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.
