MXFix™ (Batch Export, Re-Wrapping) : Final Check Meter Page 107
Standard Standard processing is deemed by Jünger Audio as a suitable all-around dynamic
preset setting for correction of most basic audiovisual programs ready for broad-
cast with a relatively restrained dynamic range that need to meet loudness compli-
ance standards.
Light (Movie) Light (Movie) processing is intended to be suitable for cinema content with a
higher overall dynamic range than typical television or radio content where
smooth perceptual transition is preferred over tight control of broad dynamic tran-
sitions more commonly found in dramatic movie content and not TV, action films
or rock concerts, etc.
Strong (Live) Strong (Live) processing is intended to be suitable for content with high overall
levels and extreme dynamic transitions common to live events, action films and
sporting events, that need to be tightly contained within specifications.
No (Expert settings) When selected, the settings will be in accordance with the settings made in the
Expert Settings dialog.
Note: These four mutually exclusive options apply to whichever Loudness Compliance Standard Mode
is chosen above, Level Magic, EBU R128 or ITU.1770 (ATSC) .
FinalCheck Loudness Normalizer (2-pass)
When selected, this invokes a two-pass normalizing process. The first pass measures audio loudness according to
the channels description. The second pass applies the required gain correction to achieve the loudness value set
in the
Target Loudness drop-down.
When required a True Peak limiter is also activated to ensure that the maximum True Peak value is below -1dBTP
The gain correction is however, limited to 15dB to avoid excessive correction of channels containing only back-
ground sounds etc.
Note: If correction of over 15dB is required then no gain adjustment will be applied and the
MXFix reports will signal a warning.
The gain correction is applied to the entire channel to avoid altering the original balance and is, of course, linked
across the entire group of channels to maintain image veracity.
Target Loudness The drop-down list offers a choice of average loudness target values from -20LUFS
to -30LUFS.
FinalCheck Meter & report
Click on the label to toggle the process on/off. The green LED indicates process on.
The output of Final Check Meter is an XML report file in the same directory as the wrapped file. This file will include
measurements of integrated, momentary and short-term loudness values, as well as the loudness range and the
maximum true peak. All these measurements may be checked against the recommendations, delivery require-
ments or local regulations in force regarding loudness. When LevelMagic is combined with FinalCheck, the mea-
surements are made on the output of LevelMagic, so that the measurements are always consistent with the
content of the wrapped files.
Audio channel content description
The sub-panel provides sufficient information to the processing plug-ins as to how they should deal with the
channels to be Wrapped. Channels are shown by pairs but this will be modified into larger groups if some are
described as 5.1 Surround (I.e. 6 channels involved).
Process On/Off When checked the channel pair or channel group will be processed
Channels description Checkboxes determine the Channel type for processing
Stereo A pair of discrete stereo channels.
5.1 Surround 6 discrete channels in L , R , C , Ls , Rs , LFE order.
Dolby E A pair of Dolby E encoded channels, corresponding to 8 discrete channels
(usually 2 stereo and 6 surround) When this option is selected the source
channel is and will remain a Dolby E stream. If corrections are needed the
stream is decoded corrected and re-encoded to a Dolby E stream.
