1-1, or a more detailed but still easy-to-read information, like the corridor chart in Fig. 1-2. This plot shows the target loudness area as a corridor, and reads over time. A more sophisticated way to read loudness, for example in master control, would be a numerical readout, which is controlled from the playout system. As shown in Fig. 2-1, the master control engineer can see the actual program loudness of a segment, plus a longterm program loudness, which includes all segments of a television show. There are also bar readouts, for those used to this kind of display, illustrating the loudness as seen in the center of fig. 2-1. Fig.3-1 For those engineers interested, and able to control the dynamics of a signal, a loudness range indication will be helpful. In the Fig 3-1, this is shown as a “magic eye” – wide bar � larger dynamic, spot � no dynamic at all; the combination of the magic eye, but tied with its center to the actual integrated reading. In combination with these types of display there are also various coloring modes, like three colored areas for “low, comfort, high” LRA or color swap of the complete bar. An informative Production Engineer display is shown in Fig. 4-1. It is the combination of a visualization of all the audio as it appears to the listener. The weighting of the signal is compliant to the loudness standard (red markers read channel target loudness). The bar and the numerical at side, as well as the LRA indicator, present a full picture of all necessary information. For mixing purposes, this type of display can be linked to timecode. Fig.4-1 Finally, Fig. 5-1 is a live loudness and loudness dynamic regulation program called Continuous Loudness Control. The graphical display gives experts all required information about actual audio loudness and dynamic range, as well as target values and regulation process data. Any of the figure mentioned above can be helpful for a range of audio engineers, from beginner and standard to expert levels. Choosing the program that best suits your needs is the first step in ensuring proper loudness control.
