I tried searching for this answer but didn't find quite what I was looking for. I have a file that I recorded with Voice Recorder app. It is saved as a .AMR file. I'd like to use this as a ringtone and send it to my wife to use on her PRE as a ringtone as well. I assume that I have to get it to a more usable format, like .MP3. Does anyone have any thoughts on how to do this?
