Krisp

Krisp is the simplest and most effective solution to a universal remote work problem: your environment isn’t a professional recording studio, but your calls need to sound like it is. The app sits at the operating system level between your microphone and any application that uses it, filtering noise in real time before it reaches the other person.

The noise removal covers the obvious sources — keyboard clicking, HVAC systems, street traffic, apartment building sounds — but what distinguishes Krisp is the background voice filter. Most noise cancellation tools remove non-voice sounds. Krisp also removes other human voices: if your kids are talking nearby, your housemate is on their own call in the background, or you’re in an open plan office surrounded by other conversations, Krisp suppresses those voices while preserving your own. The filtering is not perfect at extreme levels, but it’s far better than any alternative.

Setup takes under two minutes. Install the app, select “Krisp Microphone” and “Krisp Speaker” in your system or app audio settings, and noise cancellation is active. Because it works at the OS level, there’s nothing to configure per-app — it works automatically with Zoom, Teams, Google Meet, Slack, Discord, and any other application that uses your microphone.

The free tier offers 60 minutes of noise cancellation per day — enough to evaluate the product. The Pro plan ($8/month) removes all time limits and adds meeting transcription features. The Business plan adds team management and analytics.

For remote workers, customer support teams, online educators, and anyone who makes regular calls from imperfect acoustic environments, Krisp’s cost-to-value ratio is one of the highest in professional productivity software.
