How to increase sound volume

I need to turn up the audio in a video that is too low. I can hardly hear it clearly. Should I re-record it to a new file or need some software, tip or trick that can increase sound volume? I am urgent to improve it because I have a family party in the evening tomorrow. Thanks.
