mp3PRO is a proprietary codec that is no longer maintained. Its goal was to supersede the mp3 format with a better compression ratio that had comparable audio quality or better (see their archived site for an introduction). It used SBR (spectral-band replication), which is lossy compression, but in a way indistinguishable to the human ear. The site seems to have vanished around 2015.
