What are the requirements to get these? I’ve completed both sp campaigns and what ifs yet still haven’t got them all? 
Audio logs
You also get audio logs when you lose a map. Play both campaigns again and now lose every map 
I really have no idea what the criteria is. I beat the campaign on hard, hit level 20, and still had some missing. I eventually got the rest of them while playing random maps since then.
I think the best idea is to just keep playing until you get the achievement instead of focusing on it.
That’s what I’m doing, playing through on hard with friends, some of which have all the audio logs. Only want two, would be nice to know which levels though.
As for losing every level, that won’t be hard. The bots on hard with 6 of us are tough to beat.
Ok then, I’ve now played levels multiple times, completed it on Hard (which is two full playthroughs) and still have one friggin audio log left. What gives lol.
It’s Captain Clinton 6th one down??
I dunno what requirements are supposed to be met to get these but I’ve just been receiving them non-stop.
Pretty interesting though.

That’s the one I am missing as well. I have won and lost on pretty much every map online and played though the single player campaign on both sides and it still won’t unlock.
You continue to unlock them as you continue to play. It’s not like “Container City, Security, Medium difficulty win—Mokoena 3rd down” You get them for winning. Do you ALWAYS get one? Probably not. But you get them for winning.
The problem is I have 2 level 20 characters and working on the third. Playing over 50 hours and I had the rest of the audio logs maybe at level 19 on my first character. This last one just refuses to unlock. There has to be something to it other then just winning or playing a match.
I think its randomn, i just keep getting one or two every match. Just don;t foxus on it and eventually it will pop up 
You get them playing missions (campaign or freeplay). You get 1 for each win playing solo, and 2 for each win playing online (co-op or versus). There are 32 mission specific audio logs (2 per mission), and 42 common ones. So, if you are playing offline, you will need to play each level twice (making sure to satisfy all of the primary objectives on one of them), and then replay any additional 42 missions (campaign or freeplay, even the same one over and over). You can cut those numbers in half by playing online.
You do not get audio logs for leveling or for completing the challenges.

I was missing one when I turned lvl20. I tried playing online and redo all the campains in solo. Still no final audio tape. I eventually had to start solo free play with 0 and 1 as setting to play by myself (no bots). When attacking, do all the objectives (switch to each character to see what is available prior to completing the main objcetives). When defending, go to the defend point and wait it out. I took several maps for me to finally get the audio log. I think it I got the audio log for defending at the first defend point.
I got the last one in a random online game, went out of my to do the secondary objective. No idea if that was why it popped up?
Yep. The most commonly missed are the objective based ‘defense’ audio logs, since it requires that you shut-out the opponents on their very first objective. If you can’t defend the first objective, you don’t satisfy the requirements for the objective based audio log for that level.
Nope. Secondary objectives do not affect the audio logs. Tested it myself with a virgin account getting the achievement doing only custom “1 vs 0” freeplay missions. No AI to mess things up. No campaign missions. No challenges. No secondary objectives. Just 74 “primary objective only” missions (2 on each level, and the other 42 on the same one).
