Could you please give me an advice concerning the following problem ?
I have a videoclip with good image but the sound is horrible.
What I would like to do is replace the videoclip bad sound (mp3) with the same good sound (mp3 too) that I got elsewhere on my hard drive (in an audio files folder)
Unfortunately there is a “time stretching” and “lip-sync” isssue, because :
- The mp3 included in the videoclip is 3 min 3sec length
- The mp3 I would like to use is 3 min 0sec length
So is there an easy way to “time stretch” my external mp3, changing its lenght from 3’0’’ to 3’3’’ , it shouldn’t be a problem if the “pitch” changes (it shouldn’t be noticeable because it’s 3 sec compared to 3 min)
Could Audacity do this ? Or maybe another easy program to use ?
Many thanks in advance
