volume

The volume element changes the volume of the audio data.

Example launch line

 gst-launch-1.0 -v -m audiotestsrc ! volume volume=0.5 ! level ! fakesink silent=TRUE

This pipeline shows that the level of audiotestsrc has been halved (peak values are around -6 dB and RMS around -9 dB) compared to the same pipeline without the volume element.

Properties

mute 

“mute” gboolean

mute channel

Flags : Read / Write

Default value : false

volume 

“volume” gdouble

volume factor, 1.0=100%%

Flags : Read / Write

Default value : 1

volume-full-range 

“volume-full-range” gdouble

The volume-full-range factor is a range from 0.0 to G_MAXDOUBLE so it is very inclusive, e.g. gain of +48 dB is very reasonable. This property allows setting higher value than the volume property.

Flags : Read / Write

Default value : 1

Since : 1.24
