Further research yielded something of note so I thought I'd share for any interested parties.
While searching the nearly 79,000 field recordings in the audio category on The Internet Archive, I found that most of the results were tagged as "radioaporee." Googling that expression led me to this -
radio aporee ::: global soundmap project
https://aporee.org/maps/
And Wikipedia's page for "sound map" cites the same URL under "External Links."
The site offers an interactive map of the world with field recordings sourced from each location, playable directly in a mobile or desktop browser.
And another similar site is:
