I have been sent a video clip from our latest gig, but it was taken on a small camcorder and the bass has overloaded the sound. Luckily I have a studio version at the same speed that I can use.
I don't have budget to use one of the packages I usually recommend, so can I do this on a Windows platform using only free/open source software?
Update (I should have included this earlier) - the audio is not the same length as the video, and it does not start in sync.
I have looked at Yamb but it really only works if everything is synchronised before you start.
(Have seen this question, but it doesn't help)
