## What it is
Cadmus is a Python GUI application that provides real-time microphone noise suppression on Linux by wrapping @werman's PulseAudio noise suppression plugin. It adds a tray icon to select a microphone and creates a denoised virtual PulseAudio input usable in any communication app.

## Use cases
- remove background noise from microphone on linux
- suppress typing noise in discord calls
- denoise mic for zoom or skype without command line
- create a virtual noise-cancelled microphone in pulseaudio
- real-time voice noise suppression gui

## When to choose
- you need a simple GUI for real-time mic noise suppression on Linux with PulseAudio

## When to avoid
- the project is deprecated - use NoiseTorch instead
- you use PipeWire rather than PulseAudio
- you need Windows or macOS support

## Facets
- artifact type: application
- maturity: abandoned
- function: audio-processing, gui
- domain: operating-systems, developer-tools
- platform: -
- tags: noise-suppression, pulseaudio, microphone, voice-calls, tray-icon, deprecated, audio, linux, desktop
