I use my iPod and Belkin TuneTalk to record class lectures for listening to later when studying for tests/finals. This works perfectly and I highly recommend it to anyone who may need to record lectures. My problem, however, is that I would like to speed up the playback to 2x faster so that I can listen to it quicker than the actual lecture was to save time. Is there a way to do this either in iTunes or on my iPod? I have a 3rd generation iPod nano (the short, fat one). Any help would be greatly appreciated.
