AUPEC stands for Auckland University Perceptual Entropy Coder (g2 is for generation 2), a very obscure lossy audio format that was developed by Mark Vinton as his undergraduate research project.

Quality is not good, partially because no stereo redundancy coding is used - the channels are coded independently. Other limitations of the format are only CBR encoding, no multichannel support, and it is not documented at all.

The web page at Washington University is gone, but you can still find it at the Internet Archive.
