I like the -v option as it shows you what conversion process you are
actually invoking.
If you enter afconvert with no args, it will print out all of its
options - including data formats it can encode.

Hi,
I have been playing around with afconvert in the examples and have
gotten it to convert aac files to aiff. But, it refuses to do the
reverse
with a fmt? error. This could be because I am not supplying the
right file
type (I tried with m4af) or core audio doesn't have a aac encoder?
I read on
a previous post that neither coreaudio nor quicktime has an mp3
encoder. Is
there any place I can look to see what encoders I have installed on
the
system or is there someplace I can find a default list online? Thanks
Regards
George M.P.
