winsound
— Windows 声音播放接口
¶
winsound
模块提供对由 Windows 平台提供的基本声音播放机制的访问。它包括一些函数和几个常量。
winsound.
Beep
(
frequency
,
duration
)
¶
哔哔 PC 扬声器。
frequency
参数指定声音的频率 (以赫兹为单位),且必须在 37 到 32,767 范围内。
duration
参数指定声音应该持续的毫秒数。若系统不能哔哔扬声器,
RuntimeError
被引发。
winsound.
PlaySound
(
sound
,
flags
)
¶
调用底层
PlaySound()
函数从平台 API。
sound
参数可以是文件名、系统声音别名、音频数据如
像字节对象
,或
None
. Its interpretation depends on the value of
flags
, which can be a bitwise ORed combination of the constants described below. If the
sound
参数为
None
, any currently playing waveform sound is stopped. If the system indicates an error,
RuntimeError
被引发。
winsound.
MessageBeep
(
type=MB_OK
)
¶
调用底层
MessageBeep()
函数从平台 API。这播放如注册表中的指定声音。
type
自变量指定要播放的声音;可能的值是
-1
,
MB_ICONASTERISK
,
MB_ICONEXCLAMATION
,
MB_ICONHAND
,
MB_ICONQUESTION
,和
MB_OK
,所有描述见下文。值
-1
produces a “simple beep”; this is the final fallback if a sound cannot be played otherwise. If the system indicates an error,
RuntimeError
被引发。
winsound.
SND_ALIAS
¶
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
.
所有 Win32 系统至少支持以下;大多数系统支持更多:
PlaySound()
name
|
相应的控制面板声音名称 |
|---|---|
'SystemAsterisk'
|
星号 |
'SystemExclamation'
|
感叹号 |
'SystemExit'
|
退出 Windows |
'SystemHand'
|
严重错误停止 |
'SystemQuestion'
|
询问 |
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
¶
重复播放声音。
SND_ASYNC
flag must also be used to avoid blocking. Cannot be used with
SND_MEMORY
.
winsound.
SND_MEMORY
¶
sound
parameter to
PlaySound()
is a memory image of a WAV file, as a
像字节对象
.
注意
This module does not support playing from a memory image asynchronously, so a combination of this flag and
SND_ASYNC
会引发
RuntimeError
.
winsound.
SND_PURGE
¶
停止播放指定声音的所有实例。
注意
现代 Windows 平台不支持此标志。
winsound.
SND_ASYNC
¶
立即返回,允许异步播放声音。
winsound.
SND_NODEFAULT
¶
若找不到指定声音,不播放系统默认声音。
winsound.
SND_NOSTOP
¶
不中断目前播放的声音。
winsound.
SND_NOWAIT
¶
立即返回,若声音驱动程序繁忙。
注意
现代 Windows 平台不支持此标志。
winsound.
MB_ICONASTERISK
¶
播放
SystemDefault
声音。
winsound.
MB_ICONEXCLAMATION
¶
播放
SystemExclamation
声音。
winsound.
MB_ICONHAND
¶
播放
SystemHand
声音。
winsound.
MB_ICONQUESTION
¶
播放
SystemQuestion
声音。
winsound.
MB_OK
¶
播放
SystemDefault
声音。
