Abstract
Method and apparatus for interfacing audio equipment and a computer system. Compressed parallel digital audio data originating on a system bus associated with the computer system is transmitted to a first data interface where the compressed parallel digital audio data is converted into compressed serial digital audio data. The compressed serial digital audio data is then transmitted to a second data interface associated with a digital signal processor. The second data interface routes the compressed serial digital audio data from the first data interface to the digital signal processor where the data is expanded and then returned to the second data interface. The second data interface then routes the processed serial digital audio data to a digital-to-analog converter where the processed serial digital audio data is converted to analog audio data and transmitted to the audio equipment for output. Analog audio data produced by the audio equipment is transmitted to a analog-to-digital converter for conversion into serial digital data. The analog-to-digital converter then transmits the serial digital audio data to the second data interface which routes the data to the digital signal p…
