What is a gpk file and how do I open a gpk file?
A WaveLab audio peak file is a file created by the WaveLab software, and these WaveLab audio peak files are implemented with encoding and compression specifications proprietary to Steinberg, developer of the WaveLab application. Steinberg also developed the GPK format as the format of these WaveLab audio peak files, which are created by the WaveLab program once a user opens an audio file with the program. The associated sound wave details of an audio file is stored in the newly generated GPK file to speed up the process of loading files unto the WaveLab program. The GUI (Graphical User Interface) of the WaveLab application, then displays visualized details and other metadata info for the user to analyze sound wave data associated to the corresponding audio file that was opened by the WaveLab user. The WaveLab default configuration for these GPK files is to leave these GPK files stored in a predefined directory, normally the same directory where the program files of the WaveLab program are found. Users can change this default configuration by selecting the option where the WaveLab program will automatically delete the associated GPK file once the audio file is unloaded by the user from the program.
