Adding Individual Renderers

Renderers = new List<List<IRenderer>>()
{
  new List<IRenderer>() { new ColumnarType1Renderer() { GapRatio = 0.1f, Radius = 10f, HalfHeight = 0f, DataType = DataType.WAVE } }
};

Adding Multiple Renderers

Renderers = new List<List<IRenderer>>()
{
  new List<IRenderer>() { new ColumnarType1Renderer() { GapRatio = 0.1f, Radius = 10f, HalfHeight = 0f, DataType = DataType.WAVE } },
  new List<IRenderer>() { new ColumnarType1Renderer() { GapRatio = 0.1f, Radius = 10f, HalfHeight = 0f, DataType = DataType.WAVE } },
  new List<IRenderer>() { new ColumnarType1Renderer() { GapRatio = 0.1f, Radius = 10f, HalfHeight = 0f, DataType = DataType.WAVE } }
};

Adding Mixed Renderers

Renderers = new List<List<IRenderer>>()
{
  new List<IRenderer>(){
      new CircleRenderer() { Divisions = 6, Modulation = 1, Amplification = 1, Aggressive = 0.5f, ModulationStrength = 0.4f },
      new CircleBarRenderer() { Divisions = 8, Modulation = 2, Amplification = 1, Aggressive = 0.4f, ModulationStrength = 0.4f, DataType = DataType.WAVE },
      new LineRenderer() { ChangeColors = true, Color = Android.Graphics.Color.ParseColor("#cfa9d0fd"), FlashColor = Android.Graphics.Color.ParseColor("#FF6600"), Amplitude = 0.5f, DataType = DataType.WAVE }
    },
};

Settings Descriptions

• UseAndroidAudio (bool) - Listen to the system audio. If your device supports 0 as the session ID that will work right away. If you have to use SamsungSupport this requires using a BroadcastReceiver in your app to listen for the OPEN_AUDIO_EFFECT_CONTROL_SESSION events.
• SamsungSupport (bool) - If you have a device where passing 0 to the visualizer as the audio session does not work (error -3) try using true for this property.
• Renderers - A list of renderers to use for visuals
• Source - The source for the media player that is used. If you are not listening to system audio you can play media using the built in player.

Methods Descriptions

• .Play(); - Plays/Listens
• .Pause(); - Pauses the visualizer and media player
• .ChangeStyle() - Moves to the next style in the list
• .ChangeAudioSession() - Sets a specific audio session ID
