Play a sound during a state transition

Question

Greetings,
I would like to associate a sound with a transition so that it is played during the duration of the transition.
What is the best way to do that in flex Hero?
Thank you.

You might find the SoundEffect class useful, for example:
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
          xmlns:s="library://ns.adobe.com/flex/spark"
          xmlns:mx="library://ns.adobe.com/flex/mx"
          title="Sound Effect">
     <s:states>
          <s:State name="state1"/>
          <s:State name="state2"/>
     </s:states>
     <s:actionContent>
          <s:Button label="toggle state" click="currentState=currentState=='state1'?'state2':'state1'" />
     </s:actionContent>
     <s:transitions>
          <s:Transition fromState="*" toState="*">
               <s:Parallel>
                    <s:Parallel target="{target}">
                         <s:Fade />
                         <mx:SoundEffect duration="1000" source="mySound.mp3"/>
                    </s:Parallel>
               </s:Parallel>
          </s:Transition>
     </s:transitions>
     <s:Button id="target" label="target" width="100" height="100" verticalCenter="0" horizontalCenter="0"
                 alpha.state1="1" alpha.state2="0.5"/>
</s:View>
