-:mod:`sunau` --- Read and write Sun AU files
-============================================
-
-.. module:: sunau
-   :synopsis: Provide an interface to the Sun AU sound format.
-   :deprecated:
-
-.. sectionauthor:: Moshe Zadka <moshez@zadka.site.co.il>
-
-**Source code:** :source:`Lib/sunau.py`
-
-.. deprecated-removed:: 3.11 3.13
-   The :mod:`sunau` module is deprecated
-   (see :pep:`PEP 594 <594#sunau>` for details).
-
---------------
-
-The :mod:`sunau` module provides a convenient interface to the Sun AU sound
-format.  Note that this module is interface-compatible with the modules
-:mod:`aifc` and :mod:`wave`.
-
-An audio file consists of a header followed by the data.  The fields of the
-header are:
-
-+---------------+-----------------------------------------------+
-| Field         | Contents                                      |
-+===============+===============================================+
-| magic word    | The four bytes ``.snd``.                      |
-+---------------+-----------------------------------------------+
-| header size   | Size of the header, including info, in bytes. |
-+---------------+-----------------------------------------------+
-| data size     | Physical size of the data, in bytes.          |
-+---------------+-----------------------------------------------+
-| encoding      | Indicates how the audio samples are encoded.  |
-+---------------+-----------------------------------------------+
-| sample rate   | The sampling rate.                            |
-+---------------+-----------------------------------------------+
-| # of channels | The number of channels in the samples.        |
-+---------------+-----------------------------------------------+
-| info          | ASCII string giving a description of the      |
-|               | audio file (padded with null bytes).          |
-+---------------+-----------------------------------------------+
-
-Apart from the info field, all header fields are 4 bytes in size. They are all
-32-bit unsigned integers encoded in big-endian byte order.
-
-The :mod:`sunau` module defines the following functions:
-
-
-.. function:: open(file, mode)
-
-   If *file* is a string, open the file by that name, otherwise treat it as a
-   seekable file-like object. *mode* can be any of
-
-   ``'r'``
-      Read only mode.
-
-   ``'w'``
-      Write only mode.
-
-   Note that it does not allow read/write files.
-
-   A *mode* of ``'r'`` returns an :class:`AU_read` object, while a *mode* of ``'w'``
-   or ``'wb'`` returns an :class:`AU_write` object.
-
-
-The :mod:`sunau` module defines the following exception:
-
-.. exception:: Error
-
-   An error raised when something is impossible because of Sun AU specs or
-   implementation deficiency.
-
-
-The :mod:`sunau` module defines the following data items:
-
-.. data:: AUDIO_FILE_MAGIC
-
-   An integer every valid Sun AU file begins with, stored in big-endian form.  This
-   is the string ``.snd`` interpreted as an integer.
-
-
-.. data:: AUDIO_FILE_ENCODING_MULAW_8
-          AUDIO_FILE_ENCODING_LINEAR_8
-          AUDIO_FILE_ENCODING_LINEAR_16
-          AUDIO_FILE_ENCODING_LINEAR_24
-          AUDIO_FILE_ENCODING_LINEAR_32
-          AUDIO_FILE_ENCODING_ALAW_8
-
-   Values of the encoding field from the AU header which are supported by this
-   module.
-
-
-.. data:: AUDIO_FILE_ENCODING_FLOAT
-          AUDIO_FILE_ENCODING_DOUBLE
-          AUDIO_FILE_ENCODING_ADPCM_G721
-          AUDIO_FILE_ENCODING_ADPCM_G722
-          AUDIO_FILE_ENCODING_ADPCM_G723_3
-          AUDIO_FILE_ENCODING_ADPCM_G723_5
-
-   Additional known values of the encoding field from the AU header, but which are
-   not supported by this module.
-
-
-.. _au-read-objects:
-
-AU_read Objects
----------------
-
-AU_read objects, as returned by :func:`.open` above, have the following methods:
-
-
-.. method:: AU_read.close()
-
-   Close the stream, and make the instance unusable. (This is  called automatically
-   on deletion.)
-
-
-.. method:: AU_read.getnchannels()
-
-   Returns number of audio channels (1 for mono, 2 for stereo).
-
-
-.. method:: AU_read.getsampwidth()
-
-   Returns sample width in bytes.
-
-
-.. method:: AU_read.getframerate()
-
-   Returns sampling frequency.
-
-
-.. method:: AU_read.getnframes()
-
-   Returns number of audio frames.
-
-
-.. method:: AU_read.getcomptype()
-
-   Returns compression type. Supported compression types are ``'ULAW'``, ``'ALAW'``
-   and ``'NONE'``.
