winsound —- Sound-playing interface for Windows
The winsound
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. 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 thesystem is not able to beep the speaker,
RuntimeError
is raised.Call the underlying
PlaySound()
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 of flags, which can be a bitwise ORedcombination of the constants described below. If the sound parameter isNone
, any currently playing waveform sound is stopped. If the systemindicates an error,RuntimeError
is raised.Call the underlying
MessageBeep()
function from the Platform API. Thisplays a sound as specified in the registry. The type 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.The sound parameter is the name of a WAV file. Do not use with
SND_ALIAS
.- The sound parameter is a sound association name from the registry. If theregistry contains no such name, play the system default sound unless
SND_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
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 toavoid blocking. Cannot be used withSND_MEMORY
.- The sound parameter to
PlaySound()
is a memory image of a WAV file, as abytes-like object.
注解
This module does not support playing from a memory image asynchronously, so acombination of this flag and SND_ASYNC
will raise RuntimeError
.
注解
This flag is not supported on modern Windows platforms.
winsound.
SND_ASYNC
Return immediately, allowing sounds to play asynchronously.
If the specified sound cannot be found, do not play the system default sound.
Do not interrupt sounds currently playing.
- Return immediately if the sound driver is busy.
注解
This flag is not supported on modern Windows platforms.
