i decided to make some noise about those, as people may thinking
about doing the ports themselves, and effectively double (or
triple, or...) the work.
so, here they are:
* Vorbis decoder (stb_vorbis port), PD;
* FLAC decoder (drflac port), PD;
* MP3 decoder (minimp3 port), GPL.
they may or may not work for you, i don't know.
