[Krisp](/tools/krisp) AI Review 2026: Noise Cancellation for Calls - Complete Analysis

Remote work has made one thing abundantly clear: background noise is the enemy of professional communication. Dogs barking, construction outside, kids playing, keyboard clacking—all of these can derail an important call. Krisp promises to eliminate these distractions using AI-powered noise cancellation that works with any application. After months of testing across various environments, here’s our comprehensive analysis of whether Krisp delivers on its promise. ## What is Krisp? Krisp is an AI-powered noise cancellation application that removes background noise from both your microphone and speaker during calls. Unlike hardware-based solutions, Krisp works as a software layer between your microphone and any communication application—Zoom, Google Meet, Microsoft Teams, Discord, or any other app that uses audio. The technology processes audio locally on your device using trained neural networks that can distinguish between human speech and background noise. This means your audio never leaves your computer, addressing privacy concerns while delivering real-time noise removal. ## How Krisp Works: Technical Overview Understanding Krisp’s architecture helps explain its capabilities and limitations: ### Virtual Audio Device Krisp installs as a virtual microphone and speaker on your system. When you select “Krisp Microphone” and “Krisp Speaker” in your communication app, audio routes through Krisp’s processing engine before reaching its destination. ### Local AI Processing All processing happens on your CPU—no cloud servers involved. This provides:

• Zero latency concerns from network delays
• Complete privacy since audio stays on-device
• Offline capability (though calls require internet anyway)
• Consistent performance regardless of server load ### Neural Network Models Krisp uses deep learning models trained on thousands of hours of audio containing various noise types. The models learn to identify the characteristics of human speech versus environmental sounds, then filter accordingly. ## Core Features Explained ### Bidirectional Noise Cancellation Krisp’s standout feature removes noise in both directions: Your Side (Microphone): Others won’t hear your background noise
• Keyboard typing
• Dogs barking
• Children playing
• HVAC systems
• Street traffic
• Coffee shop ambiance Their Side (Speaker): You won’t hear others’ background noise
• Helpful when colleagues have noisy environments
• Reduces distraction during group calls
• Makes poor-quality calls listenable ### Echo Cancellation Beyond noise removal, Krisp eliminates echo—the hollow, reverberating sound that occurs when speakers and microphones interact. This is particularly useful for:
• Users without headphones
• Conference room setups
• Laptop speakers in reflective environments ### Voice Enhancement Recent updates include voice enhancement that:
• Removes room reverb
• Reduces hollow audio artifacts
• Maintains natural voice tone
• Adjusts for poor microphone quality ### Meeting Transcription Krisp has expanded into meeting assistance:
