If you examine the waveform in Audacity (which you should put on your 
PC as well) you might see that it doesn't start and end at the 
baseline. You can cure that in code, or you can just use Audacity to 
trim off a few samples so that the waveform begins at 0.

Alternatively, select the first few cycles and apply a "fade in" 
effect. The same at the tail, with "fade out".
