Headphones a little off? Noticing your audio isn't quite centred? Enter Balance Lock - it will keep your audio centred and prevent left/right drift.

It's the perfect utility for making sure when plugging and unplugging headphones that the audio stays centred. It was designed out of frustration of the long standing OS X bug where the audio balance can randomly move away from the center.

It's simple to use and runs in the background un-intrusively.

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

It runs in the background and wakes up only when the audio balance changes. So there's no excessive CPU usage or slow downs.
