Sonexis – Visual drag-and-drop audio effects for macOS system sound

Summary: Sonexis is a free macOS app that applies real-time audio effects to all system sound using visual effect chains. Users drag and connect effect blocks on a canvas to process live audio from any app, with immediate output through speakers or headphones.

What it does

Sonexis processes system audio by chaining or splitting effects visually, supporting independent left/right channel chains and 19 built-in effects plus AU plugin import. It manages audio routing internally and requires only the BlackHole virtual audio driver, which it installs automatically.

Who it's for

It is designed for macOS users who want to customize and enhance all computer audio, including music, video, and calls, with flexible effect chains.

Why it matters

Sonexis enables real-time, system-wide audio processing without complex setup, allowing users to shape their sound across any application instantly.
