-/*!
-    \class QAudioDeviceInfo
-    \brief The QAudioDeviceInfo class provides an interface to query audio devices and their functionality.
-    \inmodule QtMultimedia
-    \ingroup multimedia
-
-    \since 4.6
-
-    QAudioDeviceInfo lets you query for audio devices--such as sound
-    cards and USB headsets--that are currently available on the system.
-    The audio devices available are dependent on the platform or audio plugins installed.
-
-    You can also query each device for the formats it supports. A
-    format in this context is a set consisting of a specific byte
-    order, channel, codec, frequency, sample rate, and sample type.  A
-    format is represented by the QAudioFormat class.
-
-    The values supported by the the device for each of these
-    parameters can be fetched with
-    supportedByteOrders(), supportedChannelCounts(), supportedCodecs(),
-    supportedSampleRates(), supportedSampleSizes(), and
-    supportedSampleTypes(). The combinations supported are dependent on the platform,
-    audio plugins installed and the audio device capabilities. If you need a specific format, you can check if
-    the device supports it with isFormatSupported(), or fetch a
-    supported format that is as close as possible to the format with
-    nearestFormat(). For instance:
-
-    \snippet doc/src/snippets/audio/main.cpp 1
-    \dots 8
-    \snippet doc/src/snippets/audio/main.cpp 2
-
-    A QAudioDeviceInfo is used by Qt to construct
-    classes that communicate with the device--such as
-    QAudioInput, and QAudioOutput. The static
-    functions defaultInputDevice(), defaultOutputDevice(), and
-    availableDevices() let you get a list of all available
-    devices. Devices are fetch according to the value of mode
-    this is specified by the QAudio::Mode enum.
-    The QAudioDeviceInfo returned are only valid for the QAudio::Mode.
-
-    For instance:
-
-    \code
-    foreach(const QAudioDeviceInfo &deviceInfo, QAudioDeviceInfo::availableDevices(QAudio::AudioOutput))
-        qDebug() << "Device name: " << deviceInfo.deviceName();
-    \endcode
-
-    In this code sample, we loop through all devices that are able to output
-    sound, i.e., play an audio stream in a supported format. For each device we
-    find, we simply print the deviceName().
-
-    \sa QAudioOutput, QAudioInput

-    \class QAudioFormat
-    \brief The QAudioFormat class stores audio parameter information.
-
-    \inmodule QtMultimedia
-    \ingroup  multimedia
-    \since 4.6
-
-    An audio format specifies how data in an audio stream is arranged,
-    i.e, how the stream is to be interpreted. The encoding itself is
-    specified by the codec() used for the stream.
-
-    In addition to the encoding, QAudioFormat contains other
-    parameters that further specify how the audio data is arranged.
-    These are the frequency, the number of channels, the sample size,
-    the sample type, and the byte order. The following table describes
-    these in more detail.
-
-    \table
-        \header
-            \o Parameter
-            \o Description
-        \row
-            \o Sample Rate
-            \o Samples per second of audio data in Hertz.
-        \row
-            \o Number of channels
-            \o The number of audio channels (typically one for mono
-               or two for stereo)
-        \row
-            \o Sample size
-            \o How much data is stored in each sample (typically 8
-               or 16 bits)
-        \row
-            \o Sample type
-            \o Numerical representation of sample (typically signed integer,
-               unsigned integer or float)
-        \row
-            \o Byte order
-            \o Byte ordering of sample (typically little endian, big endian)
-    \endtable
-
-    You can obtain audio formats compatible with the audio device used
-    through functions in QAudioDeviceInfo. This class also lets you
-    query available parameter values for a device, so that you can set
-    the parameters yourself. See the QAudioDeviceInfo class
-    description for details. You need to know the format of the audio
-    streams you wish to play. Qt does not set up formats for you.

-    \since 4.6
-
-    You can construct an audio input with the system's
-    \l{QAudioDeviceInfo::defaultInputDevice()}{default audio input
-    device}. It is also possible to create QAudioInput with a
-    specific QAudioDeviceInfo. When you create the audio input, you

-    (see the QAudioFormat class description for details).
-
-    To record to a file:
-
-    QAudioInput lets you record audio with an audio input device. The
-    default constructor of this class will use the systems default
-    audio device, but you can also specify a QAudioDeviceInfo for a
-    specific device. You also need to pass in the QAudioFormat in
-    which you wish to record.
-
-    Starting up the QAudioInput is simply a matter of calling start()
-    with a QIODevice opened for writing. For instance, to record to a
-    file, you can:

-      QFile outputFile;   // class member.
-      QAudioInput* audio; // class member.
-    \endcode
-
-    \code
-    {
-      outputFile.setFileName("/tmp/test.raw");
-      outputFile.open( QIODevice::WriteOnly | QIODevice::Truncate );
-
-      QAudioFormat format;
-      // set up the format you want, eg.
-      format.setFrequency(8000);
-      format.setChannels(1);
-      format.setSampleSize(8);
-      format.setCodec("audio/pcm");
-      format.setByteOrder(QAudioFormat::LittleEndian);
-      format.setSampleType(QAudioFormat::UnSignedInt);
-
-      QAudioDeviceInfo info = QAudioDeviceInfo::defaultInputDevice();
-      if (!info.isFormatSupported(format)) {
-          qWarning()<<"default format not supported try to use nearest";
-          format = info.nearestFormat(format);

