- Abstract
- This paper describes an objective measurement system based on noise-to-mask ratio principles, designed and built at Canadian Broadcasting Corp. (CBC) Corporate Engineering, to test audio quality in radio and TV productions and networks that employ full or bit-rate-reduced digital and analog audio links. During the course of its development, this measurement system evolved to the point where it is now capable of being used in testing equipment and systems for the purpose of evaluation, acceptance, and maintenance. It has also been found useful as a production tool for signal-processing control.

bio
Marvin Nolan currently holds the position of supervisor, production support, Broadcast Engineering Services, CBC Engineering, Montreal, Que., Canada. He joined the CBC in 1988 as senior technical officer in the strategic engineering department of Engineering Headquarters. Since that time he has worked in a number of areas, including research and development, manufacturing, technology evaluation, business planning, system design, and international standards development. Nolan is an active member of a number of SMPTE Working Groups; most currently he is involved in the V.16 technology group.Robert TremblayCBC Engineeringbio
Robert Tremblay graduated from Laval University (Canada) with a degree in electrical engineering and began working at CBC Engineering in 1981. For several years he was involved in the development of various standards and practices related to the introduction of digital technologies into the CBC Broadcast Centre in Toronto. Since 1991, he has been engaged in the development of test methods for magnetic media, equipment evaluation, and compressed audio objective testing; he recently became involved in the development of objective test methods for compressed video signals. Tremblay is a member of IEEE's Broadcast Technology, Antennas and Propagation, and Electromagnetic Compatibility Committees. - Copyright
