+:mod:`winsound` --- Sound-playing interface for Windows
+=======================================================
+
+.. module:: winsound
+ :platform: Windows
+ :synopsis: Access to the sound-playing machinery for Windows.
+.. moduleauthor:: Toby Dickenson <htrd90@zepler.org>
+.. sectionauthor:: Fred L. Drake, Jr. <fdrake@acm.org>
+
+
+.. versionadded:: 1.5.2
+
+The :mod:`winsound` module provides access to the basic sound-playing machinery
+provided by Windows platforms. It includes functions and several constants.
+
+
+.. function:: Beep(frequency, duration)
+
+ Beep the PC's speaker. The *frequency* parameter specifies frequency, in hertz,
+ of the sound, and must be in the range 37 through 32,767. The *duration*
+ parameter specifies the number of milliseconds the sound should last. If the
+ system is not able to beep the speaker, :exc:`RuntimeError` is raised.
+
+ .. note::
+
+ Under Windows 95 and 98, the Windows :cfunc:`Beep` function exists but is
+ useless (it ignores its arguments). In that case Python simulates it via direct
+ port manipulation (added in version 2.1). It's unknown whether that will work
+ on all systems.
+
+ .. versionadded:: 1.6
+
+
+.. function:: PlaySound(sound, flags)
+
+ Call the underlying :cfunc:`PlaySound` function from the Platform API. The
+ *sound* parameter may be a filename, audio data as a string, or ``None``. Its
+ interpretation depends on the value of *flags*, which can be a bit-wise ORed
+ combination of the constants described below. If the system indicates an error,
+ :exc:`RuntimeError` is raised.
+
+
+.. function:: MessageBeep([type=MB_OK])
+
+ Call the underlying :cfunc:`MessageBeep` function from the Platform API. This
+ plays a sound as specified in the registry. The *type* argument specifies which
+ sound to play; possible values are ``-1``, ``MB_ICONASTERISK``,
+ ``MB_ICONEXCLAMATION``, ``MB_ICONHAND``, ``MB_ICONQUESTION``, and ``MB_OK``, all
+ described below. The value ``-1`` produces a "simple beep"; this is the final
+ fallback if a sound cannot be played otherwise.
+
+ .. versionadded:: 2.3
+
+
+.. data:: SND_FILENAME
+
+ The *sound* parameter is the name of a WAV file. Do not use with
+ :const:`SND_ALIAS`.
+
+
+.. data:: SND_ALIAS
+
+ The *sound* parameter is a sound association name from the registry. If the
+ registry contains no such name, play the system default sound unless
+ :const:`SND_NODEFAULT` is also specified. If no default sound is registered,
+ raise :exc:`RuntimeError`. Do not use with :const:`SND_FILENAME`.
+
+ All Win32 systems support at least the following; most systems support many
+ more:
+
+ +--------------------------+----------------------------------------+
+ | :func:`PlaySound` *name* | Corresponding Control Panel Sound name |
+ +==========================+========================================+
+ | ``'SystemAsterisk'`` | Asterisk |
+ +--------------------------+----------------------------------------+
+ | ``'SystemExclamation'`` | Exclamation |
+ +--------------------------+----------------------------------------+
+ | ``'SystemExit'`` | Exit Windows |
+ +--------------------------+----------------------------------------+
+ | ``'SystemHand'`` | Critical Stop |
+ +--------------------------+----------------------------------------+
+ | ``'SystemQuestion'`` | Question |
+ +--------------------------+----------------------------------------+
+
+ For example::
+
+ import winsound
+ # Play Windows exit sound.
+ winsound.PlaySound("SystemExit", winsound.SND_ALIAS)
+
+ # Probably play Windows default sound, if any is registered (because
+ # "*" probably isn't the registered name of any sound).
+ winsound.PlaySound("*", winsound.SND_ALIAS)
+
+
+.. data:: SND_LOOP
+
+ Play the sound repeatedly. The :const:`SND_ASYNC` flag must also be used to
+ avoid blocking. Cannot be used with :const:`SND_MEMORY`.
+
+
+.. data:: SND_MEMORY
+
+ The *sound* parameter to :func:`PlaySound` is a memory image of a WAV file, as a
+ string.
+
+ .. note::
+
+ This module does not support playing from a memory image asynchronously, so a
+ combination of this flag and :const:`SND_ASYNC` will raise :exc:`RuntimeError`.
+
+
+.. data:: SND_PURGE
+
+ Stop playing all instances of the specified sound.
+
+
+.. data:: SND_ASYNC
+
+ Return immediately, allowing sounds to play asynchronously.
+
+
+.. data:: SND_NODEFAULT
+
+ If the specified sound cannot be found, do not play the system default sound.
+
+
+.. data:: SND_NOSTOP
+
+ Do not interrupt sounds currently playing.
+
+
+.. data:: SND_NOWAIT
+
+ Return immediately if the sound driver is busy.
+
+
+.. data:: MB_ICONASTERISK
+
+ Play the ``SystemDefault`` sound.
+
+
+.. data:: MB_ICONEXCLAMATION
+
+ Play the ``SystemExclamation`` sound.
+
+
+.. data:: MB_ICONHAND
+
+ Play the ``SystemHand`` sound.
+
+
+.. data:: MB_ICONQUESTION
+
+ Play the ``SystemQuestion`` sound.
+
+
+.. data:: MB_OK
+
+ Play the ``SystemDefault`` sound.
+
