Sotto removes background noise from your microphone in any macOS call app — Zoom, Google Meet, Teams, Discord, OBS. It runs DeepFilterNet3 entirely on your device, ships its own audio driver (no virtual cables), and needs no account or cloud. Free and open source (MIT). A no-subscription alternative to Krisp's core feature.

Partial The noise-suppression model (DeepFilterNet3) is open source, but the virtual audio driver and real-time low-latency routing on macOS require low-level Core Audio and driver/signing expertise that vibe coding handles poorly.
What it would actually take: The app needs a macOS audio driver (historically an AudioServerPlugIn or DriverKit extension) that exposes a virtual microphone, plus a real-time audio pipeline that feeds samples through the DeepFilterNet3 model via ONNX or Core ML. Building it requires Core Audio internals, real-time thread safety, code signing and notarization, and debugging latency and driver crashes. A solo developer with systems audio experience could do it, but it is far from a prompt-only build.
