VolumeBoost Audio

VolumeBoost Audio is a lightweight macOS menu bar app for making quiet audio louder across apps, browsers, and videos.

Open VolumeBoost from the menu bar, set the boost level, and start boosting when audio is too quiet. Smart Boost helps quiet sources feel more consistent, while the Soft Limiter smooths loud peaks so high boost levels stay cleaner.

VolumeBoost processes audio locally on your Mac. It does not upload audio and does not include third-party analytics or advertising SDKs.
