Auto Volume Controller For Windows

1. Auto Levelling Check Box -> Enables/Disables automatic levelling of master volume for the system.
   
2. Volume Drop Speed -> The speed at which the volume is decreased when it exceeds the desired level.
   
3. Volume Rise Speed -> The speed at which the volume is increased when it goes below the desired level.
   
4. Current Volume Level -> Shows the current system volume. Dragging this TrackBar also allows the volume to be changed manually (difficult to do at runtime).
   
5. Tolerance -> Tolerance determines how much unit of sound the software allows to fluctuate from the desired level, before trying to adjust the volume.
   
6. Restore Volume Level on Exit -> When the application exits (through the tray icon), it sets the system volume back to the level it was before the application started.
   
7. Maintain Master Sound Level -> This is the main setting which sets the desired sound output level.
   
8. Display Refresh Speed -> To reduce the CPU usage, the refresh frequency for the progress bar can be reduced. Minimizing the Window to the tray also helps.
   
9. Levelling Frequency -> Determines how often the Levelling operation takes place. Lower value reduces CPU usage.

... When there's no download available.

 Oh, yeah ... Also hard to check with a ten-minute time limit.  I realize your wish to profit from this tool, but a fair trial is in order to determine suitability to need/task.

 For instance, I encounter a lot of Web pages with auto-starting audio/video (a/v), but seldom know when that will happen.  Since that's the reason I'm looking at the product, a ten-minute test interval is totally inadequate.

However, the same thing would apply if I were listening to CDs ... Make that interval a few days to a week in order to evaluate suitability - still a very short time frame, but ten minutes just won't cut it.
