sound proofing, so that no sound may leave the enclosure
I think this is a little redundant.
Audio recordings are to be kept at all hours from inside of the chamber.
I understand what you are saying, but it is phrased a little awkwardly. Maybe this would be better: "Audio from inside the chamber is to be recorded at all hours"?
kept on a 30 second delay with emergency cut-off
I'm not entirely sure what this means.
XXXX
Be consistent with formatting. SCP-XXXX is almost always used.
weighs in at
Off-tone.
lbs
Use metric.
As of yet
Off-tone in this usage, also you just used it like half a sentence ago so it is a little repetitive.
As of
Same.
We have yet to find a limit to storage capacity of SCP-XXXX, even after thousands of hours of recording with the device.
This is pretty much saying the exact same thing as the previous sentence.

Place commas where indicated.

However, it seems that asking direct questions leads to more targeted, if still random, results.
Put commas where indicated. Also kind of off-tone there but not overly so, so eh.
verbal response previously recorded
It would sound more natural to switch these two phrases.
However, it seems that responses are very rarely helpful. Instead, more often then not, they contain information on a different subject altogether.
I think this would flow better.
Stranger still
Off-tone.
activate itself expounding data from its reel.
Add comma after "itself".
itself shutting back down.
Make this "itself and shuts back down".
cover over the device with its carry case
This is a little too verbose.
once again
Not necessary.
feel uneasy, or fearful
No comma needed.
However reproductions of the sound have proven completely null to the effect.
I would delete "however".
