This is based on the ms of audio data processed not on actual real-time. The resolution of the timer is platform specific.
Implements QAbstractAudioOutput.
Definition at line 124 of file qaudiodevicefactory.cpp.
Uses the device as the QIODevice to transfer data.
If device is null then the class creates an internal QIODevice. Returns a pointer to the QIODevice being used to handle the data transfer. This QIODevice can be used to write() audio data directly. Passing a QIODevice allows the data to be transferred without any extra code.
