text: There are ways to speed up audio content, but you need sophisticated software to do so. At least speed it up and maintain the pitch, that is.  I use Digital Performer. It is an amazing audio recording program that does everything, including time shifting audio. I have not tried to import a .wma file, but I think it might do that. Post the file somewhere and I'll give it a try. BTW, why do you want to double speed it?
