — Krisp separates your voice from background sound in real time.
4. For recordings, drop audio files into Krisp to clean them up.

The key architectural point: processing happens on your device, so your raw audio isn’t uploaded for analysis — just the clean output goes to the call.

Who is Krisp for?

• Remote workers taking calls from anywhere.
• Students in dorms and shared spaces.
• Podcasters and voiceover artists without studios.
• Sales and support teams whose audio quality matters professionally.

Pricing

Krisp is freemium: a free tier with a weekly allowance of noise-cleaned minutes (great for light users), and Pro and Business plans with unlimited minutes and advanced features like call transcription. Check krisp.ai for current free limits.

Advantages

• Dramatic quality jump — calls sound studio-clean from anywhere.
• Works everywhere — no app-specific integration needed.
• On-device privacy — raw audio never leaves your machine.
• Recording cleanup — a second life for noisy files.
• Free tier enough to prove the difference.

Limitations and honest considerations

• Minute limits on free tier — heavy callers need Pro.
• Not perfect on extreme noise — very loud or overlapping sound can still leak.
• Occasional voice artifacts — aggressive filtering can slightly alter voice tone.
• System overhead — a small resource cost on older machines.

Alternatives and comparisons

Alternatives include Nvidia Broadcast (for Nvidia GPU users), NVIDIA RTX Voice, and built-in noise reduction in Zoom and Teams. Krisp’s edge: it’s hardware-agnostic and works in any app. For podcast production beyond noise removal, see our podcasting resources or tools like TTSMaker.

The bottom line

Krisp is one of those tools you don’t realize you need until you hear the difference — and then you can’t live without it. For anyone who takes calls or records audio outside a studio, it’s a small install with an outsized professional impact. Try the free minutes on your next noisy call.

Tip: Install it before your next important call from a café — the moment your voice arrives clean while the background disappears is the entire sales pitch.
