Okay, so i did the sound analysis of "listen to my voice" and here is what i got.
The whole sound looks like this: https://hkar.ru/OTR4
It doesn't make any image, but if you look at both ends of the spectogram you can see a difference with the rest of the picture.
So i enhanced both ends and here is what i got
Left end https://hkar.ru/OTR2
Left end with different settings: https://hkar.ru/OTR3
Right end:https://hkar.ru/OTR1
Right end with different settings: https://hkar.ru/OTR0
Okay now... the right end looks like morse code, but it is not apparent with the letters spacing. It could be treated as several different letters.
I didn't find anything that I could decypher at this point.

EDIT1
the hypno - 467767 description reminded me of an SCP article. The way some information is blanked out and the way and the style it is written with.
Example (best in the end)
http://www.scp-wiki.net/scp-028
Maybe there is a speciment of SCP connected with those numbers-467767 or with "horror"? Or with mental house?
Those "attachments" such as "1b" or "1a" mentioned are used in SCPS descriptions as well. They usually mean either part of a speciment (for example copy's of the main speciment that he produces himself are 1a, 1b etc. or it could mean some protocol of testing. Like dialog with the person who was exposed to SCP, or dialog with doctor, or dialog with the speciment itself.
Also I. SCP they usually use people from class D, which stands for the lowes class. Those are usually insane, or murderers. And the Hypno description uses the word "inmate" which is interesting and also corresponds to SCP lore
