Mac users interested in Audio sync fixer generally download:
SubFix is a utility that lets you fix the timing in a subtitle file. It has happened to me many times that I download a subtitle and it is out of sync with a video file. Most applications that can be used to adjust your subtitle's synchronization require you to adjust every line of a text, and this can be very time-consuming, especially if your video file is long.
