"Our brians (sic) are wired for quick recognition. For that we needed data reduction and trigger recognition. If we actually put the entire sound to long term memory the time it would take to process it because of the massive amount of data would be self defeating. We would lose the food and become the food while waiting to process and match the sounds."

Life of Brian?

Early man had to be able to precisely locate potential enemy, man or beast, and calculate its speed and direction. Even it's acceleration, the rate of velocity change. So early man had to have both hearing and vision skills, along with precision memory skills, including ability to integrate on the fly. A skill by the way the squirrel never acquired, the squirrel can't determine how fast a car is traveling or the direction it's going.

" As such our long term aural memories are reduced to a very very very small fraction of the original signal. Our brains fill in the rest of the missing data."

A person's ability to retain memories of sound are a combination of innate ability to remember and skill acquired by learning and practice. If you're unable to remember what you heard the day before how can audiophiles progress? You have to be able to determine whether the sound is better or worse or about the same. Whether it's a cable or preamp or tweak or during the night versus daytime, whatever.

You have to be trained to know what to listen for before you can put it all in memory. Otherwise there won't be much of anything in memory. It's like reading a book, some people have much greater reading comprehension than average so their memories will be more complete.
