The very first location cannot be missed as it is a part of the tutorial at the beginning of the game. The rest of the logs(besides #30) can all be found on Mombasa Streets Rally Point 4.

I will be posting what the actual device you interact with looks like and then a location on the map of where it is..

THEY CAN BE FOUND IN ANY ORDER YOU CHOOSE!





























For the FINAL audio log, you will need to go to mission Data Hive and start at Rally Point 2
Have the NMPD npc follow you until you get to a part with a lot of Brutes and get to this area:


If you've been following along with the audio logs story, the NMPD's dialogue will have a cool ending, but he'll lead you into the room with the final audio log.

Thanks to Viper123_SWE for this info:

Word of advice? The Superintendent AI will actively try to guide you towards audio logs by changing billboards, enabling crosswalks, sounding car alarms and phones as well as play recordings such as "Yellow means yield!" for example. Makes looking for logs much easier.
