One for later today;I have a number of mpeg4's without audio tracks,and wish to extract audio from others to add to the soundless ones.
Programs available are virtualdub and audacity,can someone please advise if it's possible to do what's required,if so how?
A "walkthrough"of using audacity to do it will be greatly appreciated.
Many Thanks in advance.
