The ending song of an anime television series called Le Eden de la Grisaia here has a light flashing. I suspect it may be Morse Code. By watching the video a little more slowly than usual (frame by frame), it's easy to see that
- dit is 2 frames
- dah is 6 frames
- intra-character gap is 2 frames
- gap between characters is 6 frames
- gap between words is 14 frames
So it probably is Morse Code.
I've managed to translate it into letters. Here's my recording of the transmission. -
means the light is on. means the light is off.
At the beginning:
--- - --- - --- --- - --- --- - --- - --- --- - --- --- --- - - - --- - - - --- -
Which is "CQ CQ GE EDEN". Notice there is only 1 dit's time between "C" and "Q".
And at around 1:25:
--- - - --- - -
Which is "DD".
I haven't used Morse Code before, so I don't know what these letters mean. What do they mean?
EDIT:
Thanks to to a comment by Phil Frost. The TV show is Japanese. I looked up the Japanese equivalent of Morse Code, Wabun Code. If it's in Wabun Code, the transmission would be
リヘ ヘホヘタ
and
ホホ
Unfortunately, I don't know Japanese. So if anyone who sees this happens to know Japanese, please tell me whether the above makes any sense. Googling yielded no results.
