The audiomixer allows to mix several streams into one by adding the data. Mixed data is clamped to the min/max values of the data format.
Unlike the adder element audiomixer properly synchronises all input streams.
The input pads are from a GstPad subclass and have additional properties to mute each pad individually and set the volume:
