Do you know the feeling of something interesting when the plot of the movie that you are watching, relaxing at home Scene dialogue Character X with the character Y is replaced instantly burst / shootout / any other event? And everything would be fine if not for the sudden volume jumps that are felt even more strongly in those moments when his ears trying to catch almost whispering voice of the speaker, and in the next moment is already compressed by the noise of broken someone's head on the toilet (remember the beginning of the movie «Casino Royale »). A similar game with the volume works well in theaters, adding to your viewing experience, but the same effect is severely hampered when you watch a movie at home, and the child / wife is sleeping in the next room.
Make the sound volume for the movie can be more uniform by compressing the dynamic range settings. If your player can not change these settings, you can just try to install another player, for example, XBMC, VLC or any other player with the presence of such functionality.
Consider the example of setting the compression VLC. You must go to "Tools" and select "Effects and filters." You can just press «Ctrl + E».
In the window that appears, go to the tab "Sound Effects," which, in turn, open the tab "Compression". Put a check thereby activating the compression, and then proceed to configure each of the parameters. Below is a pretty optimal setting, but you can always experiment yourself by achieving optimum sound for you.
To return the sound settings to the original enough to remove the check mark from the inclusion of compression. Enjoy watching.
