Abstract: A stereo computer system with resources to produce and record surround sound channels. Such surround sound channels are played or recorded using an audio card added to the computer system, which audio card controls additional speakers and/or microphones. Software for redirecting instructions from existing stereo application programs and sending these instructions to the existing audio device driver and the additional audio device driver is provided. Resources for processing the digital audio data for either extracting surround sound channels from two channel data provided by the application, or for encoding two sets of two channel audio data recorded by the two audio cards is also included.

Abstract: A computer conferencing system permits individual workstations, capable of communication with other stations by means of telecommunication or network links of diverse types, to participate in a conference through a dynamic network which they may enter or leave at will. Each participating station must be able to establish at least one and preferably at least two independent physical communication links with other stations, and maintains a network routing table storing data as to other stations to which it is logically connected directly or indirectly through stations to which it is physically connected. on establishing a physical connection to another station it transmits data to that station based on the content of its routing table and receives data based on the content of the other station's routing table. It also transmits, to other stations to which it is logically connected, data relative to changes in its logical status, and receives data as to changes in the logical status of other stations within the network, and updates its routing table accordingly.
