Apollo 11 landing audio as it sounded on Eagle

Most of the time when we listen to the Apollo 11 landing, we listen to it as we it was heard on earth with CAPCOM (Charles Duke) in Houston responding immediately to communications from Apollo at the moon -- but relativity dictates that there are three humans who heard it with different timing. At the moon, 3 astronauts heard themselves immediately responding to CAPCOM, with a 2.55 second delay from earth.
I wanted to hear what it sounded like on the moon, so I took a recording of the CAPCOM/Apollo communication, and carefully separated the Apollo communications from the ground chatter. Then I shifted the ground loop 2.55 seconds back so that I could hear things from the Apollo point of view.
This is about 5 minutes of that time-shifted recording -- from the final go-nogo landing check to just after the first stay/no-stay check.
The left track is the shifted Houston/Apollo audio track. The right track is the Flight Director (Gene Krantz) audio track.

One thing jumps out with this new timing. Neil almost failed to say "Tranquillity base here, The Eagle Has Landed". Once they touch down (3:42), they immediately go into the post-touchdown checklist, until Duke prompts Neil with "We copy you are down" (3:56). Neil almost immediately responds with his famous words.
This raises another issue for me. The "People turning blue" conversation indicates that Neil's famous words are a coded transmission meant to indicate "We're on the moon, and all seems OK". I can see there having been at least four versions of that transmission:
Touchdown, all is good
We touched down but immediately aborted.
We landed, but can't stay, and (most dire)
We landed but can't leave.

If anybody who sees this can reach someone who still remembers, I have a question:
What were the possible utterances for Neil, and what would they have meant?

I hear Neil starting to say "Houston, ..." as Charlie says "We copy you down Eagle" then Neil continues "Tranquility base..." Neil was already saying 'Houston, tranquility base here' etc when Charlie starts to comment. Neil and Buzz had to perform a few things after landing before transmitting back to earth. Then when that was done Neil officially radioed to say they landed to mission control. There was no prompting needed.

Also there is not a 2.55 second delay. Speed of light from the moon to earth is about 1.3 seconds (one way). You dont need 2-way time lag when one side or the other was recording it.

People turning blue just said everyone in mission control knowing fuel was getting real low where 'holding their breath' as an expression they were excited, anxious, or nervous about those last few moments. There was no coded message. Then you hear Gene announce T1 was approaching...the Stay or No stay status call.

Unfortunately, your edit to show what things sounded like from the point of view of the Apollo crew, is fundamentally flawed.

Remember, throughout the entire mission, the ONLY voice the astronauts heard, was CapCom's.. which role, at the time of landing, was being filled by Charlie Duke. ALL the other Mission Control chatter, the go/no-goes, the program alarm discussions, and even Gene Kranz himself, COULD NOT BE HEARD by the astronauts.

A truly accurate astronaut's POV recording, should only include Charlie's, Neil's, and Buzz's voices.
