title: Android: Global audio reverb effect
body: <p>I would like to add a reverb-effect on the global audio-out, which means I would like to modify the audio I can hear when I use any media-player.</p>
  
  <p>Sadly I found no working example, only some which applies the effect on an self-created MediaPlayer-instance.</p>
  
  <p>I tried this one, but none worked:</p>
  
  <pre><code>// try #1
  EnvironmentalReverb eReverb = new EnvironmentalReverb(1, 0);
  eReverb.setDecayHFRatio((short) 1000);
  eReverb.setDecayTime(10000);
  eReverb.setDensity((short) 1000);
  eReverb.setDiffusion((short) 1000);
  eReverb.setReverbLevel((short) 1000);
  eReverb.setReverbDelay(100);
  eReverb.setEnabled(true);
  
  // try #2
  PresetReverb mReverb = new PresetReverb(2,0);
  mReverb.setPreset(PresetReverb.PRESET_LARGEROOM);
  mReverb.setEnabled(true);
  </code></pre>
  
  <p>Can anyone help?</p>
