DISPLAY AND METER OPTIONS
♦
Selecting the
Short Term Loudness Graph
provides a graphical representation of loudness over time.
Because it does take addition CPU resources to create the graphs, graphic is turned “off” by default and
must be enabled for each processing core (FM and HD) in the
Meter Options > Meter Options
menu.
♦
The
Source
dropdown menu determines the audio source feeding the graph. Available sources are
determined selections made in the
Meter Options > Meter Options
menu.
♦
By default, the graphs display data in
Relative Time,
that is, since the graph was first enabled. Checking
the
Local
control changes the display to the actual time as set in the
System > Time/Date
menu. Choosing
the
UTC
option reflects Coordinated Universal Time (no local time offset). When remotely connected
to Omnia.7 via the NfRemote software, an additional option called
Remote
is available which reflects
system time of the host PC.
♦
The
X Range
control determines how long a period of time is shown in a particular display window. The
most recent information will always be at the far right of the graph, but advancing this control will show
more historical data at once though in less detail.
The exact length of visible time - that is, how much historical data can be displayed - will be dependent
upon how much screen real estate is devoted to the graph. On smaller displays, or if multiple displays are
enabled at once, each display will get less screen space and as a result, less past data will be visible.
♦
The
History
control determines allows you to “travel back in time” anywhere from the present to 24
hours in the past. With the slider set to 0%, the most recent information is displayed. Advancing the
control looks further back in time.
♦
The Y
Zoom
control determines the visible range of loudness measurements on the LKFS/LUFS scale
on the left side of the graph. At its default setting of 1.0 X, levels from approximately -30dB to +6dB are
displayed. A wider range of levels can be seen by sliding this control to the left, while sliding the control to
the right narrows the range.
♦
The Y Center control determines which LKFS/LUFS value on the left scale appears centered on the
display. The default setting of 50% places the middle of the graph at -12dB.
