We have recently been playing with the Free Trial version of Wavepad, and having great fun with creating music mixes. Question: 1. The audio sound is muffled and distorted, is this because of the trial version? Does this correct after purchase? 2. If purchased, am I able to save projects to mp3? or even itunes? We have also done some playing with MixPad Trial. It only saves projects with a (.mpdp). Does this provide mp3 options after license purchase? Any help is greatly appreciated.
