actionscript 3 - add equalizer for online flash radio -

i have tried add equalizer online radio. used http://www.everyday3d.com/blog/index.php/2008/03/26/classic-sound-equalizer-in-flashas3/

flash source file . it's working fine when worked in flash ide. on server equalizer doesnot show. if playing file mp3 format worked if play stream url it's not working. dont know how can fix this. using as3, new flash. please one. advance

the equalizer code

 var es:equalizersettings = new equalizersettings();             es.numofbars = 80;             es.height = 30;             es.barsize = 3;             es.vgrid = true;             es.hgrid = 2;             es.colormanager = new gradientbarcolor(0xffff4444);             es.effect = equalizersettings.fx_reflection;              var e:equalizer = new equalizer();             e.update(es);             e.x = 100;             e.y = 60;             addchild(e);              addeventlistener(event.enter_frame, e.render); 

what gio said, soundmixer.computespectrum-based approach, such 1 linked in question, suffers security problems. there alternatives, example check code: http://wonderfl.net/c/euib/read (some of stream urls in dead, , might not work right away - try own stream url)
