The winsound
module provides access to the basic sound-playing machinery provided by Windows platforms. It includes functions and several constants.
winsound.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, RuntimeError
is raised.
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:
| Corresponding Control Panel Sound name |
---|---|
| Asterisk |
| Exclamation |
| Exit Windows |
| Critical Stop |
| Question |
例如:
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.
注解
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.
注解
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.
注解
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.
