Music in Heroes of Might and Magic I.

I found some music on my computer after installing the first Heroes game.
It's located in the Sounds folder of the game.
There are 49 sound files with the extension ogg - "HEROESXX.ogg".

On the "Igrovania" disc, all the music was made into separate files in the standard *.wma (or even *.mp3) format. :(

Is it possible to extract the music from this "HEROESXX.ogg" file somehow?
