00:00.000 --> 00:00.500
Silence before the recording enters.

00:00.500 --> 00:01.500
A synthetic pulse makes the bars appear.

00:01.500 --> 00:02.500
The quiet interval leaves the box clear.

00:02.500 --> 00:03.500
A softer pulse makes shorter bars.

00:03.500 --> 00:04.500
Another quiet interval.

00:04.500 --> 00:05.000
A louder pulse, then the final fade.
