It can be useful to apply this plug-in first in a batch before other plug-ins to avoid further
processing a file containing any DC Offset. For example, an Audio File that has a DC offset
will not be at its loudest possible volume when normalized, because the offset consumes
headroom.
You can access this dialog from the Batch Processor Workspace via Plug-ins window >
Multipass Plug-ins > DC Remover.

7.1.2.13 Loudness Restorer
This dialog is exclusive to the Batch Processor Workspace and allows you to restore the
loudness of an Audio File.
The Loudness Restorer plug-in must be used as a pair - the first instance is used to read
the audio signal, the second instance uses this information to adjust the loudness or peak
level of the file.
To use the plug-in:
1. Place an instance of the plug-in in the batch chain and choose "Capture" as the mode.
2. Place a second instance of the plug-in after the first one and choose either "Restore
peak level" or "Restore loudness (RMS)".
You can access this dialog from the Batch Processor Workspace via Plug-ins window >
Multipass Plug-ins > Loudness Restorer.

7.1.2.14 Meta-Normalizer
This dialog is exclusive to the Batch Processor Workspace and allows you to normalize a
batch of files all to the same level.
The core purpose of this plug-in is to achieve the same loudness in all files (the highest
loudness found, if possible), while being certain that no file will clip. For each file, a specific
gain is computed by the plug-in once all files have been analyzed and prior to actually applying
any gain to achieve the common loudness. If it is not possible to match the highest found
loudness, the level of the file with the highest loudness is reduced, so that other files can get
the same loudness.
