I also found the audio files very helpful for studying. I used to have to purchase them from commercial sources. Those sources are still available, but it's not something I can endorse since they're not official AF products.
The AF decided not to generate MP3s of the handbook due to the small numbers of 'hits' on those links (cost/user)...things always change though. The AF has 2 things in the works, a digital app for AFH 1 and/or MP3 files for the AFH 1 (not officially approved yet).
Here are 2 options that I've started looking into to try to help.
1) If you convert the study guide to word (right click, open with word, give it a few minutes to convert, save as a word doc), you can set up the document to have it 'read' to you. (Open word, you may have to click Enable Content on the yellow bar, select the blue File tab at the top, select options, select customize ribbon, select all commands, scroll all the way down the list to find Speak, now click on the New Tab button, double click on Speak or click add Speak, click OK, at the top of the screen you have a new tab with the Speak feature).
To have it read, highlight or select all text and click Speak. It will read all selected text.
It's a little robotic and slow, but it might help sometimes.
If you turn it up, it'll hold your attention while studying.
2) yakitome.com is a free software that converts text to speech. You can watch a demo of it on youtube to see if you like it.
I hope this helps a little bit. for everyone..
