Overview
Krisp
Krisp is an AI productivity layer that sits between your microphone/speaker and your communication apps to eliminate distracting background noise. You can use it to remove barking dogs, crying babies, or keyboard clicks from your calls in real-time. It works bi-directionally, meaning you can cancel noise coming from your own environment and also mute the noise coming from other participants on the call.
Beyond noise cancellation, you can automatically record and transcribe your meetings with AI-generated summaries and action items. It integrates with over 800 apps, including Zoom, Microsoft Teams, and Google Meet, without requiring any special hardware. Whether you are a remote freelancer or part of a large enterprise call center, you can maintain professional audio quality regardless of your physical surroundings.
NoiseGator
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. It is a straightforward solution for anyone needing a professional audio bypass without investing in expensive hardware processors.
