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. + |
