Dialogue Intelligence enabled
Note:
The dialogue intelligence algorithm in PRISM introduces a latency of 2.048s in
the effective measurement of the short-term and infinite Loudness. Other Loudness
measurement parameters are not affected by the latency.
Note:
The Loudness measurements are updated every 500ms in the user interface.
Note:
Maximum short-term Loudness level can be considered as an alternative to
using Loudness range for short audio clips.

Emphasis Filter
Enable or Disable DC block simulates the effect of
downstream devices that remove DC.
The emphasis filter compensates for
dispersion effects from Nyquist filters in the
broadcast chain that make it difficult to
measure and control the peak levels of
high ‐ frequency signals.
