thanks greg. It's a bit more informative than sndfile-info, I like that 
it also gives sample length (your example doesn't show it, but it did 
when I ran it.)
 Where'd you get it? Is there an argument that can extract specific 
data? like just the type or just the length?

Does it extract information from the header, or calculate the information?
