+    \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.
