    How do you get the visualization from an audio file in WinRT? Are there any libraries? Thx!

      Hi,

      At first I was using NAudio for that ( http://naudio.codeplex.com/ ) and there’s a tutorial attached, but it failed the Store certification.

      So now I’m using FMODex ( http://www.fmod.org/ ) which is working for WinRT.
      Once you play a sound using FMOD you can retrieve the spectrum like this:
      // Get for the left and right channels
      var a1 = music._channel.getSpectrum(levelsBufferRight, levelsBufferRight.Length, 0, FMOD.DSP_FFT_WINDOW.HAMMING);
      var a2 = music._channel.getSpectrum(levelsBufferLeft, levelsBufferLeft.Length, 1, FMOD.DSP_FFT_WINDOW.HAMMING);

      Then it’s all about tweaking the result to make it look “nice”.
