"NoiseTorch is an easy to use open source application for Linux with PulseAudio or PipeWire. It creates a virtual microphone that suppresses noise, in any application. Use whichever conferencing or VOIP application you like and simply select the NoiseTorch Virtual Microphone as input to torch the sound of your mechanical keyboard, computer fans, trains and the likes."
In the new version 0.12.0 they completed a review of the code, and no issue was found. To help against any future issues, they're no longer using a separate update server and instead they will be using GitHub releases so it's all more transparent. For added security, they're also now using more GitHub features to validate the code too.
On top of that the new release also has some code cleanups, and the actual filtering status will be clearer now so it should give a better user experience.
