Processing Precision
WaveLab Pro can load audio samples in many formats. Internally, it processes them as 64-bit float samples.
Mixing inside WaveLab Pro is also done in 64-bit float. 32-bit PCM samples can be transferred to 64-bit float and back.
Plug-ins are processed in 64-bit float by default. You can also set the plug-in processing to 32-bit float.
You can set up the processing precision for plug-ins and for temporary files via the Audio tab of the Global Preferences.
Note
Processing in 64-bit float results in double precision but slightly longer processing times than 32-bit float.
Temporary files in 64-bit float are processed with double precision but take longer to read and write than 32-bit float, and their file size is twice as big.
