How do I increase the audio volume on a video I have a .wmv file where the audio volume is too low.  I was able to edit two files into one and match the volume of two video files to the same volume using windows live movie maker, but not to increase the volume, the (edit as opposed to the playback) volume control is max'd out, I can go down in volume but not up.  Can Blender help me increase the playback volume of this video?
You can increase the volume in the strip properties (select the audio and press N)



You can even go past eleven all the way to 100.
