The unique high resolution circular Loudness visualization:
Watch the loudness course on a radar screen
The Radar instrument, developed by TC Electronic, is a high-resolution display of momentary loudness and loudness history in a single, unique Radar view. The circular, color-coded display makes it easy to balance audio visually and to see when level falls below or exceeds the end-listener's loudness range tolerance.
The moving outer ring of the instrument represents the Momentary loudness value changing its color when passing the Target Level. The area inside of this ring showing concentric circles is called Radar view and represents the Shortterm loudness history (1 minute to 24 hours). The thicker circle represents the Target Level, its outer part shows exceedings, the inner part shortfalls.
It is a tremendous help for a mixing engineer or a video editor to know which radar area to stay inside. For example, film sound may fall outside the normal broadcast expectations.
The radar is complemented by a true-peak warning and by two descriptors to characterize the entire loudness ‘landscape’ of a program, film or music track precisely. By default, the numbers displayed are program loudness and loudness range.
|Mode:||Radar or Statistics|
|Sliding Loudness:||3 s, 6 s, 10 s, 15 s, 30 s, 1 min, 2 min, 4 min, 8 min|
|Descriptors:||Off, Program Loudness, Loudness Max, Loudness Range, Sliding Loudness (max. 2 at a time)|
|Speed:||1 min, 4 min, 12 min, 30 min, 1 h, 2 h, 4 h, 12 h, 24 h|
|Resolution:||3 dB, 4 dB, 6 dB, 8 dB, 10 dB, 12 dB, selectable|
|Low Level:||-30 to -6 LU|
The example shows the Radar with a relative LU scale and the Target Level at 0 LU (12 o'clock position).

The Radar instrument displays momentary loudness and loudness history in a circular, color-coded display acc. to the selected Loudness standard.
It makes it easy to detect loudness of audio signals and adapt them to a requested target or to other delivery standards.
The moving outer bleu-green circular bended bargraph displays the current Momentary loudness value, changing to yellow-orange when passing the Target Level (12 o'clock position). Also a Low Level Below value can be adjusted to define the changing from green to blue and which might not be undercutted.
The Radar View, the area with the concentric circles, shows the Short Term loudness history (1 min. to 24 hours). Its thicker light blue circle represents the Target Level of the selected loudness standard. Exceeding values will be displayed in the section outside this circle (Loud Part) and values falling below in the inner section (Soft Part). The turning needle shows the current value.
Both optical displays are complemented by a true-peak warning and by two descriptors.
Each descriptor can show one of four options:
The difference in loudness (resolution) between the circles in the Radar View can be adjusted. Choose low numbers when targeting a platform with a low dynamic range tolerance. It is a tremendous help for a mixing engineer or a video editor to know which radar area to stay inside. For example, film sound may fall outside the normal broadcast expectations.
