I have tried all possible ways of converting amr (recorded on my mobile phone) to mp3 so that I can upload in myspace, with no luck. I was following this post, but both ffmpeg seems to be broken for ubuntu 10.04 and the other product by miksoft doesn't have the amr -> mp3 conversion option. Problem is myspace doesn't accept any format other than mp3, and I have only amr files. Did anybody face a similar problem? Please advise if you have found any way of doing the same.
