Hey Product Hunt 👋

I built mactooloud because of one specific moment that kept happening:

a Zoom call starts while Spotify is at 100%, and I'm scrambling to find

the tab, find the app, turn it down — then forgetting to turn it back up.

macOS gives you exactly one volume slider for your entire Mac. That felt

like an oversight worth fixing.

mactooloud is a menu-bar app that gives every running app its own slider,

plus a few things I now use daily:

🎚 Auto-Duck — the second Zoom, Slack or Discord touches the mic, music

fades to 10% and comes back when you hang up

🔎 Mystery Sound Finder — a live list of every app touching your speakers,

including the one hiding in another Space

⏱ Focus blocks — a pomodoro that mutes everything except the one app you

want playing

💼 Profiles — save a mix and bind it to a macOS Focus mode

One technical note I'm proud of: it uses the CoreAudio Process Tap API

Apple shipped in macOS 14.4, so there's no audio driver, no kernel

extension and no virtual output device to install. Most per-app audio

tools on macOS have historically needed one. The tradeoff is it requires

macOS 14.4 or later. Universal binary, Apple Silicon and Intel.

Pricing: 7-day free trial, no card. Then $4.99/mo, $39/yr, or $90 once

for a lifetime licence on one Mac.

The thing I'd most like feedback on is the Auto-Duck tuning — I landed on

10% volume, a 175ms fade and a 1.5s restore delay, but that's calibrated

against my own setup and my own meetings. If it feels wrong on yours I

want to know.

Happy to answer anything in the comments 🙏
