Unboom is a focused macOS menu bar utility for people whose monitors sound boomy because of their room. A short microphone-assisted scan finds the resonance, and a peak-only correction cuts just that frequency from all Mac audio. The marketing site at unboom.app ships a free browser-based Boom Finder alongside it.
The problem
Correcting every app's audio on macOS without a kernel driver, while guaranteeing the Mac never goes silent or clicks if the correction stalls or crashes — and making room acoustics understandable to people who have never seen a frequency response.
What I built
Built on Apple's Core Audio process-tap API (macOS 14.2+) with a lock-free AUHAL bridge to the physical output, a cut-only PCM correction core with click-free bypass, and fail-safe dry-path recovery. The UI hides the numbers: a safe level check, an automatic room scan, and a "That's the boom" button as a listening-only fallback.
