Hey Product Hunt 👋

I built SOUND because of a small daily annoyance I couldn't stop noticing: my Mac has exactly one volume, and no equalizer at all. A podcast is boomy, a game is harsh, one browser tab is twice as loud as everything else — and the only lever macOS gives you is "turn it all down."

SOUND lives in the menu bar. Every app that's currently playing shows up with its own 8-band EQ (63 Hz to 8 kHz, ±12 dB), its own volume, and its own output device — so you can pin a call to your speakers while music keeps going to your headphones. There's a System master for everything you haven't touched, six presets to start from (Flat, Reduce Bass, Bass Boost, Vocal, Podcast, Bright), and one power toggle that puts every app back to untouched audio.

Two things I want to be upfront about:

It needs macOS 26. SOUND is built on the modern Core Audio process-tap API and the Liquid Glass design system. That's what makes it work with zero virtual audio drivers — no kernel extension, no fake output device, nothing to uninstall later. The cost is that older macOS versions can't run it.

It asks for system audio permission, once. That's the OS gate for reading an app's audio so it can be equalized. Nothing is recorded, stored, or uploaded • the processing happens locally, in real time, in the audio callback, and there's no account and no server to send anything to.

It's free, ships in 10 languages, and follows your system language. Install it from the Mac App Store: https://apps.apple.com/app/sound...

I'd love to know: which app on your Mac sounds wrong, and what would you do to it? That's mostly how I've decided what to build next.
