mp3 sounds distorted

I can’t make this mp3 working properly in my fla. When I publish, the mp3 sounds distorted, with a wrong frequency. I don’t think it’s a matter of actionscript (with other mp3 everything work fine).
I tried to improve the quality of audio publish settings, but it doesn’t work anyway.
I would attach the file , but when i try this explorer freezes

Anyone can help me out?

Thanks a lot in advance
