Two pops after the last frame are commonly called what?

• A. Tail Pop
• B. Wordclock
• C. Main Clock
• D. Wild

Answer: (A)

The idea being tested is recognizing a specific audio artifact that happens at the very end of a clip. When the last frame ends, an abrupt truncation or a quick, transient discontinuity can create a short, noticeable pop: the tail of the audio is left with a tiny impulse. This is what is meant by a tail pop. Seeing two pops after the final frame fits this label because the artifact appears at the tail end of the piece, once the frame data has stopped, producing those little audible blips.

Wordclock, Main clock, and Wild describe things related to equipment timing or terminology that aren’t about audible end-of-clip artifacts. Wordclock and Main clock refer to synchronization signals or timing references in digital audio, while Wild isn’t a standard term for this phenomenon.
