During the Loudness capture, you may now toggle the capture between 'Start' and 'Pause'. The
overall resulting loudness readings will express the summarized capture of all audio above -
70dBFS from the last Reset.
Hitting 'Reset' will re-initiate the Loudness Capture and measures.
Overall, the Start-Pause mode allows you to manually start and stop the capture during breaks
or audio that you do not wish to consider in the overall loudness readings.
Note: As per the BS1770 standards, audio below -70dBFS is not included in the overall
loudness capture. This is to avoid that breaks or silence in the audio undermines the
loudness readings.
Auto-Start Mode
The Auto-Start mode, has controls and options similar to those of the Start-Pause Mode, with
the addition of an automatic start/reset facility triggered by the audio level.
More specifically, if the audio is higher than -70dBFS, the Loudness Capture is automatically
started, as well as being automatically stopped and Reset when the audio drops below -70dBFS
again for more than 2 seconds.
This mode is particularly handy when working with smaller bits of audio, and frees you from
having to manually reset the loudness capture every time you want a new reading.
Loudness Option
The Loudness option section allows you define what loudness parameter you wish displayed as the Loudness
bar-graph as well as setting up the Capture mode of your loudness measurements.
Note: Enabling a Loudness Bar-graph requires audio to be routed to the relevant bar graph position.
Capture
The Loudness capture functionality may be changed between three different modes; Start-
Pause, Auto-Start and Auto-LTC.
Loudness measurement or Capture is essentially always done over a timespan - hence, it is
necessary to define when the Loudness capture starts and stops.
As explained in the Loudness & Terminology section, several different Loudness measures are
relevant i.e. Momentary Loudness, Short-term Loudness, Integrated Loudness and Loudness
Range – all time dependent.
The Start-Pause Mode
Is in effect a manual mode that allows you to decide when the Loudness capture starts, pauses,
restarts or is reset.
The button expresses the Loudness capture state the meter is in, e.g. 'Start' indicates that the
Loudness Captured has been started.
Loudness Capture is dependent on the incoming signal level being higher than -70dBFS.
During the Loudness capture, you may now toggle the capture between 'Start' and 'Pause'. The
overall resulting loudness readings will express the summarized capture of all audio above -
70dBFS from the last Reset.