-      QTimer::singleShot(3000, this, SLOT(stopRecording()));
-      audio->start(&outputFile);
-      // Records audio for 3000ms
-    }
-    \endcode
-
-    This will start recording if the format specified is supported by
-    the input device (you can check this with
-    QAudioDeviceInfo::isFormatSupported(). In case there are any
-    snags, use the error() function to check what went wrong. We stop
-    recording in the \c stopRecording() slot.
-
-    \code
-    void stopRecording()
-    {
-      audio->stop();
-      outputFile->close();
-      delete audio;
-    }
-    \endcode
-
-    At any point in time, QAudioInput will be in one of four states:
-    active, suspended, stopped, or idle. These states are specified by
-    the QAudio::State enum. You can request a state change directly through
-    suspend(), resume(), stop(), reset(), and start(). The current
-    state is reported by state(). QAudioOutput will also signal you
-    when the state changes (stateChanged()).
-
-    QAudioInput provides several ways of measuring the time that has
-    passed since the start() of the recording. The \c processedUSecs()
-    function returns the length of the stream in microseconds written,
-    i.e., it leaves out the times the audio input was suspended or idle.
-    The elapsedUSecs() function returns the time elapsed since start() was called regardless of
-    which states the QAudioInput has been in.
-
-    If an error should occur, you can fetch its reason with error().
-    The possible error reasons are described by the QAudio::Error
-    enum. The QAudioInput will enter the \l{QAudio::}{StoppedState} when
-    an error is encountered.  Connect to the stateChanged() signal to
-    handle the error:
-
-    \snippet doc/src/snippets/audio/main.cpp 0
-
-    \sa QAudioOutput, QAudioDeviceInfo
-
-    \section1 Symbian Platform Security Requirements
-
-    On Symbian, processes which use this class must have the
-    \c UserEnvironment platform security capability.  If the client
-    process lacks this capability, calls to either overload of start()
-    will fail.
-    This failure is indicated by the QAudioInput object setting
-    its error() value to \l{QAudio::OpenError} and then emitting a
-    \l{stateChanged()}{stateChanged}(\l{QAudio::StoppedState}) signal.
-
-    Platform security capabilities are added via the
-    \l{qmake-variable-reference.html#target-capability}{TARGET.CAPABILITY}
-    qmake variable.

-/*!
-    \class QAudioOutput
-    \brief The QAudioOutput class provides an interface for sending audio data to an audio output device.
-
-    \inmodule QtMultimedia
-    \ingroup  multimedia
-    \since 4.6
-
-    You can construct an audio output with the system's
-    \l{QAudioDeviceInfo::defaultOutputDevice()}{default audio output
-    device}. It is also possible to create QAudioOutput with a
-    specific QAudioDeviceInfo. When you create the audio output, you
-    should also send in the QAudioFormat to be used for the playback
-    (see the QAudioFormat class description for details).
-
-    To play a file:
-
-    Starting to play an audio stream is simply a matter of calling
-    start() with a QIODevice. QAudioOutput will then fetch the data it
-    needs from the io device. So playing back an audio file is as
-    simple as:
-
-    \code
-      QFile inputFile;     // class member.
-      QAudioOutput* audio; // class member.
-    \endcode
-
-    \code
-      inputFile.setFileName("/tmp/test.raw");
-      inputFile.open(QIODevice::ReadOnly);
-
-      QAudioFormat format;
-      // Set up the format, eg.
-      format.setFrequency(8000);
-      format.setChannels(1);
-      format.setSampleSize(8);
-      format.setCodec("audio/pcm");
-      format.setByteOrder(QAudioFormat::LittleEndian);
-      format.setSampleType(QAudioFormat::UnSignedInt);
-
-      QAudioDeviceInfo info(QAudioDeviceInfo::defaultOutputDevice());
-      if (!info.isFormatSupported(format)) {
-          qWarning()<<"raw audio format not supported by backend, cannot play audio.";
-          return;
-      }
-
-      audio = new QAudioOutput(format, this);
-      connect(audio,SIGNAL(stateChanged(QAudio::State)),SLOT(finishedPlaying(QAudio::State)));
-      audio->start(&inputFile);
-
-    \endcode
-
-    The file will start playing assuming that the audio system and
-    output device support it. If you run out of luck, check what's
-    up with the error() function.
-
-    After the file has finished playing, we need to stop the device:
-
-    \code
-      void finishedPlaying(QAudio::State state)
-      {
-        if(state == QAudio::IdleState) {
-          audio->stop();
-          inputFile.close();
-          delete audio;
-        }
-      }
-    \endcode
-
-    At any given time, the QAudioOutput will be in one of four states:
-    active, suspended, stopped, or idle. These states are described
-    by the QAudio::State enum.
-    State changes are reported through the stateChanged() signal. You
-    can use this signal to, for instance, update the GUI of the
-    application; the mundane example here being changing the state of
-    a \c { play/pause } button. You request a state change directly
-    with suspend(), stop(), reset(), resume(), and start().
-
-    While the stream is playing, you can set a notify interval in
-    milliseconds with setNotifyInterval(). This interval specifies the
-    time between two emissions of the notify() signal. This is
-    relative to the position in the stream, i.e., if the QAudioOutput
-    is in the SuspendedState or the IdleState, the notify() signal is
-    not emitted. A typical use-case would be to update a
-    \l{QSlider}{slider} that allows seeking in the stream.
-    If you want the time since playback started regardless of which
-    states the audio output has been in, elapsedUSecs() is the function for you.
-
-    If an error occurs, you can fetch the \l{QAudio::Error}{error
-    type} with the error() function. Please see the QAudio::Error enum
-    for a description of the possible errors that are reported.  When
-    an error is encountered, the state changes to QAudio::StoppedState.
-    You can check for errors by connecting to the stateChanged()
-    signal:
