External Editors
You can integrate external editors, for example, SpectraLayers, Melodyne 4, or Izotope RX, into your WaveLab Pro workflow. This allows you to modify audio files and clips in one or more external editors directly from within your current WaveLab Pro session.
You can use external editors before or after you use clip effects on the audio clip. However, we recommend that you edit the clip in the external editors before you add clip effects. This workflow requires less processing power.
Your edits are applied to a copy of the source audio. This means that you are editing in a non-destructive environment. For audio montages, WaveLab Pro creates temporary files in the DATA folder of the audio montage. For audio files, WaveLab Pro creates temporary files in the user location or in the location that you have defined in the Folders tab in the Preferences.
