The notion that cutting at the zero crossing of a waveform will eliminate pops 
is a myth that won't die. You'll see it in books and DAW manuals and offered as 
a feature in some DAWs. 

Cutting a waveform at the zero crossing will reduce pops, but certainly not 
eliminate them. Try cutting a short burst of, say, 100 Hz sine wave at the zero 
crossings. You'll hear a pop at each end.

My standard technique is to make all audio cuts crossfades. It's easy in a DAW. 
15 ms is usually enough, 30 ms will be smooth. Try it.
