Audio Tab (Global Preferences)

This tab allows you to change audio preferences like the processing precision.

  • To open the Audio tab of the Global Preferences, select File > Preferences > Global and click Audio.

Resample Conversion Quality

Allows you to specify the resample conversion quality.

Default Fade/Crossfade

Allows you to specify the default duration and shape of the fades or crossfades that WaveLab Pro creates automatically during specific processes.

Processing Precision

Plug-in Processing allows you to select the processing precision for plug-ins.

  • If you select 64 bit float and a plug-in is capable of processing 64-bit samples, processing takes place in lossless 64 bit.

    If a plug-in is only capable of handling 32-bit samples, WaveLab Pro converts all 64-bit float samples to 32-bit float before sending them to the plug-in. After the plug-in processing is completed, WaveLab Pro converts the 32-bit float samples back to 64-bit float without loss.

  • If you select 32 bit float, WaveLab Pro converts all 64-bit float samples to 32-bit float before sending them to the plug-in. After the plug-in processing is completed, WaveLab Pro converts the 32-bit float samples back to 64-bit float without loss.

In the plug-in menus, the “32F” and “64F” indicators next to the plug-in name show whether a plug-in is capable of 32-bit float or 64-bit float.

Note

Processing in 64-bit float means double precision but slightly longer process time than 32-bit float.

Temporary Files allows you to select the precision of temporary files that WaveLab Pro creates when processing audio.

By default, WaveLab Pro creates temporary files in 32-bit float. Use 64 bit float 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.
