volume : qreal
This is the current loudness of the output.
(it is using Stevens' law to calculate the change in voltage internally).
Access functions:
qreal volume () const
void setVolume ( qreal newVolume )
Notifier signal:
void volumeChanged ( qreal newVolume )
See also volumeDecibel.
volumeDecibel : qreal
This is the current volume of the output in decibel.
0 dB means no change in volume, -6dB means an attenuation of the voltage to 50% and an attenuation of the power to 25%, -inf dB means silence.
Access functions:
qreal volumeDecibel () const
void setVolumeDecibel ( qreal newVolumeDecibel )
See also volume.
