I just finished a Skype call with Jim Courtney using the new Skype Beta 3.2. The sound quality is stunning. Using only the PC microphone and speakers, there was no echo, full duplex sound, and excellent quality audio. Moreover, the new codecs are super CPU efficient. Even while running Windows Update, and an Outlook email download, there was no discernable loss of quality.
I am gobsmacked. The biggest feature in Skype Beta 3.2 isn't payments or any of that other stuff. It's sound quality.
