"Human Action" on audio?
Don't listen to this while driving!
Oddly, I'm listening to Human Action while going around town on my bike. Maybe I'm just a weirdo, but I find deep reads great for focusing. Especially the sections where he lays out Ricardo's coordination theorems.
I like to "save up" the Human Action chapters until there's like 4 hours' worth of them and then listen to them at work around the time that it starts getting really dull. Great for engaging the mind while doing drudge work.
I also listened to The Ethics of Liberty, For a New Liberty, and Conceived in Liberty at work. Without which experience I might still be struggling to finally reject the state.
Also, Garet Garrett's book The Driver was just read by Riggenbach and released as Mises audio. It's sort of a proto-Atlas Shrugged, and I frankly enjoyed it more.
