Digital audio measurements for broadcasting

Transmitting and storing audio signals in the digital domain is well-established in the broadcast industry. Analog audio has given way to the AES3 and Sony/Phillips digital interface format (SPDIF). AES3 datastreams are also embedded in SDI television signals. The first part of the paper is describing the digital audio signal itself to get a better understanding of the related problems. The problem issues and solutions are presented next. A brief look on additional measurements is given.
