according to https://github.com/chirlu/sox/commit/af261dcc91071cafd7d83054afb1eb4b2d0083ef https://github.com/chirlu/sox/commit/af261dcc91071cafd7d8305..., sox added support for Ogg Vorbis files in 2001, which is a little more than 5 years ago. since sox didn't exist until 1999 and vorbis didn't exist until 2000, that seems like pretty solid format support to me.
