Limiting the Sound Loudness Level

Sound Lock is a free audio application that limits the volume of the sound that comes out of your PC. When you want to watch movies or listen to music, but don’t want to manually adjust your volume during loud scenes, this software can help. It allows you to limit the volume of your playback by detecting the loudness and lowering it to the level you have set. With this, you can continue your streaming without breaking your eardrums.

How to use Sound Lock?

Sound Lock is an effective sound output level limiter for PCs. It is a lightweight application created to help users limit the sound level of all audio streams they play on their computers.

You can even pin the app on your taskbar.

Aside from setting the limit of the sound, you can also enable or disable the program’s setting directly from the taskbar. You only have to click the lock icon to launch the app. you can also select the filtering mode—either channel or master—and configure the parameters for the output channels and devices. This applies to headphones, speakers, or any default device.

It can automatically detect the volume of the utility you’re running in your computer and adjust it to your pre-defined setting.  It runs quietly on the background until you launch it to tweak the settings.

The app stays on top of the programs, no matter how many windows you open. It carries out its tasks quickly and without errors. More, it leaves minimal footprints on your system, so it does not affect the overall performance of your computer.
