Overview: Worldwide, broadcasters are looking for practical approaches to digital audio production and delivery. One of the main dilemmas is to assess and control loudness with precision but without latency. Concerns include the added production time predicted with some suggestions of pre-transmission loudness measurements and format control. More TV channels with the same amount of viewers is not an indication to employ extra time in production. In this paper, new real-time approaches to securing loudness consistency, speech intelligibility, audio quality and format control are described. Experience from broadcast stations will be reported, including strategies for optimizing perceptually data-reduced audio, and targeting it for specific groups of listeners.
