audio file trouble.

I I recorded a 30 minute audio file that I was really happy with, and that made me feel a lot better, and I wanted to upload it. Unfortunately, I recorded it through note everything on my phone, so the file is an AMR file. to actually post it, I had to convert it to MP3, then try to make a video using it through windows movie maker, only the one I downloaded doesn't allow audio files. I might figure it out, but as of now I can't post it. It seems a little backwards that I can easily post videos with audio but I can't post just audio. Guess I'll try again later...
