Pro-Level Zoom Audio with Audio Hijack and BlackHole

During the pandemic, a friend sought a way to improve Zoom call audio quality. This post details the author's solution using Audio Hijack (instead of Reaper), the BlackHole virtual audio driver, and a DAW. By creating an aggregate audio device and cleverly using BlackHole's dual-channel capability (one for Zoom mic, one for speaker), and routing/mixing audio within the DAW, high-quality audio input/output is achieved, with monitoring, recording, and system sound sharing capabilities. This method bypasses Zoom's audio processing limitations, giving users complete control over their audio.
