QuietKit: macOS Noise Reduction Software

Open-source audio noise reduction for calls and recordings on macOS, suppressing ambient sounds in real-time.

What is QuietKit?

QuietKit is an open-source noise suppression application for macOS developed by Manila Sunset. It is designed to remove ambient background noise from audio input sources like microphones and internal sound cards.

The software works by analyzing the incoming audio stream in real time and applying noise reduction through a process called spectral subtraction. It detects repetitive noise patterns like fans, keyboard clicks, mouse clicks, etc. and selectively suppresses just those frequencies while leaving the rest of the audio untouched.

This allows QuietKit to clean up the incoming signal while introducing very little distortion. The result is much cleaner audio on calls, voice recordings, video calls, podcasts, and more. It works with any app that accepts microphone input.

As an open source project, QuietKit is completely free to use and the source code is available for transparency and community contributions. It runs natively on macOS systems with support for both Intel and Apple silicon Macs.

Overall, QuietKit is a specialized tool to capture high quality, low-noise audio by eliminating ambient sound from fans, HVAC systems, keyboards, and more. It excels at keeping speech and vocals clear while suppressing unwanted background noise.
