The TeamTalk 4 SDK enables software developers to easily implement features for sending and receiving multiple audio and video streams over the Internet. The SDK consists of a client DLL and a standalone server which can be used in both LAN and WAN environments. It comes with wrapper classes for .NET Framework and a C-API which allows development on both Windows and Linux.
