7.3 Batch Processing Plug-ins 197
Multipass Plug-ins
Multipass plug-ins require two or more passes (an analysis pass followed by a process pass)
before processing the audio. Some are unique to the Batch Processor while others are also
found as Offline Processors in the Audio File Workspace.
The following Multipass plug-ins are available in the Batch Processor Workspace:
Normalize Level
Stereo to Mono
Pan Normalizer
Loudness normalizer
Fade-out
DC Remover
Loudness Restorer
Metapass Plug-ins

7.3.0.2 Trimmer
This dialog is exclusive to the Batch Processor Workspace and allows you to remove a spec-
ified duration (from 0ms to 60s) of audio from the head and/or tail of an Audio File.
You can access this dialog from the Batch Processor Workspace via Plug-ins window>
Monopass Plug-ins >Trimmer .

7.3.0.5 Instructor
This dialog is exclusive to the Batch Processor Workspace and is a special utility plug-in
that allows you to "instruct" the next plug-in in the batch with information about the audio it
needs to process. This is useful for situations where you want to use plug-ins that require
an analysis stage. In effect, the Instructor plug-in turns a monopass plug-in into a dual pass
one.
Some Monopass plugins, such as Denoisers or DeBuzzer, need to learn...

7.3.0.10 Pan Normalizer
This dialog allows you to ensure that both channels of a stereo file have the same level or
loudness. Since loudnesss is more important than peak volume in the perception of sound,
this is a powerful tool to get the best possible stereo balance....

7.3.0.12 DC Remover
This dialog is exclusive to the Batch Processor Workspace and allows you to eliminate any
DC Offset from an Audio File.
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...

7.3.0.14 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 sameloudness 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...

About Podcasts
Once set up, you can produce high quality audio podcast episodes directly from WaveLab.
Audio podcasts are ordered and commented sets of digital Audio Files, generally in the
form of 'episodes' with a consistent theme or presenter. Episodes may be downloaded from
the Internet, usually via an automated feed. Compression is an important consideration in
exporting an audio podcast file, since the listener is likely to encounter bandwidth bottlenecks,
so the file...

Adding information to the Podcast
The upper pane of the Podcast window shows various fields and settings that are related to
the basic Feed or Episode, depending on what you have selected in the lower pane's item
list (the fields are slightly different for the Feed and Episodes).
Field labels in bold letters point at a field that is mandatory to fill. For quick publishing of your
Podcast it is sufficient to fill these fields only.
The following settings are available for the Feed and Episode...
