DESCRIPTION

       Access to the platform audio facilities.

       Qt provides the most commonly required audio operation in
       GUI applications: playing a sound file asynchronously to
       the user. This is most simply accomplished with a single
       call:

           QSound::play("mysounds/bells.wav");

       A second API is provided, where a QSound object is created
       from a sound file and is later be played:

           QSound bells("mysounds/bells.wav");
           bells.play();

       Sounds played by the second model may use more memory but
       play more immediately than sounds played using the first
       model, depending on the underlying platform audio
       facilities.

       On Microsoft Windows, the underlying multimedia system is
       used and hence WAVE format sound files are supported.

       On X11, the Network Audio System is used if available,
       otherwise all operations work silently. NAS supports WAVE
       and AU files.

       On Qt/Embedded, a built-in mixing sound server is used,
       which accesses /dev/dsp directly. Only a single WAVE
       format is supported, though that support can be configured
       when building Qt. The default is 11.025 kHz 8-bit mono
       PCM.

       QSound::available().


MEMBER FUNCTION DOCUMENTATION


QSound::QSound ( const QString & filename, QObject * parent=0,

       const char * name=0 )
       Constructs a sound which can quickly play the sound in
       file named filename.

       This can use more memory than the static play function.

       The parent and name arguments (default 0) are passed on to
       the QObject constructor.


QSound::~QSound ()

       Destructs the sound.


bool QSound::available () [static]

       Returns TRUE if sound facilities exist on the platform. An
       application may choose to notify the user if sound is
       crucial the the application, or operate silently without
       bothering the user.

       If no sound is available, QSound operation all work
       silently and quickly.


void QSound::play () [slot]

       Starts the sound playing. The function returns
       immediately. Depending on the platform audio facilities,
       other sounds may stop or may be mixed with the new sound.

       The sound can be played again at any time, possibly mixing
       or replacing previous plays of the sound.


void QSound::play ( const QString & filename ) [static]

       Play the sound in file named filename.
