[FFmpeg-user] Strange Wav (PCM) file (isn't playing correctly)

[Andrey Aleksandrovich]

I have old game (Anno 1602), and there's nice soundtrack playing
during the game. The file is here

But I can't understand, what codec this audio is compressed by. All
known media players play it with distortion. In the Game this music is
playing correctly.
Here is that music recorded by 'what I hear' method (system sound grabber):

If anyone know what is that codec, please help me to convert it.
