It does not. At least in my 3.0 version. Is there some package or another tool to make something like this with sound ?

An example of a channel is a : pipe, and this surely works on Unix versions of Mathematica. : If you have either PBMPlus or netPBM installed on your system, : try something like this: : Plot[Sin[x], {x,0,2Pi}, : DisplayFunction :> ( : Display["!pnmsmooth | ppmtogif > testme.gif", #, "PBM"]&)] : The plot is fed into psrender, which converts the graphic to a : portable bitmap. It is then piped through two of the filter tools : from the above toolkits to create a somewhat blurred gif. : I believe that you can also use an OutputStream[] as a channel. : -- : P.J.
