What Everyone Ought To Know About AMONG US

In the online video game Among Us, players that check out the Comms area hear a fuzzy sound recording of a collection of piercing beeps that sound like Morse code. I first listened to the recording below, however this more recent video additionally plays it at around 5:00, complied with by a great description of the issue with trying to decode the code.

The adhering to figure reveals a spectrogram of the audio clip, with time on the x-axis, as well as each upright piece showing the Fourier transform of a brief (roughly 50 ms) moving home window of the signal focused at the equivalent time. We can plainly see the "dots" as well as "dashes" at around 1 kHz, with the corresponding translation overlaid in yellow.

Since we have the Morse code drawn out from the sound (which, for referral if you wish to copy-paste and also play with this problem, is ".-.-- ...-.-- ...-. -..."), we simply need to translate it, right? The trouble is that the dots as well as dashboards are all consistently spaced, without the required longer voids between letters, let alone the still longer voids that would be expected between words. Without understanding the intended areas of those voids, the code is unclear: for example, the first dot can indicate the letter E, or the initial dot and dash with each other could suggest an A, etc

. That turns out to be a large issue. The adhering to figure shows the translating trie for Morse code letters as well as digits; starting at the root, move to the left kid vertex for every dot, or to the ideal child vertex for every dashboard. A red vertex suggests either an invalid code or various other punctuation.


Morse code represented as a deciphering trie; each left as well as best side shows a dot or dashboard, specifically.
If we neglect the numbers in the most affordable degree of the trie, we see that not just are Morse code letters uncertain (i.e., not prefix-free), they are almost "maximally ambiguous," in the sense that the trie of letters is almost full. That is, for almost any prefix of 4 dashes and dots we may encounter, the space showing the end of the first letter could be after any of those very first 4 icons.

This would certainly make a wonderful programming workout for trainees, to show that this certain sequence of 24 symbols may be deciphered into a series of letters in specifically 3,457,592 feasible methods. Given, the majority of these decodings lead to rubbish, like AEABKGEAEAEEE. But a much more challenging as well as interesting trouble is to effectively search for sensible decodings, that is, messages including actual (English?) words, maybe furthermore constricted by grammatical links between words.

Obviously, it's also feasible-- likely?-- that this audio clip is simply made up, a random sequence of dashes and dots meant to sound like "real" Morse code. As well as even if it's not, we may not have the ability to discriminate. Which is the intriguing question that motivated this post: if we produce an entirely random, and also therefore purposefully muddled, series of 24 dots as well as dashboards, what is the possibility that it still produces a "sensible" feasible decoding, for sufficiently big worths of "affordable"?


Now that we have the Morse code extracted from the sound (which, for reference if you want to copy-paste and also play with this problem, is ". Without understanding the intended locations of those spaces, the code is uncertain: for example, the very first dot might indicate the letter E, or the very first dot as well as dash together might indicate an A, etc

. The following number reveals the deciphering trie for Morse code letters and numbers; starting at the origin, move to the left youngster vertex for each dot, or to the right child vertex for each dash.-- that this audio clip is just made up, a random series of dashboards as well as dots indicated to sound like "real" Morse code.
