In WaveLab there is no limitation to the use of VST plug-ins. They can be used wherever plug-ins can be inserted.
In the Batch Processor window, you can add a sequence of plug-ins that can be used to process a batch of audio files. These plug-ins can be standard plug-ins available from the Master Section, offline processes available in the Audio Editor, and plug-ins that are only available within batch processing.
Audio Analyzer
This plug-in allows you to generate text files with statistics about the audio files in a batch process.
Audio Injector
This plug-in allows you to insert an audio file at the beginning and/or end of the audio file being processed. The inserted file can also be crossfaded with the original audio file, if required.
Audio Mixer
This plug-in allows you to mix an audio file with other audio files. The mix-in happens from a specified time and can optionally be repeated at a specified interval.
DC Remover
This plug-in allows you to remove any DC Offset from an audio file.
Delay Next Process Activation
This plug-in allows you to delay the processing of the next VST plug-in in the plug-in chain for a certain time.
Fade In/Fade Out
This plug-in allows you to fade the beginning (Fade In) or the end (Fade Out) of a batch audio file. You can choose the length and shape of the fade, its duration, and the gain you want it to start/end at.
Instructor
Instructor 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 monopass plug-ins that require an analysis stage that is not available at this point.
Level Normalizer
This multipass plug-in allows you to raise or lower levels so that the signal peaks exactly at the specified value just before it is converted to a file.
Loudness Meta Normalizer
The Loudness Meta Normalizer batch plug-in allows you to change the loudness level of a batch of files, while maintaining a consistent loudness ratio among them.
Loudness Restorer
Loudness Restorer captures the loudness at a specific point in the audio chain and restores that loudness at another point. For this reason, the Loudness Restorer must be inserted in pairs into the signal chain: one plug-in for capturing and one plug-in for restoring.
Meta Leveler
The Meta Leveler plug-in allows you to adjust the levels of all files in a batch by the same value.
Resizer
This plug-in allows you to specify the duration of all audio files in the batch, and to choose whether to insert silence after the end of the chosen duration.
Stereo to Mono
This plug-in allows you to mix a stereo signal down to a mono signal while being certain not to clip while mixing channels because of the multipass approach. You can choose to use the same peak level that the stereo file contains, or set the gain to be applied and/or the maximum level to be reached in the resulting mono file.
Trimmer
This plug-in allows you to remove a specified duration (from 0 ms to 60 s) of audio from the head and/or tail of an audio file.
