This is called the PS22 Stereo Maker plug-in from Waves Audio. This is only a stereo spreader, but that is actually a minor detail.
Essentially, judging from the stereo spreading curve presented in the paper, even the digital kind is pretty simple. I'd bet it's an M/S architecture with a stereo spreader mostly revolving around a long delay line in the side/S channel. Otherwise, the delay network used would have to be unitary in order to preserve frequency response, but then, after that, it seems rather simple. Much simpler than unitary feedback networks could be even within the center/mid channel, nowadays. ;)
