ABSTRACT:
A broadcast digital sound processing system includes an ISA (Industry Standard Architecture) bus compatible personal computer with a hard disk drove and a sound processor board installed in an expansion slot of the computer. The board includes a stereo input, analog to digital converter (ADC) and a stereo set of digital to analog converters (DAC's) interfaced to a digital signal processor (DSP) chip. A stereophonic audio signal is converted to digital data by the ADC and communicated to the computer by the DSP chip through a two port record first-in/first-out (FIFO) buffer for storage on the disk. A program is played back by communicating a program data file through a two port playback FIFO buffer to the DSP and from there to the DAC's for reconstruction to a stereo set of analog signals. The reconstructed audio signals may then be used as a modulating signal for radio broadcasting.
