For most of last year, my work setup was a disaster zone of background noise. I run a small consulting practice from a converted bedroom in an apartment building where the upstairs neighbor seems to be auditioning for a tap dancing competition every Tuesday. Add in a temperamental espresso machine, a dog that barks at delivery drivers with theatrical commitment, and construction work two blocks over, and you have a recipe for client calls where I spend half the meeting apologizing for whatever just exploded in the background.
I had tried everything before looking for actual software. I bought a fancy condenser mic, then returned it because it picked up MORE ambient noise, not less. I bought a different mic with a cardioid pattern, draped blankets over my desk like I was building a pillow fort, and even started scheduling important calls during my neighbor’s gym hours. The breaking point came during a discovery call with a potential six-figure client when a fire truck went screaming past my window for what felt like a full minute. I muted, unmuted, apologized, and watched the prospect’s face do that polite-but-pained thing on Zoom. I knew I needed a real solution.
I found out about it the way I find out about most software now, which is some random person in a Slack community I’m in mentioning it offhand. They said something like “just use the noise cancellation thing, it’s free for individuals up to a point.” I googled around, landed on the site, and honestly was skeptical because the demo video sounded too clean to be real. But I figured a Krisp trial wasn’t going to cost me anything except ten minutes, so I downloaded it that night.
Setup took maybe four minutes. You install the app, it creates a virtual microphone and speaker on your system, and then in Zoom or Google Meet or whatever you select “Krisp Microphone” instead of your actual mic. That’s it. No configuration tree, no calibration phase, no setting up profiles. I tested it by recording myself talking while deliberately crinkling a chip bag next to my face and tapping my desk with a pen. When I played it back, I could hear myself perfectly and absolutely nothing else. The chip bag was just gone. I genuinely laughed out loud because it felt like a magic trick. My honest krisp ai review at that moment was that I assumed there had to be a catch.
The catch, sort of, is that the free tier limits you to 60 minutes of noise cancellation per day. For someone with three or four hour-long calls in a day, that runs out fast. I upgraded to the paid plan after about a week of bumping into the limit mid-meeting, which is a slightly annoying experience because the app warns you but you’re already in a call trying to focus on a client. Still, the pricing felt reasonable compared to the alternative, which was me genuinely considering renting a co-working space just for call privacy.
Now it just runs in the background constantly. I forget it’s there until I happen to take a call without it and someone says “wow, your audio sounds rough today.” It handles the dog barking, the espresso machine, keyboard clatter when I’m taking notes, and the upstairs tap recital. The one thing it does NOT handle perfectly is overlapping human voices. If my partner is on a call in the next room and her voice carries, Krisp sometimes lets fragments through, probably because the algorithm is trained to preserve speech, not eliminate it. So I still close the door.
The other quirk is that occasionally on the first second of unmuting, my own voice gets clipped slightly, like the noise cancellation is making sure I’m actually a human before letting the audio through. It’s a tiny thing but I’ve noticed clients sometimes miss my first word. I’ve started waiting a half-beat after unmuting now, which feels silly but works.
What genuinely annoyed me at first was that the meeting transcription and summary features are part of higher tiers, and the marketing kind of pushes you toward them. I don’t need AI meeting notes, I take my own, and I felt slightly nagged about it for the first month. Once I closed those prompts a few times it stopped pestering me.
There’s also a situation where I still record podcast interviews using a separate recording setup, because for high-fidelity production audio I want the raw uncompressed file, not the processed virtual mic output. So Krisp doesn’t replace everything in my audio toolkit, just the live call portion. Next I want to test whether it plays nicely with StreamYard for a webinar I’m running in February, because the noise floor in that recording is going to matter and my apartment is not getting any quieter.
