Covers the use of certain preferred sampling frequencies in applications where there is a need for interchange of high fidelity digital audio programs with a minimum of transcoding complexity. Applications where such interchange may occur include, but are not limited to, master tape recordings (audio alone, and audio with video), submaster tape recordings prepared for transfer to a consumer product format, studio signal processing, and the point-to-point transmission of broadcast signals over satellite or terrestrial networks. This standard does not cover sampling frequencies for narrow band audio applications, such as voice-quality transmission links, or processing devices in which both the input and output signals are in an analog format, even if such signals are ultimately used for interchange of program.
