Speaker Locker is a system utility for Windows which allows you to automate system volume changes throughout the day.
Up to 5 periods of a day, in various different lengths, can be programmed to have different volume settings applied to them automatically. So, for example, if you need your computer muted automatically when you’re out of the house, or just turn down volume when the neighbors are sleeping, just program that setting in Speaker Locker and leave it running to do its thing.
The 5 spots for setting up periods of the day when you want to automatically change system volume can be seen right from the top of interface. Not all of them have to be activated. You can use the Enable check mark at the start of each one to turn on the ones you need.
Various other switches and options are available at the bottom and on the right. Out of all these, the one that stands out the most would be the fact that you can password protect Speaker Locker, so that when it’s accessed from the system tray you need to provide a password.
