winsound — Sound-playing interface for Windows¶

Thewinsound module provides access to the basic sound-playing machineryprovided by Windows platforms. It includes functions and several constants.

winsound.Beep(frequency,duration)¶

Beep the PC’s speaker. Thefrequency parameter specifies frequency, in hertz,of the sound, and must be in the range 37 through 32,767. Thedurationparameter specifies the number of milliseconds the sound should last. If thesystem is not able to beep the speaker,RuntimeError is raised.

winsound.PlaySound(sound,flags)¶

Call the underlyingPlaySound() function from the Platform API. Thesound parameter may be a filename, a system sound alias, audio data as abytes-like object, orNone. Itsinterpretation depends on the value offlags, which can be a bitwise ORedcombination of the constants described below. If thesound parameter isNone, any currently playing waveform sound is stopped. If the systemindicates an error,RuntimeError is raised.

winsound.MessageBeep(type=MB_OK)¶

Call the underlyingMessageBeep() function from the Platform API. Thisplays a sound as specified in the registry. Thetype argument specifies whichsound to play; possible values are-1,MB_ICONASTERISK,MB_ICONEXCLAMATION,MB_ICONHAND,MB_ICONQUESTION, andMB_OK, alldescribed below. The value-1 produces a “simple beep”; this is the finalfallback if a sound cannot be played otherwise. If the system indicates anerror,RuntimeError is raised.

winsound.SND_FILENAME¶

Thesound parameter is the name of a WAV file. Do not use withSND_ALIAS.

winsound.SND_ALIAS¶

Thesound parameter is a sound association name from the registry. If theregistry contains no such name, play the system default sound unlessSND_NODEFAULT is also specified. If no default sound is registered,raiseRuntimeError. Do not use withSND_FILENAME.

All Win32 systems support at least the following; most systems support manymore:

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

For example:

importwinsound# 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. TheSND_ASYNC flag must also be used toavoid blocking. Cannot be used withSND_MEMORY.

winsound.SND_MEMORY¶

Thesound parameter toPlaySound() is a memory image of a WAV file, as abytes-like object.

Note

This module does not support playing from a memory image asynchronously, so acombination of this flag andSND_ASYNC will raiseRuntimeError.

winsound.SND_PURGE¶

Stop playing all instances of the specified sound.

Note

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.

Note

This flag is not supported on modern Windows platforms.

winsound.MB_ICONASTERISK¶

Play theSystemDefault sound.

winsound.MB_ICONEXCLAMATION¶

Play theSystemExclamation sound.

winsound.MB_ICONHAND¶

Play theSystemHand sound.

winsound.MB_ICONQUESTION¶

Play theSystemQuestion sound.

winsound.MB_OK¶

Play theSystemDefault sound.
