Convert WAV to DWP

Converting WAVE Audio Files directly to DarkWave Studio Project Files (.wav to .dwp conversion) is certainly doable, but you will need access to the actual DarkWave Studio software.

DarkWave Studio allows you to import WAV audio while creating a project, which can then be saved in DWP format.

It appears that the DWP file type is a proprietary format, and you won't, most likely, find any third-party software, or audio file conversion tools, capable of converting WAV to DWP.
