Years ago I saw someone use a program for Windows and I was hoping that someone can tell me if there is a Mac equivalent!
Say you are watching a YouTube video and the audio is up full but it's still quiet. The audio on the video is out of sync too.
You open this program and you can increase the audio even though it's full on YouTube. You can also speed up the audio so that it is in sync with the video.
Is there an app available for OS X that allows me to do this?
