Temporary Files
WaveLab Elements creates temporary files to store intermediary results of the audio file processing and for the undo/redo functions. You can specify where WaveLab Elements saves its temporary files and the processing precision of temporary files.
By default, WaveLab Elements creates temporary files in 32-bit float. Use the 64 bit float option if you want to create 64-bit float audio files or 32-bit PCM files.
Note
Temporary files in 64-bit float have double precision but take longer to read and write than 32-bit float and their file size is twice as big.
You can change the processing precision of temporary files with the Processing Precision option. You can set this option in the Global Preferences on the Audio tab.
