## What it is
NoiseTorch-ng is a Linux application that creates a virtual microphone with real-time noise suppression using RNNoise, working with PulseAudio or PipeWire. It ships as a small, statically linked binary with a simple GUI for two-click setup.

## Use cases
- suppress keyboard and fan noise on my microphone during calls
- remove background noise for Discord or Mumble voice chat
- create a filtered virtual microphone for OBS streaming
- clean up mic audio for video conferencing on Linux
- real-time noise suppression with PipeWire

## When to choose
- you're on Linux with PulseAudio or PipeWire and need real-time mic denoising
- you want a simple, self-contained tool that works with any VOIP app
- you prefer an easy GUI setup over configuring filter chains manually

## When to avoid
- you're on Windows or macOS
- you need noise suppression for recorded audio files rather than live input
- you need advanced audio routing beyond a single filtered virtual microphone
