winsound — Interface de reprodução de som para Windows

---

O módulo winsound fornece acesso ao mecanismo básico de reprodução de som fornecido pelas plataformas Windows. Inclui funções e várias constantes.

winsound.Beep(frequency, duration)

Emite um bipe no alto-falante do PC. O parâmetro frequency especifica a frequência, em hertz, do som e deve estar no intervalo de 37 a 32.767. O parâmetro duration especifica o número de milissegundos que o som deve durar. Se o sistema não conseguir emitir um bipe no alto-falante, RuntimeError é levantado.

winsound.PlaySound(sound, flags)

Call the underlying PlaySound() function from the Platform API. The sound parameter may be a filename, a system sound alias, audio data as a bytes-like object, or None. Its interpretation depends on the value of flags, which can be a bitwise ORed combination of the constants described below. If the sound parameter is None, any currently playing waveform sound is stopped. If the system indicates an error, RuntimeError is raised.

winsound.MessageBeep(type=MB_OK)

Call the underlying 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. If the system indicates an error, RuntimeError is raised.

winsound.SND_FILENAME

The sound parameter is the name of a WAV file. Do not use with SND_ALIAS.

winsound.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 SND_NODEFAULT is also specified. If no default sound is registered, raise RuntimeError. Do not use with SND_FILENAME.

All Win32 systems support at least the following; most systems support many more:

PlaySound() name	Corresponding Control Panel Sound name
'SystemAsterisk'	Asterisk
'SystemExclamation'	Exclamation
'SystemExit'	Exit Windows
'SystemHand'	Critical Stop
'SystemQuestion'	Question

Por exemplo:

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)

winsound.SND_LOOP

Play the sound repeatedly. The SND_ASYNC flag must also be used to avoid blocking. Cannot be used with SND_MEMORY.

winsound.SND_MEMORY

The sound parameter to PlaySound() is a memory image of a WAV file, as a bytes-like object.

Nota

This module does not support playing from a memory image asynchronously, so a combination of this flag and SND_ASYNC will raise RuntimeError.

winsound.SND_PURGE

Stop playing all instances of the specified sound.

Nota

This flag is not supported on modern Windows platforms.

winsound.SND_ASYNC

Return immediately, allowing sounds to play asynchronously.

winsound.SND_NODEFAULT

If the specified sound cannot be found, do not play the system default sound.

winsound.SND_NOSTOP

Do not interrupt sounds currently playing.

winsound.SND_NOWAIT

Return immediately if the sound driver is busy.

Nota

This flag is not supported on modern Windows platforms.

winsound.MB_ICONASTERISK

Play the SystemDefault sound.

winsound.MB_ICONEXCLAMATION

Play the SystemExclamation sound.

winsound.MB_ICONHAND

Play the SystemHand sound.

winsound.MB_ICONQUESTION

Play the SystemQuestion sound.

winsound.MB_OK

Play the SystemDefault sound.
