The winsound module provides access to the basic
sound-playing machinery provided by Windows platforms. It includes
functions and several constants.
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.
Note:
Under Windows 95 and 98, the Windows Beep()
function exists but is useless (it ignores its arguments). In that
case Python simulates it via direct port manipulation (added in version
2.1). It's unknown whether that will work on all systems.New in version 1.6.
PlaySound(
sound, flags)
Call the underlying PlaySound() function from the
Platform API. The sound parameter may be a filename, audio
data as a string, or None. Its interpretation depends on the
value of flags, which can be a bit-wise ORed combination of
the constants described below. If the system indicates an error,
RuntimeError is raised.
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.
New in version 2.3.
SND_FILENAME
The sound parameter is the name of a WAV file.
Do not use with SND_ALIAS.
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
For example:
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)
SND_LOOP
Play the sound repeatedly. The SND_ASYNC flag must also
be used to avoid blocking. Cannot be used with SND_MEMORY.
SND_MEMORY
The sound parameter to PlaySound() is a memory
image of a WAV file, as a string.
Note:
This module does not support playing from a memory
image asynchronously, so a combination of this flag and
SND_ASYNC will raise RuntimeError.
SND_PURGE
Stop playing all instances of the specified sound.
SND_ASYNC
Return immediately, allowing sounds to play asynchronously.
SND_NODEFAULT
If the specified sound cannot be found, do not play the system default
sound.
