WaveLab Pro Concepts
We recommend that you familiarize yourself with the general concepts of WaveLab Pro, to ensure the highest possible efficiency when using the application.
Peak Files
A peak file (extension .gpk) is automatically created by WaveLab Pro each time an audio file is modified or opened in WaveLab Pro for the first time. The peak file contains information about the waveform and determines how it is drawn in the Audio Editor or in the Audio Montage window.
Rebuilding or Updating Peak Displays
WaveLab Pro automatically updates peak files when the peak file is older than the audio file. If, for any reason, the audio file is not automatically updated, you can force a rebuild of the peak file in the Audio Editor or update the peak files manually in theAudio Montage window.
