The official website doesn't specify anything about the process of exporting to WAV files. I recommend checking the built-in Help file. Use the Search function and look for the wav support. The basic way to check for all the export options is through the main menu. Go to File > Save as or File > Export. If there is nowhere mentioned about WAV support, then the software doesn't have this feature.
Secondly, get in touch with the developer and ask for a user guide or if it supports exporting to WAV: http://www.nice.com/contact-us
