\versionadded{1.5.2}
|
|
|
|
The \module{winsound} module provides access to the basic
|
|
sound-playing machinery provided by Windows platforms. It includes
|
|
two functions and several constants.
|
|
|
|
|
|
\begin{funcdesc}{Beep}{frequency, duration}
|
|
Beep the PC's speaker.
|
|
The \var{frequency} parameter specifies frequency, in hertz, of the
|
|
sound, and must be in the range 37 through 32,767 (\code{0x25}
|
|
through \code{0x7fff}). The \var{duration} parameter specifies the
|
|
number of milliseconds the sound should last. If the system is not
|
|
able to beep the speaker, \exception{RuntimeError} is raised.
|
|
\versionadded{1.5.3} % XXX fix this version number when release is scheduled!
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{PlaySound}{sound, flags}
|
|
Call the underlying \cfunction{PlaySound()} function from the
|
|
Platform API. The \var{sound} parameter may be a filename, audio
|
|
data as a string, or \code{None}. Its interpretation depends on the
|
|
value of \var{flags}, which can be a bit-wise ORed combination of
|
|
the constants described below. If the system indicates an error,
|
|
\exception{RuntimeError} is raised.
|
|
\end{funcdesc}
|
|
|
|
|
|
\begin{datadesc}{SND_FILENAME}
|
|
The \var{sound} parameter is the name of a WAV file.
|
|
\end{datadesc}
|
|
|
|
\begin{datadesc}{SND_ALIAS}
|
|
The \var{sound} parameter should be interpreted as a control panel
|
|
sound association name.
|
|
\end{datadesc}
|
|
|
|
\begin{datadesc}{SND_LOOP}
|
|
Play the sound repeatedly. The \constant{SND_ASYNC} flag must also
|
|
be used to avoid blocking.
|
|
\end{datadesc}
|
|
|
|
\begin{datadesc}{SND_MEMORY}
|
|
The \var{sound} parameter to \function{PlaySound()} is a memory
|
|
image of a WAV file.
|
|
|
|
\strong{Note:} This module does not support playing from a memory
|
|
image asynchonously, so a combination of this flag and
|
|
\constant{SND_ASYNC} will raise a \exception{RuntimeError}.
|
|
\end{datadesc}
|
|
|
|
\begin{datadesc}{SND_PURGE}
|
|
Stop playing all instances of the specified sound.
|
|
\end{datadesc}
|
|
|
|
\begin{datadesc}{SND_ASYNC}
|
|
Return immediately, allowing sounds to play asynchronously.
|
|
\end{datadesc}
|
|
|
|
\begin{datadesc}{SND_NODEFAULT}
|
|
If the specified sound cannot be found, do not play a default beep.
|
|
\end{datadesc}
|
|
|
|
\begin{datadesc}{SND_NOSTOP}
|
|
Do not interrupt sounds currently playing.
|
|
\end{datadesc}
|
|
|
|
\begin{datadesc}{SND_NOWAIT}
|
|
Return immediately if the sound driver is busy.
|
|
\end{datadesc}
