knob_id
file. These sliders control the transform object, or balance, of the sound file. For more
information, see the entry for Sound.setTransform(). Add the following ActionScript to your FLA
or AS file:
var my_sound:Sound = new Sound();
my_sound.loadSound("song1.mp3", true);
var transform_obj:Object = my_sound.getTransform();
this.createEmptyMovieClip("transform_mc", this.getNextHighestDepth());
transform_mc.createTextField("transform_txt",
transform_mc.getNextHighestDepth, 0, 8, 120, 22);
transform_mc.transform_txt.html = true;
var knob_ll:MovieClip = transform_mc.attachMovie("knob_id", "ll_mc",
transform_mc.getNextHighestDepth(), {_x:0, _y:30});
var knob_lr:MovieClip = transform_mc.attachMovie("knob_id", "lr_mc",
transform_mc.getNextHighestDepth(), {_x:30, _y:30});
var knob_rl:MovieClip = transform_mc.attachMovie("knob_id", "rl_mc",
transform_mc.getNextHighestDepth(), {_x:60, _y:30});
var knob_rr:MovieClip = transform_mc.attachMovie("knob_id", "rr_mc",
transform_mc.getNextHighestDepth(), {_x:90, _y:30});
knob_ll.top = knob_ll._y;
knob_ll.bottom = knob_ll._y+100;
knob_ll.left = knob_ll._x;
knob_ll.right = knob_ll._x;
knob_ll._y = knob_ll._y+(100-transform_obj['ll']);
knob_ll.onPress = pressKnob;
knob_ll.onRelease = releaseKnob;
