Method and system for decoding digital audio files

A system (99) and a method decodes digital audio data (126) by identifying circuits (112) on peripheral devices (119) attached to a computer (113) or peripheral interfaces (107), such circuits capable of performing digital to analog conversions, and sending to these circuits during an interrupt (133...

Zusammenfassung:A system (99) and a method decodes digital audio data (126) by identifying circuits (112) on peripheral devices (119) attached to a computer (113) or peripheral interfaces (107), such circuits capable of performing digital to analog conversions, and sending to these circuits during an interrupt (133), digital audio data (126) for conversion to analog form (128) and outputting to conventional audio stages (139, 141). Because the system and method employs existing circuitry to perform the digital decoding they do not require the use of additional processing hardware to be implemented solely for the decoding process.
