Summary

NoiseTorch-ng is a free, open-source Linux application that reduces microphone noise in real time. It uses RNNoise and works with PulseAudio or PipeWire, creating a virtual device named “Filtered Microphone” that other applications can use. The project describes setup as a two-click process, and distributes the application as a small, self-contained statically linked binary. OBS, Mumble, and Discord are among the applications where users can select the filtered microphone. The Voice Activation Threshold can be set as high as 95%, or to 0% to reduce noise without switching the microphone off. An optional virtual “Filtered Headphones” output lets users route application audio through output filtering. Microphone filtering adds 10 ms of inherent latency; output filtering is approximately 100 ms with PulseAudio. The project reports a suspected breach involving its update server and repository, says it found no malicious code, and says updates come from GitHub releases. GitHub lists no SECURITY.md file or published security advisories. Troubleshooting instructions, including how to collect debug logs, are in the project wiki.

Who it is for

It suits Linux users who want real-time microphone noise reduction in applications such as OBS, Mumble, or Discord. Users of PulseAudio or PipeWire can choose between those supported audio systems.

What is good

Free and open source
Supports PulseAudio and PipeWire
Creates a virtual filtered microphone
Voice threshold is adjustable up to 95%
Wiki includes troubleshooting and debug-log guidance

What to know first

Linux only
Microphone filtering adds 10 ms latency
PulseAudio output filtering is approximately 100 ms
Repository has no SECURITY.md or published advisories

Verdict

NoiseTorch-ng offers microphone filtering for Linux with virtual audio devices and adjustable voice threshold settings. Readers should weigh the listed filtering latency and the project's reported suspected breach when considering it.
