To achieve draw waveform from output sounds

public void OnDataAvailable(object sender, WaveInEventArgs e)

{

_writer.Write(e.Buffer, 0, e.BytesRecorded);

//byte[] waveData = new byte[100 * Bytes_Per_Sample1];

//short low = 0;

//short high = 0;

//stream.Read(waveData, 0, waveData.Length);

//for (int n = 0; n < waveData.Length; n += 8)

//{

// short sample = BitConverter.ToInt16(waveData, n);

// if (sample < low) low = sample;

// if (sample > high)

// high = sample;

//}

//float lowPercent = ((((float)low) - short.MinValue) / ushort.MaxValue);

//float highPercent = ((((float)high) - short.MinValue) / ushort.MaxValue);

//g.DrawLine(Draw_lIne, d, Wave_Control_Main_Player.Height * lowPercent, d, Wave_Control_Main_Player.Height * highPercent);

//d++;

//if (d == Wave_Control_Main_Player.Width)

//{

// Wave_Control_Main_Player.Invalidate();

// d = 0;

//}
