This paper reports on recent progress in digital audio technology, including improvements in analog-to-digital (A/D) and digital-to-analog (D/A) converters, magnetic-recording-head design, modulation schemes, error-correction schemes, and editing processes. The improvements are remarkable and have contributed greatly to cost reduction, better sound quality, reliable higher packing density, and increased versatility. Newly developed digital audio systems that include professional recorders, satellite broadcasting, and digital audio disks are described. Large-scale integrated (LSI) circuits developed for consumer systems and their impact on digital audio are also reviewed.
