A new feature I was introduced to this week. Yes, they sort of sound like chipmunks, but your brain can get more information in the same unit of time. And why not?
Yes. Well it depends on the podcast. If the podcast has good speakers I can listen at 2x. Example is Security Now with Steve Gibson. Others I listen to between 1.25x-1.50x like What drives us and the Priuschat show. I love VLC!!! Its saved me days if not weeks of time by time compressing audio and videos.
