-"""Stuff to parse WAVE files.
-
-Usage.
-
-Reading WAVE files:
-      f = wave.open(file, 'r')
-where file is either the name of a file or an open file pointer.
-The open file pointer must have methods read(), seek(), and close().
-When the setpos() and rewind() methods are not used, the seek()
-method is not  necessary.
-
-This returns an instance of a class with the following public methods:
-      getnchannels()  -- returns number of audio channels (1 for
-                         mono, 2 for stereo)
-      getsampwidth()  -- returns sample width in bytes
-      getframerate()  -- returns sampling frequency
-      getnframes()    -- returns number of audio frames
-      getcomptype()   -- returns compression type ('NONE' for linear samples)
-      getcompname()   -- returns human-readable version of
-                         compression type ('not compressed' linear samples)
-      getparams()     -- returns a namedtuple consisting of all of the
-                         above in the above order
-      getmarkers()    -- returns None (for compatibility with the
-                         aifc module)
-      getmark(id)     -- raises an error since the mark does not
-                         exist (for compatibility with the aifc module)
-      readframes(n)   -- returns at most n frames of audio
-      rewind()        -- rewind to the beginning of the audio stream
-      setpos(pos)     -- seek to the specified position
-      tell()          -- return the current position
-      close()         -- close the instance (make it unusable)
-The position returned by tell() and the position given to setpos()
-are compatible and have nothing to do with the actual position in the
-file.
-The close() method is called automatically when the class instance
-is destroyed.
-
-Writing WAVE files:
-      f = wave.open(file, 'w')
-where file is either the name of a file or an open file pointer.
-The open file pointer must have methods write(), tell(), seek(), and
-close().
-
-This returns an instance of a class with the following public methods:
-      setnchannels(n) -- set the number of channels
-      setsampwidth(n) -- set the sample width
-      setframerate(n) -- set the frame rate
-      setnframes(n)   -- set the number of frames
-      setcomptype(type, name)
-                      -- set the compression type and the
-                         human-readable compression type
-      setparams(tuple)
-                      -- set all parameters at once
-      tell()          -- return current position in output file
-      writeframesraw(data)
-                      -- write audio frames without patching up the
-                         file header
-      writeframes(data)
-                      -- write audio frames and patch up the file header
-      close()         -- patch up the file header and close the
-                         output file
-You should set the parameters before the first writeframesraw or
-writeframes.  The total number of frames does not need to be set,
-but when it is set to the correct value, the header does not have to
-be patched up.
-It is best to first set all parameters, perhaps possibly the
-compression type, and then write audio frames using writeframesraw.
-When all frames have been written, either call writeframes(b'') or
-close() to patch up the sizes in the header.
-The close() method is called automatically when the class instance
-is destroyed.
