Version 1.1 - May 15, 2021

Release Notes | EULA

Completely free with no purchases necessary and no ads
Requires macOS 10.12 or newer on Intel, and macOS 11.0 on Apple Silicon.

Noticing that the audio balance for your headphones is going slightly to the left or right? Balance Lock was designed to solve this by keeping the audio centred either in the middle or to a custom lock point. No more annoying left/right audio drift!

It runs unintrusively in the background, monitoring the audio levels to ensure that when plugging and unplugging headphones, the audio stays centered. It even has special support for USB audio devices so ensure all types of headphones are supported.

There's no cost for Balance Lock. No purchase, no in-app purchase and no ads. We wanted to make a simple to use utility that was useful to the Mac community at large, for everyone to use.

It's compatible with both Intel and Apple Silicon architectures so it's ready for all current and future Mac models.

No More Drifting

Balance Lock will keep the audio balanced in the middle (or a custom point) so you don't have to worry about checking the System Preferences every time you plug or unplug your headphones.

The dreaded balance drifting bug in macOS is now a thing of the past.

Helps Hearing Impaired

At people's request, we've added in the ability to set the lock point on a left-right slider. Instead of locking the balance to the center, it can be customized to either side or anything in-between.

This is a handy feature for those who are hearing impaired and want the sounds to only be available in one ear.

Get Notified

Get an optional notification when Balance Lock restores the audio balance after detecting that it has drifted to the left or right.

In addition, it also shows the last time and device that was fixed in the drop down menu.

Fully Optimized

Balance Lock is a Universal App, so it's built natively for all architectures. Whether it's running on an Intel or Apple Silicon chip, it's fully optimized.

This translates into a near zero CPU usage while it runs in the background waiting to fix any balance issues.
