I need to build an audio player control that shows a graphical representation of the audio data. Something that will allow users to identify periods of silence. To do this I need to access the audio sample data.

You might try taking a look at Pete Brown's Silverlight Synthesizer project. I believe it has the audio feedback when the sounds play.

Hi,
Are you saying you want to get a snapshot of the video you want to play. If this is the case , you may try this:
WriteableBitmap wb = new WriteableBitmap(mp, null); //mp is my MediaElement img.Source = wb; //img is my image control
Best Regards

Thanks Bryant, After looking at a few samples (including Pete Brown's Silverlight Synthesizer) and articles the only way I could do it was by actually writing my own decoder and using the MediaStreamSource class. Unfortunately I could not avoid writing decoder code– which was what I hoped initially.

I've had the same problem.
I've managed to port an old C# MP3 decoder to Silverlight 3 and have a working MP3 MediaStreamSource that outputs the raw sample data as well.
When it has been cleaned up (lots of old, unrequired code) I will post it at http://slaudiostreams.codeplex.com/
Hopefully this will be before the 30 days publishing limitation is up on CodePlex.
