WAVELAB
12 – 276 Batch processing
During pass three, the signal is processed by the DC Remover, the first
Normalizer, the Denoiser and Compressor and is analysed by the second
Normalizer. Again, nothing is saved to disk, the only purpose of this pass
is to gather information about how much normalization will be required.
Time for pass four. Now all information has been gathered so that all the
real processing and disk writing can take place during one single pass.
Thanks to the unique WaveLab technology, the process finishes much
faster than if the file had been read and written to disk by each processor.
Furthermore, rounding errors are reduced to a minimum since the audio
never leaves the “32 bit domain” (no temporary file is created). This in-
creases the overall sound quality even further!
Opening the Batch Processor
“Use Master Section” (on the Options menu) must be active for batch pro-
cessing to be available!
There are three basic ways of opening the Batch Processor:
• From the Tools menu.
This gives you a “clean slate” to start with. You can open as many Batch Processor windows
as you like.
• From the Render dialog (see “Rendering” on page 239).
This takes the current settings in the Master window and converts them into a process list
(a sequence).
• By using the Auto Split function - see “The Auto Split dialog” on page 342.
For the Batch Processor button to be available in the Render dialog, “Whole
file” must be selected and “No tail” must be disabled!
