In Europe, EBU’s P / LOUD audio loudness problem group also is working to develop a new EBU recommendations. EBU practice guidelines in a number of fundamental principles and practices similar to ATSC A/85 recommendations. About audio loudness of the various testing methods have been in China and Japan, to develop practical recommendations to local audio loudness. Tektronix accordance with the above specifications and guidelines for developing a new type of audio loudness measurement hardware | tools, providing easy to program producers, broadcasters and other operators to understand the audio loudness measurement method.
