Vat is a software that allows for audio conferencing.
Vat is an audio conferencing application created by the Network Research Group of Lawrence Berkeley National Laboratory. It is a real-time, multi-party, multimedia application for audio conferencing via the Internet. The application is based on the Draft Internet Standard Real-time Transport Protocol (RTP) developed by the IETF Audio/Video Transport working group. The source code and pre-compiled binaries are available via anonymous ftp.
RTP is an application-level protocol implemented entirely within vat, so no special system enhancements are needed to run RTP. Vat can be run point-to-point using standard unicast IP addresses, but it is primarily intended as a multiparty conferencing application. To use the conferencing capabilities, your system must support IP Multicast and be connected to the IP Multicast Backbone (MBone).
Vat provides only the audio part of a multimedia conference, and other tools such as video, whiteboard, and session control tools are implemented separately. Vic is our video tool, wb is our whiteboard tool, and sdr is the session directory tool developed by UCL. Other related applications include ISI's Multimedia Conference Control, mmcc, the Xerox PARC Network Video tool, nv, and the INRIA Video-conferencing System, ivs.
This release of Vat includes several new features and bug fixes. For example, code has been added to the Windows audio driver to convert to 8-bit linear if the driver doesn't support 16-bit linear. Unicast sessions wouldn't work under Windows, so the fix from John Brezak that somehow got left out of b1 release has been incorporated. The vat 3.4 "[net localport]" command was restored, which is needed by ISI/MIT RSVP additions to vat, and a sitebox display bug on monochrome displays has been fixed. Additionally, bugs where SS-10 could get stuck sending a continuous tone if the last byte before a completely silent frame was non-zero, and where the URL of SCO port on the vat homepage was incorrect have been fixed. Lastly, this release includes Irix5.3 and 6.x configure and config.h fixes, and AIX configure and config.h fixes.
