NoiseTorch

• Background noise from your mic, such as a mechanical keyboard, computer fans or trains (Filtered Microphone)
• Noise in the sound of apps you send to Filtered Headphones

• Linux only, with PulseAudio or PipeWire
• No new release since v0.12.2 on 17 June 2022, and the newest code change is from January 2025 (checked 2026-10-18); the project's README lists Easy Effects (PipeWire only) and noise-suppression-for-voice as alternatives
• The project now calls itself NoiseTorch-ng
• Adds about 10 ms of delay to your mic, and around 100 ms to output filtering with PulseAudio
• Its Voice Activation Threshold mutes the mic when it hears no voice; if you cut out while talking, lower it, then reload NoiseTorch-ng

NoiseTorch-ng → select your microphone → Load; then pick Filtered Microphone as the input in the chat app

After you switch, run the noise test with the NoiseTorch microphone selected in your browser's mic list, and compare the floor with your plain mic.