-
-
-.. method:: AU_read.getcompname()
-
-   Human-readable version of :meth:`getcomptype`.  The supported types have the
-   respective names ``'CCITT G.711 u-law'``, ``'CCITT G.711 A-law'`` and ``'not
-   compressed'``.
-
-
-.. method:: AU_read.getparams()
-
-   Returns a :func:`~collections.namedtuple` ``(nchannels, sampwidth,
-   framerate, nframes, comptype, compname)``, equivalent to output of the
-   :meth:`get\*` methods.
-
-
-.. method:: AU_read.readframes(n)
-
-   Reads and returns at most *n* frames of audio, as a :class:`bytes` object.  The data
-   will be returned in linear format.  If the original data is in u-LAW format, it
-   will be converted.
-
-
-.. method:: AU_read.rewind()
-
-   Rewind the file pointer to the beginning of the audio stream.
-
-The following two methods define a term "position" which is compatible between
-them, and is otherwise implementation dependent.
-
-
-.. method:: AU_read.setpos(pos)
-
-   Set the file pointer to the specified position.  Only values returned from
-   :meth:`tell` should be used for *pos*.
-
-
-.. method:: AU_read.tell()
-
-   Return current file pointer position.  Note that the returned value has nothing
-   to do with the actual position in the file.
-
-The following two functions are defined for compatibility with the  :mod:`aifc`,
-and don't do anything interesting.
-
-
-.. method:: AU_read.getmarkers()
-
-   Returns ``None``.
-
-
-.. method:: AU_read.getmark(id)
-
-   Raise an error.
-
-
-.. _au-write-objects:
-
-AU_write Objects
-----------------
-
-AU_write objects, as returned by :func:`.open` above, have the following methods:
-
-
-.. method:: AU_write.setnchannels(n)
-
-   Set the number of channels.
-
-
-.. method:: AU_write.setsampwidth(n)
-
-   Set the sample width (in bytes.)
-
-   .. versionchanged:: 3.4
-      Added support for 24-bit samples.
-
-
-.. method:: AU_write.setframerate(n)
-
-   Set the frame rate.
-
-
-.. method:: AU_write.setnframes(n)
-
-   Set the number of frames. This can be later changed, when and if more  frames
-   are written.
-
-
-.. method:: AU_write.setcomptype(type, name)
-
-   Set the compression type and description. Only ``'NONE'`` and ``'ULAW'`` are
-   supported on output.
-
-
-.. method:: AU_write.setparams(tuple)
-
-   The *tuple* should be ``(nchannels, sampwidth, framerate, nframes, comptype,
-   compname)``, with values valid for the :meth:`set\*` methods.  Set all
-   parameters.
-
-
-.. method:: AU_write.tell()
-
-   Return current position in the file, with the same disclaimer for the
-   :meth:`AU_read.tell` and :meth:`AU_read.setpos` methods.
-
-
-.. method:: AU_write.writeframesraw(data)
-
-   Write audio frames, without correcting *nframes*.
-
-   .. versionchanged:: 3.4
-      Any :term:`bytes-like object` is now accepted.
-
-
-.. method:: AU_write.writeframes(data)
-
-   Write audio frames and make sure *nframes* is correct.
-
-   .. versionchanged:: 3.4
-      Any :term:`bytes-like object` is now accepted.
-
-
-.. method:: AU_write.close()
-
-   Make sure *nframes* is correct, and close the file.
-
-   This method is called upon deletion.
-
-Note that it is invalid to set any parameters after calling  :meth:`writeframes`
-or :meth:`writeframesraw`.

-"""Stuff to parse Sun and NeXT audio files.
-
-An audio file consists of a header followed by the data.  The structure
-of the header is as follows.
-
-        +---------------+
-        | magic word    |
-        +---------------+
-        | header size   |
-        +---------------+
-        | data size     |
-        +---------------+
-        | encoding      |
-        +---------------+
-        | sample rate   |
-        +---------------+
-        | # of channels |
-        +---------------+
-        | info          |
-        |               |
-        +---------------+
-
-The magic word consists of the 4 characters '.snd'.  Apart from the
-info field, all header fields are 4 bytes in size.  They are all
-32-bit unsigned integers encoded in big-endian byte order.
-
-The header size really gives the start of the data.
-The data size is the physical size of the data.  From the other
-parameters the number of frames can be calculated.
-The encoding gives the way in which audio samples are encoded.
-Possible values are listed below.
-The info field currently consists of an ASCII string giving a
-human-readable description of the audio file.  The info field is
-padded with NUL bytes to the header size.
-
-Usage.
-
-Reading audio files:
-        f = sunau.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' or 'ULAW')
-        getcompname()   -- returns human-readable version of
-                           compression type ('not compressed' matches 'NONE')
-        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 audio files:
-        f = sunau.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 pathing 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.
