I have a completely silence audio made from audacity. But when i convert it to wav 8bit/16bit and play it, it still plays some noise when the volume is max. So how to make a completely silence audio using audacity.

I have another audio where i have add few seconds of silence inbetween. I have converted that audio to wav 8bit/16bit. When i play the audio in full volume it still plays some noise.

Because i play the audio in android using audiotrack.write() it plays buzzing sound

The noise might be generated by the electronic equipment you are using to play the track, not by the digital file itself. There is always a bit of noise and it cannot be avoided completely. You can reduce it by buying more sophisticated headphones/sound cards, woofers etc.

Take a look at the Signal-To-Noise-Ratio concept. If there is no signal (silent track) at max volume it is easier to hear noise that otherwise is hidden by the signal.
