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. Natalie Bright's audio logs are yellow and primarily located inside of optional dungeons.
I've arranged all the collectibles in 1 video showing their locations based on the area and accessibility.
