yes. muting a stream panner means that it will send no signal to its
outputs. 

set_position()'s semantics vary depending on the concrete instance of
a StreamPanner. for a stereo panner, only the x value is of
significance, and it maps to a left/right position, normalized to
0..1, with 0=left.

if you use a Multi2dPanner, then the x + y axes are both used to
position the audio in a 2d plane.

i have not yet written a Multi3dPanner which would use x,y and z.
