There are a total of 40 Audio Logs available in ReCore. I would recommend going for these after finishing the game to some degree. All are available in free roam after completing the game. Thomas Adam's audio logs are blue and are primarily located in close proximity to areas related to the main story.
I've arranged all the collectibles in 1 video showing their locations based on the area and accessibility.
