  1. I couldn’t stand the slowness of voice, especially when I was watching the YouTube videos. There’s no speed controller for me to fast forward, what’s so lucky for me that I found this article, and right now I am watching the videos with 2.0X speed, everything seems perfect right now. I don’t need to bear with the slower voice gain. LOL
