I listen to podcasts on my iPhone at 2x and I was looking to emulate that functionality on iTunes. This app works for that purpose …. errr…. kinda. A few things I have noticed: First, when I am listening at a faster speed, it almost sounds like the audio is playing twice in very quick succession. It is not smooth the way that things sound on iOS. Second, if I start opening settings dialogues (or whatever) in iTunes while I’m listening then the audio will keep skippng back by a few seconds for no reason.
I say two starts because at the end of the day, the app works … but just barely.
