Yes, I know that the best solution to this is to go back and re-record, but that's not an option. I've shared a Google Drive folder with a .WAV file extracted from video shot on a Nikon D5100. The microphone on the camera was obviously not able to handle the huge sound that the piano produced in such a small room.
I've tried a couple of things, but I'm at a loss. Help?
