Can I vibecode Krisp?
// buildable in a weekend, but real gaps stay open
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.

The moat outweighs the price: rebuilding this is a project, not an evening.
Gioco editoriale: il verdetto dice se un agente può, l’indice se conviene.
What you build
Use an open noise-suppression model as a virtual microphone or post-process recordings before sending them to calls or files.
what you need
- audio DSP library
- OS-level virtual audio device
- model/runtime optimized for low latency
- macOS/Windows audio permissions
Interesting because AI model availability does not remove OS/audio-driver product complexity.
The prompt
A weekend with a coding agent. The gaps that stay are right below, under “what you lose”.
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.Prompt generated from the data on this page, not reviewed by hand yet. In English on purpose — it is the language coding agents work best in.
What you lose
- low-latency virtual microphone
- polished app switching
- model quality
- meeting integrations
- admin controls
Why people still pay
They pay because audio cleanup must be instant and invisible during real calls.
moat: Execution quality Proprietary models what a moat is
hardware/OS integration
Free alternatives
Not in the mood to build it? These already exist, they are free or open source, and we checked them one by one.
NVIDIA Broadcast free (si apre in una nuova scheda) — — one-click deploy Excellent noise removal, free in money and expensive in RTX silicon. Who has already built it
Starting from here is still vibecoding: the prompt is for when you want it exactly your way.
- RNNoise (opens in a new tab) — Open-source recurrent noise suppression model; useful but not a full Krisp replacement. (alive)
What it costs in a year
16 $/mese 192 $/anno
Listino 16 $ al mese a persona su Krisp. L’anno è dodici mesi pieni, senza sconti annuali.
