I am urgently looking for an audio library able to play .ogg files in Borland Delphi. I would use FMod or BASS, but both are too expensive in the commercial version and both seem not willing to give me any written license for the shareware version fee. Can someone help me with this please? I can't find any relevant other players on the web for days...

Ogg Vorbis?

Yes, which would open up the problem of how to include it in Delphi. Using a pre-made audio library like FMod is one thing, writing the code all myself something else. After all I am more a game designer than a programmer. If someone is skilled enough to do this and wants to earn some cash, please email me.

You can download ogg/vorbis from the site (www.xiph.org I believe).
Then you can compile it (eg try the free edition of visual studio),
it will generate some dll's.

I'm sure it's possible to load dll's from within delphi - then
all you need to do is feed the vorbis stream to for example
openAL (dunno if there is a delphi version for openAL).
