\class QSoundEffect
\brief The QSoundEffect class provides a way to play low latency sound effects.
\ingroup multimedia
\ingroup multimedia_audio
\inmodule QtMultimedia
This class allows you to play uncompressed audio files (typically WAV files) in
a generally lower latency way, and is suitable for "feedback" type sounds in
response to user actions (e.g. virtual keyboard sounds, positive or negative
feedback for popup dialogs, or game sounds). If low latency is not important,
consider using the QMediaPlayer class instead, since it supports a wider
variety of media formats and is less resource intensive.
This example shows how a looping, somewhat quiet sound effect
can be played:
\snippet multimedia-snippets/qsound.cpp 2
Typically the sound effect should be reused, which allows all the
parsing and preparation to be done ahead of time, and only triggered
when necessary. This assists with lower latency audio playback.
\snippet multimedia-snippets/qsound.cpp 3
Since QSoundEffect requires slightly more resources to achieve lower
latency playback, the platform may limit the number of simultaneously playing
sound effects.

\brief The SoundEffect type provides a way to play sound effects in QML.
\inmodule QtMultimedia
\ingroup multimedia_qml
\ingroup multimedia_audio_qml
\inqmlmodule QtMultimedia 5.0
SoundEffect is part of the \b{QtMultimedia 5.0} module.
This type allows you to play uncompressed audio files (typically WAV files) in
a generally lower latency way, and is suitable for "feedback" type sounds in
response to user actions (e.g. virtual keyboard sounds, positive or negative
feedback for popup dialogs, or game sounds). If low latency is not important,
consider using the MediaPlayer or Audio types instead, since they support a wider
variety of media formats and are less resource intensive.
Typically the sound effect should be reused, which allows all the
parsing and preparation to be done ahead of time, and only triggered
when necessary. This is easy to achieve with QML, since you can declare your
SoundEffect instance and refer to it elsewhere.
The following example plays a WAV file on mouse click.
