title: Create an Audio Graphic Equalizer for Windows
body: <p>I need to create an <strong>audio graphic equalizer</strong> with the commonly used <strong>presets</strong>, for an application in Windows. I need to <strong>apply the equalization effects globally</strong> across all applications in Windows (ex DFX audio enhancer v11.1 applies effects at system level). </p>
  
  <p>Currently I can get to the frames of the system audio using sAPO samples provided by Microsoft. But I need to apply graphic equalization to this.</p>
  
  <p>Does Microsoft provides <strong>any API or Sample code</strong> for creating graphic equalizer in Windows?</p>
  
  <p>Kindly inform me if there are any <strong>other Libraries or Open Source</strong> project that I can use for this purpose.</p>
