Property Documentation▲
device : AudioDevice▲
This property describes the audio device connected to this output.
The device property represents the audio device this output is connected to. This property can be used to select an output device from the QtMultimedia::MediaDevices::audioOutputs() list.
muted : bool▲
This property holds whether the audio output is muted.
Defaults to false.
volume : real▲
This property holds the volume of the audio output.
The volume is scaled linearly from 0.0 (silence) to 1.0 (full volume). Values outside this range will be clamped: a value lower than 0.0 is set to 0.0, a value higher than 1.0 will set to 1.0.
The default volume is 1.0.
UI volume controls should usually be scaled non-linearly. For example, using a logarithmic scale will produce linear changes in perceived loudness, which is what a user would normally expect from a volume control.
See QtMultimedia.convertVolume() for more details.
