OmniTek OTR 1001 User Guide, v3.1a K-15
The History displays can be restarted at any time by taking the Clear option that is included both
in the Button Bar and in the Properties display. The Button Bar also offers a Pause option which
pauses both the Loudness History display and the calculation of the Integrated Loudness until the
Pause option is selected again.
Note: The Integrated Loudness, maximum Short-term Loudness and maximum Loudness Range
may be reset from the Loudness View display described above.
Loudness History Trace
The graph of Loudness History comprises a solid coloured section showing Short-term Loudness
values going back over some defined period (chosen by the user), overlaid with a trace of the
Momentary Loudness measured over the same period. The right-hand end of the graphs shows
the values from the current frame. The calculated Integrated Loudness value is shown at the top
of the screen.
As in other Loudness displays, the Short-term Loudness graph is coloured from blue (too quiet)
to red (too loud) with green at the target level (set on the Audio Config page of the Config
window and shown in the title of the display).
Details of the audio input and the channel pair that is being analysed are shown at the top of the
graph (together with the Target Loudness). The period for which values are displayed is shown
in the top left corner of the display.

Loudness History Histogram
The alternative version of the Loudness History display comprises a histogram showing the
spread of Short-term Loudness and Momentary Loudness values over the same period, together
with the calculated Integrated Loudness value.
Details of the audio input, the channel pair being analysed and the period for which data is being
displayed are shown above the histogram as described above for the Loudness History Graph.
