Alright, so my last post claimed that the sound strings that the obelisks emit are time-aligned. It since then has turned out that while yes they mostly are time-aligned, it seems to have no importance. After even more inspection, I *finally* noticed that there are only 7 different tokens, which are demonstrated below.
At first I thought that L3 also had a variant, which I named L4 and I was already jumping with joy, because base8 numbers fit exactly into 3 binary bits (note the number 3), which would have made a huge amount of sense... alas, it was not to be and I can confirm that indeed there are only the 7 tokens + the [END] block which always stays the same.
So with those tokens we can divide the messages like shown below:
The above string would be: SL1VL2L1SBSBL3L2VL1L2BL3VBHL2L3HL1VHBL1L2L3S[END]
It is interesting to note that my rule about there never being 2 tokens of the same type in a row still holds true! So, CMDR Farran speculated that perhaps it is indeed a language. We know that the Guardians used sign language to communicate, making two of the same sign in a row makes no sense, right? so naturally you can't have 2 tokens in a row... in addition, 7 gestures of some sort can be arranged into strings of gestures/tokens - aka. words! So we think that the strings transmitted by the obelisks are indeed words (or even sentences). So, now we definitely need some linguistics people working on this!
EDIT: I will post the strings I have tokenized -
