Ticking in My WAV File

I am trying to make a tone file and it is working. but it is not sounding the way I want it to sound. There is a low tone beat in the file. that I did not add to it. And I do not know why it is there..

Someone told me to try fading out / fade in and not just going down to 0 and I did but it did not work.

can anyone help me ?

I just need to remove the ticking and output the right Frequency

here is my code:

tone = new isochronicTone(); tone.SetWaveFormat(44100, 2);

double time = Convert.ToDouble(time2.Text) / 2.2675;

time = time * 50000D; double Amplitude = Convert.ToDouble(Peaktxt.Text);

SaveFileDialog save1 = new SaveFileDialog();

save1.Filter = "Wave file (*.wav)|*.wav;";

if (save1.ShowDialog() != DialogResult.OK) return;

WaveFileWriter wavefile;

wavefile = new WaveFileWriter(save1.FileName, tone.WaveFormat);

double counter3 = 0;

double tenp = 0;

double Ptemp = Peak3 - 0.001D;

int newcounter = 0;

if (Beat3 != 0)

{

Beat3 = (1 / Beat3);

tenp = Beat3/(1D / 44100D);

}

else

{

Beat3 = 0;

}

for (int n = 0; n < time; n++)

{

if (counter3 >= Beat3 && Beat3 != 0)

{

for (int t = 0; t < tenp; t++)

{

if (Ptemp > 0.000005)

{

float temo = (float)(Ptemp * Math.Sin((((Math.PI * n * (Frequency3))/2) / 44100D)));

wavefile.WriteSample(temo);

wavefile.WriteSample(temo);

n++;

Ptemp = Ptemp - 0.001D;

newcounter++;

}

else if ((tenp - newcounter) <= 0 )

{

float temo = (float)(Ptemp * Math.Sin((((Math.PI * n * (Frequency3))/2) / 44100D)));

wavefile.WriteSample(temo);

wavefile.WriteSample(temo);

n++;

Ptemp = Ptemp + 0.001D;

}

else

{

wavefile.WriteSample(0F);

wavefile.WriteSample(0F);

n++;

}

}

counter3 = 0;

}

else

{

float temo = (float)(Peak3 * Math.Sin(((( Math.PI * n * (Frequency3))/2)/44100D))); wavefile.WriteSample(temo);

wavefile.WriteSample(temo);

counter3 = counter3 + (1D / 44100D);

Ptemp = Peak3 - 0.001D; newcounter = 0;

}

}

wavefile.Flush();

wavefile.Dispose();

if (waveout == null)

{

waveout = new WaveOut();

waveout.PlaybackStopped += onPlaybackStopped;

}

MixingSampleProvider mixer = new MixingSampleProvider(WaveFormat.CreateIeeeFloatWaveFormat(44100,2)); audioFileReader = new AudioFileReader(save1.FileName); mixer.AddMixerInput((ISampleProvider)audioFileReader);

SampleToWaveProvider mixer3 = new SampleToWaveProvider(mixer);

try {

waveout.Init(mixer3);

waveout.Play();

} catch

{

MessageBox.Show(" Error retry");

waveout.Stop();

waveout.Dispose();

waveout = null;

return;

}

What am i doing wrong ?

here is how it sounds:
