Question

The MediaPlayer.GetVisualizationData method does not work for Windows Phone 7, so I’m trying to find another way to visualize music playing through the MediaPlayer.

The post Extracting sound spectrum data in WP7 gives a method for doing beat detection given an audio buffer, but it doesn’t explain how to get this buffer on the phone.

How can I access audio samples/frequency data from the music MediaPlayer is playing? I’m not trying to access a buffer from the microphone – I need access to the output audio on the device.

“Visualization data is not available
on Windows Phone. Any attempt to get
visualization data on the phone will
populate the VisualizationData class
with 0s.”
