Sound Lock allows you to limit the volume of your playback by detecting the loudness and lowering it to the level you have set. So you no longer have to bother with the loud action scenes and sound volume going through the roof.
Sound Lock adjusts the system volume per channel (up to 14 channels) and generates a smooth sound output by lowering the volume during loud scenes. It therefore enables you to watch movies without having to adjust the volume manually every time it increases over the level of your comfort.
The application allows you to easily set the sound output limit by dragging the bar to the desired level.
