The rapid development of computer technology has laid a solid foundation for the transformation of broadcasting technology from analog to digital. With the changes in radio broadcasting methods, broadcasting recording equipment, recording techniques, and recording techniques are also constantly being updated and improved. Especially the use of audio workstations. Making operations that were previously difficult to achieve with analog devices effortless. Excellent performance and full functionality. Digital products with good quality and high degree of automation have been launched one after another, and digital audio technology and equipment have replaced traditional analog audio technology and equipment. This standard specifies the technical requirements and measurement methods for digital audio recording systems in broadcasting centers. Any equivalent measurement method that can ensure the same measurement accuracy can also be used, and in case of dispute, this standard shall prevail. This standard is applicable to the design, measurement, maintenance, and acceptance of digital audio recording systems in broadcasting centers.
