Fixing GoPro Hero 3+ Audio 2019-10-16 02:16:58 I found some videos taken from 6 years ago of my now-deceased mother and my little children (not so little anymore). They were taken with a borrowed (and little-understood) GoPro Hero 3+. I did not mess with any settings.For some reason, the audio is not good. There are two problems. For some of the videos, the volume is just very low. Even increasing volume to the maximum on the computer watching the videos doesn't raise the volume enough to make them intelligible.For others, the same problem (perhaps a bit more amplitude), but there is a hum. Don't know why. Was always just powered by the battery.This is irreplaceable video for me. Do you have any suggestions for a software program that can manipulate these files to fix them? Each video has an associated MP4, LRV, and THM file.Thanks.
