If used for lecture play-back...

This app does what it says it will and it does it effectively. That said, I downloaded this to speed up the play-back of my biochem lectures so I wouldn’t have to sit for an entire hour to re-listen to an entire lecture. However, anything faster than 1.75x is choppy and 2x+ is nearly indistinguishable/inaduible. Again, it works perfectly and effectively but just know that there are limits to its power. I really like that the pictch of the professor doesn’t change with speed increase or decrease (I was worried about havign to listen to Alvin and the Chipmunks at increased speeds). I have also played with my music using this app and have been pleasantly amused with the results… of course the humor I find in messing with my music could be the 2am studying binge speaking...

Works … just barely

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.


Simply put it does ABSOLUTLY NOTHING.

I've tried it on 5 different computers and it does NOT work on any of them.

*Update: I have since gotten this app to work with a audio book, but the wont do anything when it comes to podcasts. The Developer needs to remove his claims in regards to podcasts from the app description. I have tried this app while listening to dozens of podcasts and it does nothing with any of them.

The developer does respond to support requests, but cannot figure out why his own app does not work. From my corispondave I have learned that I have tested his app on more systems then has.
