I replaced my brown-noise browser tab with a menu bar app

Rahul built Hush, a tiny Mac menu-bar app designed to remove the friction of keeping a focus noise running in a browser tab. After trying classical music and podcasts, he settled on generated noise - specifically brown noise for a deep rumble and a “speech blocker” tuned to mask human-voice frequencies. The problem Hush addresses is simple: switching to a noise tab distracts and leads to other distractions. Hush sits in the menu bar so right‑clicking toggles sound immediately, left‑clicking opens controls where users can choose brown or speech‑blocker, set volume, and adjust a low‑pass cutoff for the brown noise.

Hush generates both sounds in real time, runs fully offline, is CPU‑friendly, and is Apple‑notarized so it opens cleanly on macOS. Distribution is pay‑what‑you‑want with a $0 option and the source is available on GitHub under an MIT license. Beta testers shaped the feature set - white and pink noise were dropped after feedback that they were unused or harsh - and early public downloads have followed a small private beta. The pitch is practical: replace a persistent noise browser tab with a lightweight, instant-access tool that reduces context‑switching and helps maintain focus.
