Like thousands of other users I religiously used Skype to communicate with many friends and coworkers back in the early 2010s. It was a great platform, with the ability to send messages fluently from computer to phone and vice-versa, as well as make long and drawn out video calls. You could purchase a telephone number from anywhere in the world to have a presence in that country (as I did), and with it you gained voicemail. It did everything perfectly except save voicemails in a reusable format.

I’m not the only person that has a need/want to listen to these types of audio. There are forums of people who have their own needs, such as fathers voices and passed family members. The common solutions proposed are “download VLC”, “use Microsoft Word and run a repair”, or use a “DAT player”, all are non-functional or stupid solutions. There is a ton of common use cases for these old files and the technical solutions are far and none between.

Skype voicemails, once listened to, were downloaded from the Skype servers and stored in the users Skype profile as a dat file. Unfortunately, “dat” files are a general file format and have no immediate player that can open and listen to those files.

Time to dig in. Challenge Accepted!
