In addition to the improved tablet changes, Skype also added support for their audio codec, SILK. Which was designed to capture the richness of the natural human voice. It is designed to help deliver the best audio quality across all internet connection types to make sure your voice is heard loud and clear versus garbled and broken. Skype 3.0 also lets you sign in and merge with your Microsoft account for a more seamless experience.
