 public NAudio.Wave.WaveIn input = null;
        public NAudio.Wave.DirectSoundOut waveout = null;
        public NAudio.Wave.WaveInProvider wavein = null;
       
        private void button1_Click(object sender, EventArgs e)
        {

            WaveIn input = new NAudio.Wave.WaveIn();
            input.WaveFormat = new NAudio.Wave.WaveFormat(44100, 2);
            IWaveProvider wavein = new NAudio.Wave.WaveInProvider(input);
       
            waveout = new NAudio.Wave.DirectSoundOut();
            waveout.Play();
