How is it possible to read and analyse the information found in real-time (e.g user soundtrack) audio in a way as to generate images based on it? (A visualizer of sorts) ..or do I have to resort to signal analysis, Fourier's transforms etc? I read something about Xaudio2 being capable of some low level magic but a) is this free or do I need an XDK proper? b) will it allow me to read the data I need? I also read something about FMOD in XDK, could someone explain this?
The closest you'll get in XNA is the VisualizationData class in the Microsoft.Xna.Framework.Media namespace. I can't speak to what exists in the real XDK for this.
many thanks mate, I looked it up on google and found a good deal of explanation on it. It looks like this is what I'll need after all=)
