Should you build your own Krisp?
Real-time AI noise cancellation and meeting voice enhancement
You can build post-processing and maybe route audio through open models, but real-time low-latency virtual-device noise cancellation is not a one-sitting web app.

Build me a noise-cleanup tool to replace Krisp for recordings, not live calls. Requirements:
- Be honest in the README up front: real-time suppression as a virtual microphone
needs an OS-level audio driver and millisecond latency. That is Krisp's actual
product and it is out of scope here. This tool cleans audio files after the fact.
- A CLI: `denoise in.wav` (mp3/m4a accepted, decoded via ffmpeg) writes
in.clean.wav next to the original, original untouched.
- Use RNNoise for the suppression pass (ffmpeg's arnndn filter with a downloaded
model file is the easy route), then a loudnorm pass so voice levels come out
consistent.
- A watch mode with chokidar: drop files into ~/Denoise/in/ and cleaned versions
appear in ~/Denoise/out/ with the same names.
- Batch mode for whole folders, with a printed before/after noise estimate per file.
- Node wrapping ffmpeg, or a plain bash script if that ships simpler. No server,
no GUI.
- Fully local and offline: no accounts, no telemetry, no API calls.
- Out of scope: live call processing and a virtual audio device. For live calls the
README should point me at the OS's built-in voice isolation instead.
- README: ffmpeg and RNNoise model install, one-line usage examples.The prompt opens pre-filled in your agent. Review it before running. · this prompt is generated from the build plan · improve it via PR
What would building your own look like?
Use an open noise-suppression model as a virtual microphone or post-process recordings before sending them to calls or files.
What you will need
- audio DSP library
- OS-level virtual audio device
- model/runtime optimized for low latency
- macOS/Windows audio permissions
They pay because audio cleanup must be instant and invisible during real calls.

Is it cheaper to build or buy Krisp?
Adjust the numbers: hours to build, your hourly rate, running costs and the subscription price.
Over 24 months, subscribing is cheaper.
Starting hours estimated from the analysis (multi-day). Does not price what you give up (support, integrations, security).
Can I rebuild Krisp?
Kinda. The core of Krisp is buildable in a weekend with the prompt on this page, but there are real gaps: low-latency virtual microphone, polished app switching. Read the honest list above before committing.
How much does Krisp cost?
Krisp costs about $16/mo (Core, checked 10/20/2026), which is $96 per year.
What do I lose by replacing Krisp?
Honestly: low-latency virtual microphone; polished app switching; model quality; meeting integrations; admin controls. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to Krisp?
Yes: EasyEffects (Krisp for Linux tinkerers: system-wide cleanup, zero magic account, several knobs.) NVIDIA Broadcast (Excellent noise removal, free in money and expensive in RTX silicon.) The prompt is for when you want it exactly your way.
