New in version 1.5.2.
The winsound module provides access to the basic
sound-playing machinery provided by Windows platforms. It includes
functions and several constants.
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.
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.
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.
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
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.
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 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
# Play Windows exit sound.
# Probably play Windows default sound, if any is registered (because
# "*" probably isn't the registered name of any sound).
Play the sound repeatedly. The SND_ASYNC flag must also
be used to avoid blocking. Cannot be used with SND_MEMORY.
The sound parameter to PlaySound() is a memory
image of a WAV file, as a string.
This module does not support playing from a memory
image asynchronously, so a combination of this flag and
SND_ASYNC will raise RuntimeError.
Stop playing all instances of the specified sound.
Return immediately, allowing sounds to play asynchronously.
If the specified sound cannot be found, do not play the system default
Do not interrupt sounds currently playing.
Return immediately if the sound driver is busy.
