Hi Ron,

You don't have lots of users on your machine do you? I.e. it's not
possible that you're playing the mp3 file as one user and trying to
encode it as another?

Otherwise the only thing I can suggest is using a tested syntax (I've
tried this on my machine). The -i might make all the difference. So
try:

ffmpeg -i\
/home/gaspode/Music/KitaroEssential/AsTheWindBlows.mp3\
/home/gaspode/Music/Converted/out.wav

(You should be able to just copy and paste that command without fear
of line breaks)
