* @short_description: audio stereo pan effect
*
* <refsect2>
* Stereo panorama effect with controllable pan position.
* Stereo panorama effect with controllable pan position. One can choose between the default psychoacoustic panning method,
* which keeps the same perceived loudness, and a simple panning method that just controls the volume on one channel.
