Description

The adder allows to mix several streams into one by adding the data. Mixed data is clamped to the min/max values of the data format.

The adder currently mixes all data received on the sinkpads as soon as possible without trying to synchronize the streams.

Example launch line

1
gst-launch audiotestsrc freq=100 ! adder name=mix ! audioconvert ! alsasink audiotestsrc freq=500 ! mix.
This pipeline produces two sine waves mixed together.
