About

NoiseTorch-ng is a free, open-source Linux application that suppresses microphone noise in real time using RNNoise. It supports PulseAudio and PipeWire, and creates a virtual microphone called “Filtered Microphone” for other applications to select. The project describes the setup as a two-click process and distributes the application as a small, statically linked, self-contained binary. OBS, Mumble and Discord are named as applications where the filtered microphone can be used. Its Voice Activation Threshold can be set as high as 95%, or to 0% to dampen noise without deactivating the microphone. An optional “Filtered Headphones” virtual output lets applications be routed through output filtering. Microphone filtering introduces 10 ms of inherent latency; output filtering is approximately 100 ms with PulseAudio. The project reports a suspected update-server and repository breach, says no malicious code was found, and says updates are retrieved from GitHub releases. GitHub lists no SECURITY.md file and no published security advisories. Troubleshooting guidance, including instructions for collecting debug logs, is in the project wiki.

Who it is for

NoiseTorch-ng suits Linux users who want real-time microphone noise reduction with PulseAudio or PipeWire. It may also fit users who want filtered microphone input available to applications such as OBS, Mumble or Discord.

What is good

  • Uses RNNoise for real-time noise suppression.
  • Supports PulseAudio and PipeWire.
  • Creates a virtual filtered microphone.
  • Threshold can be set to 0% or 95%.
  • Free and open-source.

What to know first

  • Microphone filtering introduces 10 ms latency.
  • PulseAudio output filtering is approximately 100 ms.
  • No SECURITY.md file or published advisories are listed.
  • Project reports a suspected update-server and repository breach.

Verdict

NoiseTorch-ng offers Linux microphone filtering through a virtual device, with optional output filtering and a configurable voice threshold. Consider its listed latency and the project’s reported security incident before choosing it.
