            addEventListener(Event.ENTER_FRAME, e.render);

You're probably getting a `SecurityError` which can't be seen because you're probably running your Flash content in a non-debugger player. This will happen if you're streaming from another domain. If this is the case you'll need a cross-domain.xml. Read more [HERE](http://www.adobe.com/devnet/articles/crossdomain_policy_file_spec.html) — Gio, Jul 19 '13 at 12:20
i did not get any SecurityError. my only problem is my radio player working fine but the equalizer only not showing when the radio play. — Moovendra Dhinesh babu, Jul 19 '13 at 13:05
Sorry I couldn't catch this. You should post your code where you display the equalizer so we can help. — Gio, Jul 19 '13 at 14:13
It's still not visible in your posted code what method are you using for the equalizer. Most interesting part is in the `Equalizer` class itself. So your posted code doesn't help. As @makc said, I also think that you're using `SoundMixer.computeSpectrum()` method. — Gio, Jul 20 '13 at 07:29

What Gio said, SoundMixer.computeSpectrum-based approach, such as the one linked in your question, suffers from security problems. But there are alternatives, for example check this code: http://wonderfl.net/c/euIb/read (some of stream URLs in it are dead, and it might not work right away - so try it with your own stream URL)
