The OS/2 Port by Brian Havard of Ogg Vorbis for OS/2 has been released on Netlabs.org.
From the included readme.os2:
" This package contains a number of OS/2 programs and modules for using Ogg Vorbis files, an audio compression format similar to MP3 but free of patented algorithms and fully open source. More information can be found at
http://www.vorbis.com/
The source code used to build is the v1.1.0 release. See http://silk.apana.org.au/vorbis/ for updates, source code and associated programs."
This includes OggEnc.exe (to compress .wav files to .ogg files), OggPlay.exe, OggPlay.dll (a plugin for PM123), Ogg123.exe (an OGG player) and several utilities for editing and dealing with Ogg files.
