What balance actually changes
Every stereo device in Windows has a volume for the left channel and one for the right. Balance is the difference between them. Windows does have a balance control, but it sits several pages deep in Sound settings and has to be found again every time.
Modern Audio Balancer turns the quieter side down and leaves the louder side where it is. Your overall volume does not change, and moving the slider back to the middle puts both sides exactly where they started.
On a 5.1 or 7.1 device it balances the front left and right speakers and leaves the rest alone. A device with only one channel cannot be balanced, and the panel says so by name instead of quietly doing nothing.
How to change left and right audio balance in Windows
Modern Audio Balancer keeps the balance slider one click from the clock. You can adjust it, check it and close it in a few seconds.
- Click the Modern Audio Balancer icon in the notification area. The panel opens beside it, wherever your taskbar is docked.
- Move the slider toward the side that needs more. It moves one percent at a time.
- Read the line under the slider, such as "20% left", to see exactly where you are.
- Press the button under the slider to put both channels back to center.
- Click anywhere else to close the panel, or right-click the tray icon for left, center and right without opening it.
Balancing audio for one ear or one headphone
If you hear less on one side, or one side of a pair of headphones has worn, a balance you can read in words is easier to live with than one you set by eye. The panel says "Centered" or how far to which side, so you can return to a setting that worked, and a percent at a time lets you make small corrections.
Because only the quieter side is turned down, shifting the balance never lowers your overall volume. In settings you can pin the balance to one output, your headphones for example, and leave Windows playing through your speakers, or the other way round.
How it differs from the balance setting built into Windows
Windows keeps its balance control inside Sound settings, several pages in. Modern Audio Balancer puts the same left and right channel volumes in a flyout from the tray, and the tray menu reaches left, center and right without opening anything at all.
It also shows what the sound is doing, not just where the slider is. Each channel has a live level bar in Smooth, Segments or LED blocks style, so you can watch one side get quieter as you move it. While the flyout is closed it does no audio work at all, and it stays out of your taskbar and Alt+Tab.
