You can select the style of peak hold when peaks are shown in the plug-in meters:
• 3 Sec Hold — Displays peak levels for 3 seconds.
• Inf Hold — Displays peak levels until meters are cleared.
• No Hold — Does not display peak levels.
You can also adjust the level of the reference mark on the side of the meter display by dragging
the reference mark to a different location on the meter scale.. The mark is set by default to the
reference level for the corresponding meter type.
n
Meters also change color to show different ranges of level. The relative range of color
automatically adjusts to follow the current Reference Mark setting in all meter types (except
Peak+RMS).
Meter Description
Peak (Default meter type) Uses the metering scale in DigiRack EQ III and Dynamics III plugins.
RMS (Root Mean Square) was used in previous versions of the Avid SurroundScope plugin and uses
the same “true” RMS metering scale.
n
The “true” RMS meter scale is not the same as the AES 17 RMS scale. For a sine wave
with a peak value of –20 dBFS, the “true” RMS meter will show a value of –23 dBFS.
(The same sine wave will show a value of –20 dBFS on an AES 17 RMS meter.‚
Peak + RMS Uses a multi-color display to show both types of metering. Peak metering is shown in
conventional green color, while RMS metering is shown in blue.
VU (Volume Unit) Uses AES standards for signal level indication.
BBC Uses IEC-IIa standards for signal level indication. This style of metering suppresses short
duration peaks that would not affect broadcast program material. Reference calibration (4 dB) is
–18 dBFS.
Nordic Uses IEC Type I standards for signal level indication and provides greater resolution for readings
between –10 dBu and +4 dBu. Reference calibration (0 dB) is –18 dBFS.
DIN Uses IEC Type I standards for signal level indication and provides greater resolution for readings
between –10 dBu and +5 dBu. Reference calibration (–9 dB) is –18 dBFS.
VENUE Provides Peak metering behavior with a meter scale calibrated specifically for Avid VENUE
systems. Reference calibration (0 dB) is –20 dBFS.
