MP3 surround not identified as it #128

This is a rare format version use, though i accidentaly found some samples from a commercial website. It's recognized as standard MP3, but i guess that in reality it's perhaps something like MPEG-2 Part 3 (ISO/IEC 13818-3) (but retrocompatible to standard MP3)

At my knowledge, only Playstation 3/4 are able to play them fully/correctly, except professional stuff and very few softwares.

Perhaps having a look at this code could help ? https://sourceforge.net/p/drdivx/code/HEAD/tree/DrDivX/trunk/drffmpeg/libavcodec/mp3sencoder.h https://sourceforge.net/p/drdivx/code/HEAD/tree/DrDivX/trunk/drffmpeg/libavcodec/mp3surround.c
