To what does zero crossing refer?
A) Self-contained audio regions that are recorded and then cut, trimmed and tested to make sure they do not skip
B) When the end of the loop and the beginning of the loop cross the exact center of the waveform where the volume of the wave is essentially zero
C) Prevents loops that skip
D) Forces a switch to Ogg

Zero crossing refers to the point in a waveform where the amplitude of the signal is zero or crosses the x-axis. In the context of looping audio, zero crossing is used to ensure that there are no pops, clicks or other disruptions in the loop when it is played back. The most seamless point to loop a waveform is at the exact center where the volume is essentially zero, which is why zero crossing is important.
