Use the unix "file" command (it's available either in the cygwin tools
for windows, or try to compile it yourself), or do the same what "file"
does (look at the file in question and print some information based upon
values at specific offsets) on your own.
Here's the MPEG 1 Layer 3 bitrate specific part of the "magic" file (the
name of the config file) of "file":
