Who Else Wants To Be Successful With AMONG US

In the online game Among Us, players who visit the Comms room hear an unclear sound recording of a collection of shrill beeps that sound like Morse code. I initially heard the recording here, however this even more recent video also plays it at around 5:00, adhered to by a good explanation of the issue with attempting to decode the code.

The complying with figure reveals a spectrogram of the audio clip, with time on the x-axis, as well as each upright slice showing the Fourier transform of a brief (approximately 50 ms) gliding home window of the signal centered at the corresponding time. We can clearly see the "dots" as well as "dashes" at around 1 kHz, with the equivalent translation overlaid in yellow.

Currently that we have the Morse code drawn out from the audio (which, for recommendation if you want to copy-paste and play with this problem, is ". Without understanding the intended locations of those gaps, the code is unclear: for example, the first dot might indicate the letter E, or the initial dot and rush with each other could suggest an A, etc

. The adhering to figure reveals the translating trie for Morse code letters as well as digits; starting at the origin, step to the left kid vertex for each dot, or to the ideal youngster vertex for each dash.


Morse code represented as a decoding trie; each left as well as best edge indicates a dot or dashboard, respectively.
If we neglect the numbers in the most affordable degree of the trie, we see that not only are Morse code letters uncertain (i.e., not prefix-free), they are almost "maximally uncertain," in the sense that the trie of letters is almost complete. That is, for practically any type of prefix of four dashboards as well as dots we may experience, the gap suggesting completion of the very first letter might be after any of those initial four signs.

This would certainly make a nice programs workout for trainees, to show that this particular series of 24 symbols may be decoded into a series of letters in exactly 3,457,592 possible means. Granted, a lot of these decodings cause rubbish, like AEABKGEAEAEEE. A more challenging as well as interesting issue is to efficiently search for affordable decodings, that is, messages being composed of actual (English?) words, possibly furthermore constricted by grammatical links between words.

-- that this audio clip is just made up, an arbitrary sequence of dashes and also dots meant to sound like "genuine" Morse code. Which is the interesting concern that inspired this message: if we generate a totally arbitrary, and also hence purposefully muddled, series of 24 dots as well as dashes, what is the likelihood that it still produces a "affordable" possible decoding, for sufficiently big values of "reasonable"?


Now that we have the Morse code drawn out from the sound (which, for recommendation if you want to copy-paste as well as play with this trouble, is ". Without knowing the intended areas of those voids, the code is uncertain: for instance, the initial dot can indicate the letter E, or the initial dot and rush together might show an A, and so on

. The following number shows the deciphering trie for Morse code letters as well as digits; beginning at the origin, move to the left kid vertex for each dot, or to the ideal child vertex for each dash.-- that this audio clip is simply made up, a random sequence of dashes and dots indicated to appear like "real" Morse code.
