NoiseGator is a nimble, Java-based noise gate tool designed to clean up your audio feed by cutting out unwanted background hiss and hum. You can use it to suppress the sound of your keyboard clicking or your computer fans whirring while you are on a call or recording a podcast. It works by analyzing audio levels in real-time and muting the input when the volume drops below a threshold you define.
You can route your audio through virtual cables to integrate it with apps like Skype, Discord, or OBS. Because it is open-source and runs on Java, you can use it across Windows, Mac, and Linux systems without worrying about heavy resource consumption.
