+/*!
+    \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(), supportedChannels(), supportedCodecs(),
+    supportedFrequencies(), 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().
+
+    A QAudioDeviceInfo is constructed with a QAudioDeviceId, which is
+    an identifier for a physical device. It is used by Qt to construct
+    classes that communicate with the device--such as
+    QAudioDeviceInfo, QAudioInput, and QAudioOutput. The static
+    functions defaultInputDevice(), defaultOutputDevice(), and
+    deviceList() let you get a hold of the ids for all available
+    devices. You fetch ids based on whether you will use the device
+    for input or output; this is specified by the QAudio::Mode enum.
+    The QAudioDeviceId returned are only valid for the QAudio::Mode.
+
+    For instance:
+
+    \code
+    foreach(QAudioDeviceId audioId, QAudioDeviceInfo::deviceList(QAudio::AudioOutput)) {
+        QAudioDeviceInfo info(audioId);
+        qDebug() << "Device name: " << info.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, QAudioDeviceId

+    \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 Frequency
+            \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)
+        \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.

+    \class QAudioInput
+    \brief The QAudioInput class provides an interface for receiving audio data from an audio input device.
+
+    \inmodule QtMultimedia
+    \ingroup  multimedia
+    \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 QAudioDeviceId. When you create the audio input, you
+    should also send in the QAudioFormat to be used for the recording
+    (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 QAudioDeviceId 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:
+
+    \code
+    {
+      QFile outputFile;
+      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);
+
+      QAudioInput *audio = new QAudioInput(format, this);
+      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();
+    }
+    \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 totalTime()
+    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 clock() 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.

+/*!
+    \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 QAudioDeviceId. 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;
+      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);
+
+      QAudioOutput *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();
+        }
+      }
+    \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, clock() 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.
+
+    If an error is encountered state changes to QAudio::StopState.
