Today while editing a video, I realized one section of audio is extremely loud, while others are so soft you can hardly hear them.  While trying to figure out how to adjust this, I discovered, according to the preferences, that I do not have a sound editing program selected.
I've never used a sound editor before.  Can someone recommend one?  Or, is there one preinstalled with Vegas 6 that I just have not yet discovered?  Any feedback much appreciated.
