-"""Routines to help recognizing sound files.
-
-Function whathdr() recognizes various types of sound file headers.
-It understands almost all headers that SOX can decode.
-
-The return tuple contains the following items, in this order:
-- file type (as SOX understands it)
-- sampling rate (0 if unknown or hard to decode)
-- number of channels (0 if unknown or hard to decode)
-- number of frames in the file (-1 if unknown or hard to decode)
-- number of bits/sample, or 'U' for U-LAW, or 'A' for A-LAW
-
-If the file doesn't have a recognizable type, it returns None.
-If the file can't be opened, OSError is raised.
-
-To compute the total time, divide the number of frames by the
-sampling rate (a frame contains a sample for each channel).
-
-Function what() calls whathdr(). (It used to also use some
-heuristics for raw data, but this doesn't work very well.)
-
-Finally, the function test() is a simple main program that calls
-what() for all files mentioned on the argument list. For directory
-arguments it calls what() for all files in that directory. Default
-argument is "." (testing all files in the current directory). The
-option -r tells it to recurse down directories found inside
-explicitly given directories.
