PySide.QtMultimedia.QAbstractAudioOutput.setNotifyInterval(milliSeconds)

Parameters:milliSeconds – PySide.QtCore.int

Sets the interval for PySide.QtMultimedia.QAbstractAudioOutput.notify() signal to be emitted. This is based on the ms of audio data processed not on actual real-time. The resolution of the timer is platform specific.

PySide.QtMultimedia.QAbstractAudioOutput.notifyInterval()

PySide.QtMultimedia.QAbstractAudioOutput.start(device)

Parameters:device – PySide.QtCore.QIODevice Return type:PySide.QtCore.QIODevice

Uses the device as the PySide.QtCore.QIODevice to transfer data. If device is null then the class creates an internal PySide.QtCore.QIODevice . Returns a pointer to the PySide.QtCore.QIODevice being used to handle the data transfer. This PySide.QtCore.QIODevice can be used to write() audio data directly. Passing a PySide.QtCore.QIODevice allows the data to be transferred without any extra code.

PySide.QtMultimedia.QAbstractAudioOutput.state()

Return type:PySide.QtMultimedia.QAudio.State

Returns the state of audio processing.

PySide.QtMultimedia.QAbstractAudioOutput.stateChanged(arg__1)

Parameters:arg__1 – PySide.QtMultimedia.QAudio.State

PySide.QtMultimedia.QAbstractAudioOutput.stop()

Stops the audio output.

PySide.QtMultimedia.QAbstractAudioOutput.suspend()

Stops processing audio data, preserving buffered audio data.
