256 kilobit mp3?  I don't know if I have one that is so little compressed.  
The most I've picked up here & there was 96 and below, usually with an un-
known history. Even 128kbit mp3 can be detected in a few seconds.  Here I 
have done a/b testing against some well produced cd's I've ripped, and 
with ogg running at Q7, which gives a filesize similar to an mp3 at 128kb, 
and cannot tell the difference.  Back these ears up 55 years to before I 
started wearing out rifle barrels, and I expect they might detect the
