(i) Max Short-term Loudness.

Sets the target value for MaxS. Overall file level will

be reduced to ensure this target value is not exceeded. This setting is unavailable

if DynApt™ is turned on - use the Max Short-term Above Int option instead.

5. Dynamics Adaptation With the exception of the LRA test criteria, this section is

disabled unless you have purchased and activated a valid license for the DynApt™

add-on.

DynApt™ is a proprietary algorithm which analyses the loudness levels throughout a

piece of audio and then carefully reduces the loudness range of the audio, according

to several measures, while preserving the short-term dynamics and ”space” in the

audio, and ensuring the dialog level results in good intelligibility. The end result is

audio that has been re-purposed for different play-out contexts, while doing minimal

damage to the original sound and feel of the audio. Example uses are re-purposing

cinema sound-tracks for TV broadcast, or re-purposing radio broadcast programming

for podcast.

(a) DynApt™ Presets Use this option to select the target audience for the DynApt™

algorithm. To customise the settings, click on the settings button to the right.

(b) DynApt™ Settings Here you can set the specific settings used by the DynApt™

algorithm.

i. Loudness Compression Ratio When DynApt™ reduces MMAI and MSAI the

Loudness Compression Ratio controls how hard or soft the compression will

be, with 1.0 being very hard and 0.3 being very soft.

ii. Macro Transition Threshold DynApt™ respects the transitions in the

original audio. The Macro Transition Threshold controls the detection of

transitions. A lower number will detect more transitions.

iii. Time Smoothing (secs) DynApt™ processing is generally applied in a

time-smoothed way. The parameter Time Smoothing controls how many

seconds the processing is smoothed over.

iv. Ignore Transitions Relative to Integrated DynApt™ will ignore transitions

it detects if the loudness levels on both sides of the transition are sufficiently

low. This level is controlled by the Ignore Transitional Relative to Integrated

parameter.

for the file. If the DynApt™ extension is not available then marking this criteria

as required will cause the file to fail if it is not met. AMB will only correct for LRA

when DynApt™ is available.

(d) Max Dialog Below Int. Only available when using DynApt™ . This is a measure

of the difference between the integrated loudness of the whole file compared with

the integrated loudness of the sections containing dialog. This will be reduced to

make sure that the target level is not exceeded.

Reporting

The reporting tab allows you to specify what information is logged out when files are

processed. You can disable all reporting on the processes tab.
