12 – 288 Batch processing
Other considerations
• Off-line processors might not have presets.
• Off-line processors that require extra processing “passes”, slightly increase the
overall processing time.
The included off-line processors
• DC Remover. This removes any DC Offset in the file (see “Eliminate DC Offset”
on page 195). This would normally be inserted at the beginning of the processing
list, preparing the file for processing, so to speak.
• Normalizer. This is normally included at the end of the list to get the resulting file
back up into “full level”. Alternatively, it can be inserted in between other proces-
sors when required (for example before the input of a compressor). You can add
as many Normalizers as you need, in between other processors, if required.
• Time Stretch and Pitch Correction. See “Time Stretch” on page 196 and “Pitch
Correction” on page 201.
• Loudness Restorer. This is used to “capture” the loudness at a certain point in the
audio chain and restore that loudness at some other point. For this reason, these
must be inserted in pairs into the signal chain (one plug-in “capturing” and one
“restoring”). Click the question mark icon in the dialog for details.
• Meta Normalizer. This allows you to give all the processed files the same level af-
ter processing. Click the question mark icon in the dialog for details.
• Meta Leveler. This lets you raise the level of all processed files by a certain
amount while maintaining the original level differences between the files. Click the
question mark icon in the dialog for details.
• Resizer. This allows you to set the sample length of a file to a given value.
• Stereo -> Mono. Lets you convert stereo files to mono files and limit the level of
these to avoid clipping.
• Fade-In and Fade-Out. These allow you to apply identical fade-ins and fade-outs
to all the processed files. You can specify the fade curve shape, the length of the
fades and the desired start (fade-in) and end (fade-out) amplitudes.
• External Gear. This is located in the “ASIO” subfolder. This allows you to Batch
process using an external processor – see “Using External effects” on page 252.
Ultra-pass processors
An ultra-pass processor analyses all files in the batch, collects the result,
and applies it to the files by various amounts, if desired. This means that
the result of the analysis of one file, can affect how other files are pro-
cessed. A typical example is the (included) Meta Normalizer, which can
process a number of files so that they all get the same loudness as the
loudest file in the batch. It does this by analyzing all files to find out which
is the loudest (and how loud it is) and then process them all by various
amounts so that they get the same level.
