[ale] converting audio file

[drifter at oppositelock.org (Sean)]

I used my wife's Mac laptop to record an audio file. The software recorded
the file in AIFF/Amiga Audio format.

That's slick.  I think.

But I really would like to convert it to a wav file so I can burn it to a 
CD and send it off to my grandson for his birthday. The only software
on this box that will play the file is Kaffeine and I can't figure out how 
to make that ap save the file in another format.  If I could change it
to a wav file, I'd have more options.

Hints would be appreciated.
