ballast for Mac

Keep your Mac’s sound consistent

Ballast is a free macOS utility that lives in the menu bar and helps keep audio levels steady across different applications. It prevents volume drifting so your listening experience stays uniform, whether you’re watching videos, mixing audio, or joining calls.

How it works

The app runs quietly in the background and continuously monitors output levels. When it detects changes that would make audio inconsistent, it automatically nudges levels back to the chosen balance. A compact, user-friendly interface makes it simple to view current settings and make manual adjustments when needed.

Who should use Ballast
