Microsoft has released a small whitepaper to the public detailing the some of the features of RTAudio -
The document provides a functional description of the Microsoft RTAudio speech encoder and decoder. A list of core capabilities is provided. Also, a detailed list of features such as rate control and forward error correction is included to show how the codec can be used in Voice over IP and other IP Ntwork-based media communication solutions. Finally, the document includes information for licensing this technology from Microsoft Corporation.
As part of the MVP programme and the OCS Voice TAP I have been delving quite a bit into RTAudio and RTVideo (As preparation for delivering Unified Communications Bootcamps to the largest Microsoft partners in Europe) and there are some really interesting inventions and advancements that I hopefully can talk more about as OCS comes closer to its release date.
