The volume element changes the volume of the audio data.
gst-launch -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.
